5.0 out of 5 starsGreat headphones, iffy connectivity
Reviewed in the United States on March 16, 2024
These headphones are among the best I've ever heard; their sound quality is unmatched in the area. Sennheiser is well known for this, and definitely live up to expectations here. You can tune them to your liking with an optional bass boost toggle in the app that makes music very punchy, which in my opinion adds a lot to these headphones.

While the experience on mobile has been seamless with no issues, the same cannot be said for desktop. Periodically on desktop there is connection dropout with bursts of static upon reconnection.

Notwithstanding the connection, this pair of headphones are my first with ANC. I think it works well enough, although from what I've seen it's hardly comparable to Sony's XM5s.

The touch controls are sensitive, as many others have said. However, I don't find it to be much of an issue on a day-to-day basis. While having buttons would be nice, I find the touch controls to be rather intuitive and have come to like them.

Overall, with the great sound and controls, I can easily say it's worth the price and more than makes up for the slight issues that you may come across when using them. I am more leaning towards 4 stars for this review, but in my personal opinion it gets a 5.

1.0 out of 5 starsThe audio quality is superb, but completely ruined by the software
Reviewed in the United States on May 15, 2023
(This is copy-pasted from my Trustpilot review:

I don't understand how on Earth a headset can have such good build quality and amazing audio quality, but the software can be so bad it's laughable. I will be returning my headset (Momentum 4 wireless).

To start out, the audio quality is AMAZING. I'm coming from the sony WH1000-XM4s. It's the best I've ever head. I can differentiate between 16 bit and 24 bit very reliably. Lossy audio over Bluetooth is very noticeable now. No complaints there.

The build quality is also really nice. I love the materials used, the weight, and how the headband extends. All around really nice feel.

The software that the headset has, on the other had, completely ruins all of that. Here's a list of every problem I've noticed in the two days I've had my hands on it:

- There is no ability to turn ANC or transparency off. You must choose one at all times.

- Transparency mode makes things twice as loud for some reason. I literally don't know where to start with this

- There's no palm detection for the touch gestures to quickly enable transparency mode. Does the headset not have multitouch hardware? If so, why?

- There's no way to customize the touch gestures. It even says this in the app. That's rediculous.

- If you have the automatic play-pause feature turned on, which pauses the music when you take the headset off, and plays it when you put it back on, the tones even if you're using the headphone cable. I haven't tested with a four pole cable, but the included one is three poles so I'm going to deduct that the headset doesn't have the ability to play/pause when using the headphone cable.
-Firmware update takes half an hour??? Why?

- The app really, really buggy slow, and generally difficult to use.

- When using USB connection, if you activate the microphone it goes to some really low quality mono audio mode for no apparent reason. Is this something the headset does where it thinks it's in a phone call when the microphone is on, so it just does this with no second thought?

- ANC is really bad. It is laughably bad. In adaptive mode, any sudden or sharp noise, no matter how small reduces the ANC effect. It's really noticable and distracting, especially when typing. In non-adaptive mode, the ANC does essentially nothing.

- I have voice prompts turned off but it still talks to me when I connect to bluetooth. It also says how much battery I have when I touch the power button, even though there's LEDs on the bottom which show battery charge. I have it turned off, I expect it off.

- You can adjust the volume when using the headphone jack. This is really confusing.

- This isn't a software issue, but why does it use a 2.5mm headphone jack? There seems to be no reason to do this since the cups are plenty large enough to support an extra mm. The included cable also doesn't have any clear markings on which end is the 2.5mm one.

- The touch gestures are really stupid. A single tap to do anything is a really bad decision, since it's very easy to accidentally touch the touch-sensitive area when adjusting the earphone. And again, they can't be customized. Like what? Why? That should take a software engineer like a day to implement, at worst.

I don't get it. Is this intentional? There's no way Senheizer is ignorant to these problems. Do they not test stuff at all? This is really bad. There's gotta be some really abhorrent management problems over at Sennheizer for it to be this bad. These headphones have been out for a year (released August 9th, 2022) and every issue in my list should have never been present at any point during release. This is really, really bad. I'll be staying away from Sennheizer for a very long time, and you should to. I expect way more from flagship headphones.

5.0 out of 5 stars Great buy-- app is good and very comfortable fit
Reviewed in the United States on February 25, 2024
Color: Black/CopperStyle: Special EditionPattern: HeadphonesVerified Purchase
I got my pair in from Amazon today. First impressions are great. When I pulled them out of the box, there was around a 50 percent charge, so I was able to try them out immediately. I have an iPhone with the latest iOS, so pairing was very easy. Immediately when I paired them, there was a firmware update which took around 5 minutes to download and install over bluetooth. The app is good and works well. You can create soundstages by location and control noise cancellation via a slider. There is a simple EQ as well.

I am coming from an older pair of B&O H95's and Bose quiet comforts Q45. While the Bose were very comfortable and the noise cancellation was awesome-- I did not realize how bad they sounded until I got my older paid of H95's. This pair of Sennheisers sounds so much better than the quiet comforts. There is really no competition there. They don't sound quite as good as the H95's but the H95's give me a headache as far as the clamping on the sides of the head. Please note for those of you who wear glasses-- these Sennheisers are the best headphones for people who wear glasses-- much better than the Bose.

So for comparisons, I would give the H95's a 9 on sound quality, a 5 on battery life, a 2 on comfort and a 5 on noise cancellation (out of a scale of 10). B & O app on iOS-- 7. Build quality for the H95 would be a 8.5
Bose Quiet Comforts Q45 a 4 on sound quality, a 7 on battery life, a 8.5 on comfort and a 10 on noise cancellation. The Bose app is not good at all. I could never get it paired correctly except through the Bluetooth iOS control panel. This is on multiple devices. The app for me gets a 0. Build quality is a 7-- all plastic.
For the Sennheisers-- a 8 on sound quality, a 10 on battery life, a 10 on comfort and a 7 on noise cancellation. I had zero issues with the app and there are so many options for personalization-- that gets a 10 on iOS. Build quality-- gets a 9.5

Now-- a question I had are these worth the price-- absolutely. I was wondering that myself. I really think they are worth it. It is easy to future proof these with the firmware updates that are easy to install.
Bass quality-- gets a 4 out of 5 stars as the Bass is a little weak (even with Bass boost) compared to the H95's. Noise cancellation is good but not quite as good as the Bose. But a tradeoff I am willing to make is the sound quality is soo much better with the Sennheisers compared to the Bose.

The best part is-- these do not give me a headache (been wearing them all day) and no clamping on the sides of my head.

5.0 out of 5 stars What you need to know...
Reviewed in the United States on December 21, 2023
Color: BlackStyle: OriginalPattern: HeadphonesVerified Purchase
Before buying these, you gotta know some things. First, if you listen to earbuds a lot, over-ear headphones sound different. The sound is less directly in your ear, and more around you. As such, there is less impact. That doesn't mean these aren't good, they're just not shoved into your ear.

Second, the source makes or breaks these. A crappy source will sound crappy on these and you'll end up blaming the headphones. It's actually a feature of the headphones though. They reproduce what you put into them very well. Go into Spotify and mess with the EQ there if you feel the need. I like sharp treble and got it that way. Change the stream setting to highest quality. Plug them into a good digital to analog converter (DAC). Try different sources and you'll see whatever you may not be liking is not the headphones. As an acoustic guitarist, I was hoping for the same sound I get with my Martin on my lap. I'd love to have headphones that sound like Tony Rice and Dave Grisman are standing on either side of me, but that's not gonna happen. Again, the source matters. These headphones are not a hand-built American acoustic guitar played by a master standing next to you, but they'll sound more like it than the majority of headphones.

Third, we've become programmed to in-your-face sound. These Momentum 4 are very much "grown-up" headphones. They articulate. They detail. The present. But they don't floor you with over-the-top sound all through the range. There are plenty of good, inexpensive headphones and earbuds that will pop your eardrums. I personally recommend Anker for that. My Space A40 earbuds are awesome, but when I A/B tested the A40 and these Momentum 4, I realized there were instruments I didn't even realize were there when listening with the A40 earbuds.

Fourth, the bluetooth is dumb at first. From what I can tell, they won't work like you'd expect until you launch the app as part of the connection process. It's fine though. Just don't give up on them right off the bat because of that.

Other random thoughts - they're super UNcomfortable right away, become very comfortable rather quickly - like within minutes. Also, good headphones do have a break-in period, and these are no exception. Be sure to try the wired connection on some different sources as well. MacBooks have good DACs in them. Anker makes a good USB-C to aux adapter with a DAC in it. The bluetooth connection can sound pretty dang good though. And the microphones in this headset are almost creepy-good. Also, bluetooth range is perfectly fine. I went three rooms away in my house with no issues at all.

Summary - I was thinking of returning these, but I know Sennheiser so I messed with settings and connections and I'm glad I did. They're great headphones, but the key is to remember - if your source is crap, they will faithfully reproduce that crap.

4.0 out of 5 stars Exceptional sound quality, great battery life. Noise cancellation is OK. Updates could make it 5/5.
Reviewed in the United States on September 29, 2022
Color: BlackStyle: OriginalPattern: HeadphonesVerified Purchase
Sound quality on these is GREAT - No complaints whatsoever. Music sounds good, TV dialogue is easily understandable, full range of sound is audible. Mic quality is good, but not as top of the line as the sound.

Battery life is pretty in line with what's advertised. Expect to charge at least twice weekly if you use your headphones heavily.

I'm not crazy about the touch controls. They seem finicky to me, and don't give you good feedback. Instead of being able to adjust transparency on a percentage scale, I'd much rather have a quick switch for going between fully transparent and fully noise cancelling.

I had some problems initially with pairing and set up. When connected to my Windows 10 PC, they appear as two different sound devices - Headphones & headset. Quality when connected as a headset is terrible, so make sure it's connected as headphones. Headset connection can be disabled in output devices if it's connecting the wrong one as default, but make sure it's left enabled in the input devices list or you won't be able to use the microphone.

The app is...Not great. No desktop version as far as I can tell, so you have to control it from a phone or emulator. I ended up turning off almost all of the app features. Auto adjusting noise cancellation didn't seem to work properly, and I have no idea what "Comfort calling" is because most of the app features don't have descriptions (This one isn't listed in the manual either). On head detection has annoyed me with every device I've ever had it on, but I'll concede that before I turned it off this was the least terrible implementation that I've experienced.

Initial pairing experience was troublesome, but now that all my devices (Desktop, laptop, phone) are paired I'm able to transition between them all pretty smoothly. Occasionally I'll have to turn bluetooth off on one device or another because I'll get continuous "Connected/Disconnected" messages while listening on a different device.

Bottom line, if audio quality is your most important factor in looking for headphones, you'll probably be happy with these - I definitely am. That being said, they aren't the most user friendly headphones currently. I'm hoping that software/firmware updates might improve the experience, and I'll update this review if that happens.

5.0 out of 5 stars Smaller cups than other Sennheiser - amazing anyway, read full review
Reviewed in the United States on May 2, 2023
Color: BlackStyle: OriginalPattern: HeadphonesVerified Purchase
You're a smart person, you can find the frequency response curves, ANC curves, etc. online. This review is about the overall experience. Note: I happen to LOVE the way these look, simple, plain, understated... smaller target for theft, too.

I have the Sennheiser HD 515, HD 598, and HD 598 Cs, and the Sennheiser GAME ONE headset. Those (and most other from the brand) have large, extremely comfortable ear cups. I know that, and need that, because I used to play World of Warcraft for about 50 hours a week, with headphones all the time.

First impression—the cups are smaller. It just so happens that I have normal ears, and the other Sennheisers I have are too big for me, with a good margin to adjust them when the skin gets tired around my earlobes. The MOMENTUM 4 surprised me by being smaller, but—they have a really good design and are concave, with more space inside the cup than it seems, especially in the back. I am able to find a few different positions where my earlobes are not pressed (or even touched) at all, but how they fit you will depend on your ears, which is something important to consider.

The review at SoundGuys is on point. The M4 do have a bit more low end than my other sets, and I like that; it's easier to EQ your way down than up. Overall very happy with the sound, I don't think you'd be disappointed. As the SG review says, the ANC is a little weak sometimes; I don't care, to me that's secondary.

Battery life is amazing, the 60hrs claim seems accurate. Build quality is plasticky and okay, I would baby them a bit. Touch controls are precise and responsive for me, even with the guide stickers still on the outside (which I've removed after my wife made fun of me for it). The app seems to work all right, I think it's better to set your preferences and then not use it anymore, as sometimes the settings get changed around a bit for no reason. (KEEP UP WITH FIRMWARE UPDATES, though.)

Connectivity—outstanding. Bluetooth (multipoint x2), passive mode, and USB mode. Quickly:

* Bluetooth: works fine. Good range, it seems. I don't care for or like the multipoint, and I think it's irrelevant.
* USB mode: use USB-A to USB Type C cable (included). Headphone presents as a regular USB headset to the computer. Works great and charges at the same time.
* Passive mode: Uses a 3.5mm to 2.5mm cable (included) to use as a plain Jane wired headset. You CAN power on the M4 in this mode and benefit from better sound, or leave them off (on purpose, or if the battery is dead). I DISAGREE THAT THE SOUND IS BAD IN PURE PASSIVE MODE, WITH POWER OFF. It's slightly subpar compared to BT/USB/powered passive, but it's JUST FINE, and pretty good to boot.

The SG review docks the M4 on mic quality, but in my tests people's feedback was that the calls were clear and noise-free, even when I was doing yard work on a very windy day. Still, YMMV.

Case—it's a carrying case. It's... functional, plain, the way I like my coffee.

My only complaint, if this tells you anything—the charge port and 2.5mm port are on the RIGHT cup, whereas all other sets I've ever had or seen have the cable going to the LEFT one. The power button and touch controls are also on the RIGHT, so maybe that's why, but on the (infrequent) occasions when you may have a cable attached, it's not where you'd be used to finding it.

3.0 out of 5 stars Good on paper, bad on my head
Reviewed in the United States on February 3, 2023
Color: BlackStyle: OriginalPattern: HeadphonesVerified Purchase
I was going back and forth between Sony WH-1000XM5 (XM5) and these headphones (SM4), and I decided to give these a shot since at the time of this purchase, I was able to get these for $279.83 before taxes while the XM5 are listed at ~$400 before taxes.
On paper, the SM4 sounded great, double the battery life, supposedly better sound quality, and a not-so-shabby noise cancelling.
However, after trying them for a week, I decided to return them. I will list the pros and cons below.

PROS
1. Long battery life – I only charged it once during the whole week and it was still going strong.
2. Very solid construction – premium materials that feel good to the touch.
3. Pretty nice carrying case – feels solid and durable, and you don't need to fold the headphones when you put it in so it's simpler to stow in case. BUT I have to reset the positions of the earcups to fit into case, which means I have to always re-adjust to my head size before putting it on.
4. Great sound – I'm not an audiophile, but it sounded good. A friend said he picked up on more chords behind a Taylor Swift song that he hasn't heard before (he listens to Taylor Swift 24/7).
5. Sleek design – unlike the SM3, the SM4 has design that I like: minimalistic and modern.

CONS
1. Subpar app-headphone interface – the app is glitchy, and I find myself wait around 10 seconds for the app to say "connected" to the headphones (even though the headphones are connected to my iPhone via Bluetooth); after which point, I can go in and change some settings. Also, I did have some stutters in the app that gave me an overall feel of unpolished.
2. Too heavy and too much clamping force – on paper, the weight and clamping force differs by 0.1-ish, but from trying out my friends' XM5s and my SM4, I feel a pretty noticeable difference in how hefty the headphones feel on my head. Simply put, SM4 feels tight on my head and XM5 feels like I can forget that I’m wearing them after a while—this is personal preference, but personally, SM4 felt less comfortable and a tad too heavy for long study sessions.
3. Headache-inducing noise cancelling – the noise cancel isn't as good as the XM5 indeed, but I think there is a bigger problem: the noise cancelling feels peculiarly headache-y. I have airpod pros, plus I have tried the XM5s, and I have to say, the SM4's noise cancelling is by far my least favorite. If I were to describe it, I would say it feels like the feeling I get from being on an airplane for 5+ hours with headphones on. All in all, I opted to have no noise cancelling on due to this uncomfortable feeling it gives me.
4. Touch control – the touch control is pretty responsive, but even if I touch the very edge of the earcups, it registers as a gesture, which gets annoying when I'm trying to adjust my headphones or taking them off for a second. After a few days, I almost wanted to turn them off. ALSO, XM5's cupping gesture to activate transparency mode is extremely desirable, especially since I'm a college student who finds myself studying with my friends a lot. AND the SM4 does not have a gesture to turn off noise cancelling; I have to either pinch in/out multiple times or go into the app and adjust the slider, and it gets very annoying quick.

If you have read this far, I applaud your diligence to find the best headphones for you. Personally, I have ordered the XM5 and I will try it on and probably keep it. BUT, an advise for you if you are like me. I dug through the internet and have looked at countless written, video, and professional reviews of so many headphones, but I have to say, it all comes down to personal preference. You MUST go to a Best Buy, where they have headphones on racks that you can try on for yourself. Also, don’t be afraid to order them on amazon and try it out for a week and return them and move onto the next one. Amazon’s return policy is pretty good and if you use the headphones with care and keep the packaging that the headphones came in, you can most likely return them for free. I hope you find the right pair of headphones for yourself, reader.

2.0 out of 5 stars Great sound, bad UX Design.
Reviewed in the United States on March 8, 2024

The PXC-550 headphones were my go-to for the past three years, striking the perfect balance between quality sound and comfort, with just a couple of drawbacks: a lack of USB-C support and less-than-ideal battery life. Eager for an upgrade, I transitioned to their successor MOMENTUM, hoping for improvements. On paper, the new model seemed to promise just that—a better, more refined listening experience. However, while the upgrade delivered in some areas, it faltered in others, revealing design flaws that the PXC-550 had already mastered.

On the plus side, the sound quality is exceptional, with noise cancellation that effectively silences the outside world, and a battery life that feels almost endless. These improvements alone make the headphones a significant leap forward.

But not all changes are for the better. The new design is bulkier. More frustratingly, the intuitive fold-to-turn-off (and on) feature of the PXC-550 has been omitted. The satisfying click of the folding switch, which once brought a sudden moment of reassurance—a Deus ex Machina moment between you and this piece of machinery—is gone. Now, turning off the headphones requires holding down a button for an awkwardly long pause, a process that can accidentally trigger pairing mode instead of powering down. This seemingly small change significantly impacts the user experience, transforming seamless transitions into moments of annoyance.

Imagine this: You're about to start your car journey, only to discover your headphones have remained on, constantly attempting to connect to your phone, disrupting the peace of your drive. Or picture yourself at your desk, a sudden visitor arrives, and you're caught in an awkward dance of trying to turn off your headphones, a delay that interrupts the flow of life.

This shift from the elegantly simple act of folding your headphones to turn them off and on to a cumbersome, button-dependent process adds up, not just in seconds wasted but in the sheer inconvenience it represents, especially when you know how effortless it once was. The PXC-550 made life smoother, akin to having a trusted steed by your side in the relentless battle of daily existence—a companion so reliable, its absence is profoundly felt.

In light of these experiences, one can't help but yearn for a simple solution: a PXC-550 reimagined with USB-C. Such a proposition seems a minor ask for the return of what was lost—the instant gratification and reassurance of effortlessly powering down by folding, a feature that made the PXC-550 an indispensable part of life's arsenal.

One could say that the new headphones, while technologically superior, miss the mark on understanding the rhythm of life. The joy of technology is not just in its capability but in its ability to blend seamlessly into our lives, enhancing without complicating. The previous model understood this, becoming more than just a tool for listening—it was a companion in the epic battle of everyday life.

As it stands, despite its technological strides, the newer model leaves something to be desired for those of us who cherish both the journey and the simplicity of interaction with our gadgets. In essence, the quest for improvement should not forsake the intuitive pleasures of the past.

Btw 80 seconds a day with this button nonsense, equals to 8 hours a years of frustration.

3.0 out of 5 stars I wanted to love these...
Reviewed in the United States on December 4, 2023
Color: Black/CopperStyle: Special EditionPattern: HeadphonesVerified Purchase
I own another pair of Sennheiser headphones, the 598SE's, and they're spectacular. They're spacious, clear, wonderful sound stage, light, and powerful.
After trying a few other brands of ANC headphones, I learned about the Momentum 4's and immediately thought: OK, Sennheiser is gonna knock it out of the park.
Unfortunately, they only got to first base.

First, the good:
I love how these look, especially the copper accented special edition's that I got. The fabric on the top of the headband makes it look classy.
The sound is wonderful. Absolutely the best thing about this product. The sound stage compared to the other major competitors is still a step above.
The carrying case is nice, roughly the same size as their competitors. I did wish it could have been a bit smaller (this goes for the competitors too).
The swipe controls are the same as a major competitor, which you can also lock. I really like the swipe controls, though having physical buttons would be nice too, especially if you lock the swipe controls.
The battery life is beyond spectacular. It destroys their competition and you could probably wear these for several days without needing a charge.

Now, the bad:
They're quite heavy. The weight on paper seems like they'd be fine, but while wearing them I quickly got fatigued and felt frustrated wearing them (while their competitors, it took much longer to get to that point).
They get hot. Not the headset itself, but they form a seal on your head and you'll feel your ears cooking after a short while in a comfortable temperature room. This was another reason I frequently took them off.
The earcups are small. They seem EVER SO SLIGHTLY larger than their competitors but... not enough. The 598SE's have big beautiful spacious earcups but these (and their competitors) are very cramped.
The ANC is notably weaker in a perfect environment without noise playing than others. With others, I could barely make out any words while playing a song or video rather loud as a test. With the Sennheisers I could make out quite a bit of words and sound. The Momentum 4's have fewer ANC microphones than the competitors.
The ANC also almost drops out completely if you have "windy environment mode" turned on, for some reason. (Note: I did not test them in a windy environment) If the ANC is important, make sure you have this setting *TURNED OFF* in the app.
The app is ok, but what you can "control" seems finicky and sometimes its as if changing settings did nothing.
The call volume is like 5 generations ago hands-free headset. Very poor quality. The person I tested them with said it sounded like I was outdoors or in a noisy environment when I was in a quiet room.
The clamping is quite tight and becomes painful very quickly. It puts a lot of pressure around your ear which can become very uncomfortable. A friend said they loosen up after a couple days but mine stayed far too tight. It felt like a vice. [If it doesnt bother you, this could be a plus, as they seem like they will hold their shape and tightness for a long time]
Even lacking almost any physical buttons, they basically threaten you to not get these wet. There is no waterproofing on these. Handle with care.

The rest:
These are by no means a "bad" set of wireless ANC cans, and the price is good, especially if you can get them on sale. If you're just going to be using them in the office or on a commute, they'll probably be fine, especially if you dont want to dole out extra cash for a minor upgrade in ANC. The middling ANC was quite disappointing, but if you have some sounds playing while its on, it works together to make most noises disappear. Unfortunately, sometimes I want to be able to just block out the world, and the Momentum 4's were just not up to the task compared to others.
I was really hoping the earcups would be larger and more similar to other Sennheiser headsets I've tried/owned, but they seemed to want to copy the competition, which is a shame. If the cups were larger and the clamping a bit less harsh, I would have accepted their flaws and gone with these. With the laundry list of negatives, you can probably tell why I didnt.
Also please note: I am a big guy, and I probably have a larger than average head. This could be contributing to the clamping pressure.
Listening to anything on these was a treat. Everything sounded beautiful. Other brands should take a few notes on Sennheisers drivers.
I had two main requirements: comfortable ear cups (failed) and long battery life for an upcoming flight (wow did these pass with not flying colors but to outerspace and back colors!). Unfortunately, as they were just not at all comfortable (I could wear my 598SE's for days and not even realize they're there). Their long battery life did not offset the negatives.

This may all not be true for you. They definitely stand out and are far more attractive than the competition (at least, the special edition versions are). I am definitely biased towards Sennheiser as I have loved so many of their headsets, but found these disappointing in far too many areas. A few design tweaks could have made these one of the best over the ear cans on the market. As is, they're probably ranked 4th imho.

4.0 out of 5 stars Sennheiser Sound is top notch
Reviewed in the United States on February 26, 2024
Color: Black/CopperStyle: Special EditionPattern: HeadphonesVerified Purchase
TLDR; great sound with pretty good ANC.

First, I'm not an audiophile. I appreciate music and sound more than just "MOAR BASS" but as to warmth, tonality, and terms like that, I'm lost. I do know having worn open back headphones those have a great sound space compared to closed back, but my wife can't stand hearing my music so it's closed back headphones for me.

Positive:
1. Great sound. Between these, some Senns 598s, true momentum earbuds, I've never not liked the sound Sennheiser produces. Earbuds were the weakest, but those were Momentum 2s and didn't last long when my dogs chewed on them (I understand Sennheiser has improved as well).
1A. I cannot understate how good these sound - I literally can hear Chester Bennington pushing his breath out on "Lost", and instruments I've never picked up before. I can't recall other headsets doing that for me.

2. Comfortable - immediately comfortable out of the box. Maybe warms up my ears a bit much, but the benefit is a solidly closed "box" for my ears to listen without distraction.

3. Battery life appears to be as epic as they say it is. I haven't rocked it solid for 50+ hours to find out but I've charged it like once, when I first got it a few weeks ago (not constantly listening)

Unknowns: need to test the ANC on an airplane/airport setting, which is my biggest pet peeve for noise environments. Will try to update (if I remember) once I do.

Negatives:

1. Touch controls in general. It's not just Sennheiser, but Sony and others im sure. I just don't really want to take the time to remember if it's a swipe, pinch, double-triple-quad tap to do something. KISS should be the rule of thumb. I can stumble through by tapping/swiping either side and eventually find something close to what I want, but I usually end up in the Sennheiser Smart Control App to make sure the ANC is what I want.

Comparison:

I also got a Sony WH-1000XM5 recently. Also a very good headphone, but the sound is absolutely not as good as Sennheiser. ANC is top of class though (although I also have t tried it in an airport/airplane, just in my commutes), and is better than Sennheiser, it's not as huge a gap as it used to be. We're comparing a Porsche and a BMW; should anyone turn either of them down? No.

It comes down to your personal needs: lots of travel(air, train, whatever) in noisy environments? Maybe go with Sony, but I'd try the Sennheiser Momentum 4s first to see if their ANC works for you. IMO, the Sennheiser sound quality is much better than Sony's sound more than Sony's ANC is better than Sennheiser's.
