I am using my review as a way to communicate a confusing problem that I was able to figure out on my own.
As for my review:
- Sounds amazing
- a bit tight (I have a medium/smaller sized head), will have to break them in more before extended periods of use.
- The ANC is just as I expected and the fact they work as a headset is great too!
- The mic quality is not ideal and terrible in the wind. It's nice to have in a pinch so you don't have to raise your phone to your mouth, but I wouldn't recommend trying to do any business that needs high-quality audio).
- Battery life is solid and the USB-C is so convenient! Plus a clear voice that lets you know if they are powering on or off.
- Easy to connect, a bit confusing to master (hence the second part of this review)
Great Value Headphones, Meh as a Headset.
---------- How to toggle "Transparency/pass-through Mode" & "ANC Mode"? ------------
I found a few comments mentioning that you are unable to turn it off the "Transparency Mode" or the pass-through sounds that are made ambiently around you, like voices, crinkling paper, and typing. This is not the same as ANC(Active Noice Cancellation) which removes only the ambient hum of the room like a fan, refrigerator, or airplane.
This particular headset actually has two BlueTooth Connections or "drivers" on windows and mac.
"Headphones (LE-HD 450BT Stereo)" & "Headset (HD 450BT Hands-Free AG Audio)"
Mobile devices seem to auto-switch between these depending on if they are utilizing the mic in the Headset or not.
Headphones (LE-HD 450BT Stereo): Does not utilize Transparency Mode, however ANC can be toggled. (Set this as "Default" if you do not want to here the Transparency mode)
Headset (HD 450BT Hands-Free AG Audio): Seems to default Transparency Mode ON, and ANC can also be toggled when this is active as well. (If you make a lot of calls and utilize the mic setting this to "Default" may be more useful) If you use the Assistant button, this will automatically switch to this driver, but will revert if you have the headphones selected as "Default".
**Extra Notes**
If you have a 5.0 BlueTooth (internal or as an adapter) for your computer both of these are able to connect and you can toggle between these in your sound settings. Most modern mobile devices as of July 2016+ have this installed but you may use the AIDA64 app on the Google Play store to see if it's in your device.
Apple Users: iPhone 8, iPhone 8 Plus, iPhone X, HomePod, and the 2018 MacBook Pro with Touch Bar all (and newer devices) utilize the 5.0 or newer BlueTooth.
I do not know what happens if you have an older version of BlueTooth, however, I speculate that switching between the two drivers may be clunky, and slower than it already is. However they will still connect, you may just run into issues connecting other devices simultaneously like a mouse and keyboard.
The S 450BT WILL usually prioritize headphone mode, however, I hope this helps if you were confused.
If you use the Headphone Jack it will put the headphones in Flight Mode and deactivate all BlueTooth Connections.

Bland Design | Flat Sound | Mediocre ANC
I am a fan of Sennheiser and have used its products in the past. But this pair of active noise-canceling headphones is a true letdown! Pros 👍👍👍 - Build: Solid with no creaks or gaps.- Compact: They fold down and pack small.- Comfortable to wear with room for adjustment.- Versatile: they can be used wired & wireless.- Battery Life: up to 30 hours with USB-C fast charging.- It comes with a carry case.- 2-year warranty is commendable.Cons 👎👎👎 - Controls: A bunch of buttons crammed together with no rhyme or reason, no labeling, and no easy way to navigate by touch! 😑- Voice Prompts: It tells you everything, except for the one thing you need the most—it won’t tell when ANC is on or off! It’s infuriating! 😤- Active Noise Canceling (ANC): It makes a difference, but it’s negligible at best!- Audio Tuning: Everything sounds flat and lifeless, with volume bouncing up and down inexplicably! 😳- No Proximity Sensor so they don’t pause when take them off which is real nuisance 😑- SE stands for Special Edition, but I can’t figure out what's so special about them. Seriously, what is it?🤔- The Price You Pay: At $200 MSRP, this set is a hard sell! On sale for $80, it’s still a pass for me! Pay a few bucks more and get a Sony WH-CH720N, or if you’re on a really tight budget, get Anker’s Soundcore Q20 for $40–$60.My Verdict 🧐 I am not here to bash Sennheiser or throw shade at its good name, but I cannot in good conscience recommend this product, especially if you’re planning on using it while traveling. Skip this or suffer buyer’s remorse! You may think I’ve come down hard on Sennheiser in this review, and maybe I did, but those headphones are the worst I’ve ever come across, except for only the Koss KPH7, but those were $20 and made no claims to greatness!I hope my review will help you make a more informed buying decision 👍😊✌️
