5.0 out of 5 starsAfter 20 years of using Bose (and 2 Bose headsets at home), moved to Sony 1000XM3
Reviewed in the United States on February 2, 2020
I had Bose headsets for travel for over 20 years. I had Bose QC-1, QC-2; I still have QC-20 wired earbuds and aviation headset A20. Recently, I had a challenge of finding headset which not only works to cancel noise in an airplane, but which also works better than earplugs at home, especially to reduce noise of piano played in a different room. I compared Sony 1000XM3 with Bose QC35 and 700 at a store, bought two pairs of Sony, and compared them with Bose QC-20 and A20. On top of that, I did tons of research.
To begin with, Bose used to be "the king of noise cancellation" for many years. This reign is coming to an end: the competition is fierce. In pro aviation world, Lightspeed created a strong competition to Bose, while in the consumer world, Sony came up with a product widely superior in noise cancellation. Bose tried to answer Sony with Bose 700, but it is still inferior in noise cancellation and usability and features of the phone app.
According to independent testing data available on the internet, Sony's noise cancellation is up to 6 dB better than Bose. If you are not familiar with dB scale, it is a log scale, and 6 dB is a little more than a factor of 2. Noise cancellation efficiency is frequency dependent, so it is hard to compare apples to apples. Power spectrum across all frequency gives an about 2 dB advantage to Sony (29 dB compared to 27 dB of Bose 700), in low frequency range Sony beats Bose with a high margin (about 6 dB), in high frequency range Bose appears to be better. Yet, when you put Sony on your head, followed by Bose, and switch back and forth, Sony is impressively better. Like, way better. Tons better. So much better that you sometimes wonder if Bose is turned on at all.
Comparing Sony XM3 with Bose QC20, Sony is better in all respects other than small size and weight of QC20. Noise cancellation is better, and sound quality is better. Comparison with aviation headset A20 shows that A20 is slightly superior in terms of noise cancellation (and, surprisingly, even in sound quality), probably due to a passive noise cancellation component - but A20 is a $1100 headset with a massive wire and console, and connectors are not compatible with consumer electronics. You would never consider it unless you fly an airplane as a pilot. High frequency hissing, which existed up to QC15 and still present in A20 (introduced in 2015) is almost gone in both newer Bose and in Sony. Difference in noise cancellation quality between Bose A20 and Sony XM3 is worth maybe $50, but not $800. I think we are talking about several dB, nothing major.
Sound quality is subjective. Neither Sony nor Bose 700 are audiophile grade. One cannot tell the difference while playing music via Bluetooth from a phone, but plug them with a cable into a headphone amplifier and play 24/96 music, compare with Hi-Fi headphones (I have good old Sennheiser HD-620 which used to be in the top 10 best some 20 years ago; not anymore, but they are still great sounding high end headphones) - and you can tell immediately that these are not Hi-Fi headphones. Not even close. With a good sound source, they sound dull and sound stage is not there. But they sound well enough for daily use, for playing music from the phone, certainly better than most earbuds. Sony sounds a little better than Bose 700 to my taste, but it is close, very close, there are small difference in color of the sound which are very subjective. I rated the sound five stars because this is not a Hi-Fi headset, it is a noise cancelling headset, and the price is determined primarily by its noise cancellation abilities. As long as you can listen to music and enjoy it, as long as it does not sound like cheap earbuds, it is OK. For really high quality of sound without noise cancellation, there are much better options in the same price range.
App is not required with Sony and Bose (despite misleading information on the web, either headset can be used without the app), but Sony app is much better. It does not require registration and has many more features, including adjustment of noise cancellation to ambient pressure.
Sony, to my surprise, works very well for phone calls in the office environment. There were many reports that Bose was vastly superior, perhaps this is the case when one needs aggressive noise cancellation, like on the street among cars and people. Or maybe Sony made updates to firmware which fixed the issues which they had. When answering calls at home, the sound quality on the other end of the line is excellent. People cannot tell I am wearing a headset.
Comfort is purely subjective and depends on one's head size and shape. I have a big head, so most headphones exert some pressure. Sony is no exception, but I am fine with that. I must say, the most comfortable headset for my head is Bose QC 35 II, followed by Sony XM3 and followed by Bose 700. Bose 700 feels a tad cooler on the ears. A20 creates too much pressure on my ears.
For travel (e.g., vacation) QC20 is hard to beat, due to their very small size. They are inferior to XM3 or latest Bose, but do their job well enough. For use at home or in the office, bluetooth headsets with better noise cancellation and better sound and with the ability to make calls are the way to go.
Finally, cancellation of piano sounds. My wife teaches piano full time from home. Sound is a problem in our home. When I am in the same room as our grand piano, I can hear it loud and clear, although much less loud than without the headset. However, when I go to my office and close the door (which is a glass door which only partially blocks the sounds), I can barely hear it and can focus on whatever I am doing without distraction from the sounds. I tried QC20 for this purpose, and they were not quite up to the task. I got the 33 NRR rated 3M earplugs, and they also were not perfect either. I can tell that Sony XM3 works better. I would not use XM3 to work with power tools, though. They are too expensive and possibly too fragile for a workshop, and the benefit is not large enough to warrant the difference in price.
Build quality of Sony seems to be better than Bose (and less expensive, too). The headset is made in Malaysia. Bose, I must say, can make great quality headsets (A20, with 5 years warranty, is an evidence to that), but consumer grade headsets always had an almost marginal quality. Bose, by the way, does not repair them once they are out of warranty. They make you buy new ones with a discount. Two of my old Bose headphones broke and I had to replace them because repair option was not offered, and lifetime of synthetic leather ear pads was too short for a quality product. It is too early to say how well Sony would last - we will see.
After buying the first headset on Amazon, I got another one for my son. My son absolutely wanted Bose, but after comparing them side by side in a store, and listening to mine, he said, I still like Bose, but I recognize that Sony is better in all respects... So we got him Sony from a local store.
The only frustrating part is that Amazon has dropped the price by $50 after I bought both pairs! What a bummer - but now, Bose is completely not competitive.
The only downside which I found so far... Sony can connect to two Bluetooth devices simultaneously, but it is confusing how the preference works (the one connected last has the higher preference for audio), and there is no easy way to change the preference or even disconnect a specific sound source. You cannot do it in the app. I think Bose is the same way. I also struggled with connecting to my desktop PC for audio and gave up attempts to set up the audio preference correctly. Either I did not figure out how to do it correctly, or something can be improved in the next releases of the App and firmware. I am sure it will be done, eventually.
For what it is worth, competition between suppliers is good - it drives features and quality up and prices down. I hope, Bose will catch up eventually - they missed the opportunity to do it with the 700. Sony 1000XM3 remains the best product in this class for second year in a row.
