The great thing about this device is the comfort is great, the multi pairing between devices is convenient to switch between devices. Negative points, sound signature is just OK for me, bass was soft and noise cancelling just didn't do it for me - 3 elements that I feel the sony wh-1000xm3 did much better. Overall if you prefer the comfort and like the sound profile of the Bose, go for it; if you prefer top notch noise cancelling, go with Sony.

The title says it all. This is the best pair of noise cancelling headphones that you can currently buy. Been using it everyday and it is still going strong after a year. Put them on and your daily commute and plane journey becomes a musical paradise. Sound quality wise, it is very balanced with good amount of bass and clarity. Battery life is just as quoted at 20 hours and you never need to worry about charging it.

Absolutely love these headphones. I originally bought them to take to the gym. Whilst I know they aren't sweat-proof I love the fact that I can swap out the ear pads if they are damaged. No sweat makes it's way to the inside of the earpiece which is great. the sound is amazing and the Noise-canceling fantastic. I no longer have to listen to others in the gym or when i go for a walk etc. Worth every cent
Battery lasts ages between charges and I can go over 2 weeks and only use half.

Fantastic product.
So easy to use. Noise canceling option really works, had a great sleep on an overnight to Hawaii.
Sound quality is excellent.
Best birthday present ever.
Charging was easy.

I bought these for travel. Screaming babies on flights will never bother me again!
I use these headphones to listen to all sorts of genres, they produce clear cut sounds, and emphasize the high and lows of each track.

I love them. Great customer service and good value for money. My favourite feature is the ability to speak without having cables around. The only thing I found is that is best not to use them when walking around busy areas as they block some of the noises . But on planes they are amazing

After 2 years of using the headphones, the headphones no longer work. - speaking to bose they were not able to offer any repair option and the only option given was to purchase a new pair.
After one year the earpads started flaking and leaving black foam everywhere.
Disappointing to see this level of quality from what is meant to be a premium product.

Ear pads break apart after about 1yr of use leaving small pieces of black rubber. The paint on the ear piece cover scratches off way too easily also. For the price I am disappointed with the overall performance. Not sure why people rave about these.

I mostly listen to hip hop and upbeat music with a lot of bass, these headphones really made listening to my music much better! They might be pricey but it’s so worth it! The noise cancelling feature comes handy when you really want to get in the zone with no distraction.

I travel a lot on flights and seen most frequent fliers uses this Bose QC 35II head phone. I found them comfortable on long journey, good sound quality listening to inflight movies and audio books with great noise canceling on planes. Long battery life. Not too bulky unlike other NC headphone brands.
I would recommend this especially if you can pick one up under $350. They feel well built and look great in my opinion.

I have tried many different noise cancelling headphones and these out perform all others. Very comfortable to wear, which is not often the case if you wear glasses. Sound quality is excellent. I travel frequently and would not get on a plane without them. Well worth the money.

These headphones have been great - i've had them for 2 years and they've had a lot of use with travel for work. The audio is really good, and the noise cancellation. The charging is quick, and the battery still lasts a really long time.

They're having a problem with Windows 10 and timing out while using them for conference calls - and the microphone picks up too much ambient noise. Fingers crossed these issues can be resolved... but I really like them.

My husband has the Sony - and I would get those as my next purchase... but these have served me well.

I use this headphone for my gym to listen music. It is very comfortable and i can use it for 2-3 hours without any problem. It's sound quality is better than other headphone i have used.

Perfect headphones for work-travel-casual or to just put on when you have annoying co-workers.
Best part is sound, seamless connection.
You will enjoy your long flights :d :d :d :d

I listen to music all the time through these headphones and they are exceptionally comfortable and have amazing sound quality!
Originally brought to take travelling with me which I wore for over 20hours flying and did not get uncomfortable once whilst wearing them at all!!

The bass is not as good as the sony headphone but it is way more comfortable. I can honestly wear these for as long as I want without hurting my ears but the sonys only take a couple of hours to get uncomfortable. The sound is really good!
