Hi everyone, I spend so many hours reading your reviews that when I saw there wasn't any for the Bose QuietComfort 20i NC, I decided to write my first review ever. So please be kind with me, I'm not a pro (and not a native neither) ;-)     You have to know... ...I'm not a huge fan of Bose products.

Comfort

Low sound quality ; noisy noise canceling mode

At £260, these cans really have to work for their place in your ears, but the good news is they deliver and then some. The Bose QuietComfort 20i provide a solid 16 hour battery life, as well as active noise cancellation.

I use this for work.

Comfortable; Compact; Great Sound

If you're looking for a pair of in-ear headphones to help take the edge off a chaotic commute you'll not find better than the Bose Quiet Comfort 20i. Unlike the bulky over-ear designs the ear buds are lightweight and comfortable and they fit in your pocket instead of needing extra carry-on luggage...

Pocket friendly; Noise cancelling; Comfort

Audio performance; Price

The latest noise cancelling headphones from Bose are light, simple and very good - but they're not exactly inexpensive. In noise cancelling terms, Bose is the premium brand to which others aspire, but they're best known for their full headphone devices.

Supreme comfort and stellar anti-noise make the Bose QuietComfort 20i the noise-canceling buds to beat.

Superb noise cancellation; Extremely comfortable and stable fit; Slim battery pack; Audio plays without power

Expensive; Bulky inline mic/controller; Battery life could be better

These little headphones kill the drone of an airplane as well as my over-the-ear model. But their compact size is what sets them apart - they fit easily in your purse, briefcase, or pocket. The only downside is the price (hence the loss of one star). Highly recommended.

What I like most about these headphones compared to the over-ear type is they are less obtrusive, and lightweight. The sound quality appears to be about the same as the over-ear models.

Comfortable; you can sleep on them; rechargable battery

Sound quality needs improvement

Nice little set of earbuds. Work great, yet Bose has one major flaw that separates these from their over-the-ear sets. That flaw is that you can get either the set for IOS or the set for Android, and neither one has the ability to work on the other.

Noise cancelling; small and travel friendly

You get it for IOS or for Android; and once you've bought it you're stuck to that platform

Battery life is good - 16hrs. Comfortable fit. Insane noise cancelling. Not good for windy conditions (such as running on a windy day). Excellent for planes, airports, etc.

Noise canceling is incredible - especially for consistent background noise like planes; Fit is comfortable

The case that's included is a bit too small - it is a squeeze to get the headphones in there; On a $300 pair of headphones, I'd like to see a more innovative / customized case that helps cut down on tangles
