Bose has been working on technology that cancels noise - and in effect, recreates silence - for 35 years. The technology was integrated into its over-ear QuietComfort 25 headphones. Now it has been miniaturised and implanted into more convenient in-ear headphones, the QuietComfort 20.

Excellent overall sound; Active noise cancelling; Long battery life; Comfortable design

Battery brick is intrusive; Expensive

Yes, it's a lot of money for a pair of earbuds, but if you travel a lot especially on airplanes they are great. I can't say the sound quality is in that price range, but it's more than just about the sound. They are lightweight, not bulky like over the ear noise canceling headsets.

First impressions When it comes to home entertainment and even car entertainment I would say that Bose is a brand that most people are aware of. I always thought of them as a premium brand and this wasn't just due to their pricing.

High quality sound; well made; good features

Not for those that like their heavy bass

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

I use this for work.

Comfortable; Compact; Great Sound

It is really hard to find any good headphones that offer such high noise cancellation and yet provide rich sound in such a small form factor and for these facts, the price of ￡259 appears to be justified for the Bose QuietComfort 20i.

Ultimate Noise cancellation Punchy bass Crisp highs Very sensitive speakers Spare earphone tips

Expensive Mid tones can become muddy Not entirely flat response

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.

Noise cancelling technology is even better than ever; much better than my previous over-the-ear style and small for traveling. A must have for flights. I hope the cable is robust coming out of the main unit; being repeatedly shoved into the provided pouch that is barely long enough might run it's...

If you have followed my on Google+ or even Twitter, you probably know my love for Bose' headphones. I've been using the Bose ime2i headphones for about 3-4 years now and have loved them. Usually headphones would last me maybe a year, but these could probably last another 3-4 years.
