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

They don't come cheap and you can get higher-fidelity sound at the price, but we just can't ignore the fantastic noise cancellation the Bose QuietComfort 20i offer. These some of the best commuter headphones money can buy – and certainly the best in-ear noise cancelling headphones we've tried.

While Bose is at the top of the chart for noise cancelling technology, I couldn't give these headphones 5 stars for the following reasons. 1. When the battery runs out, the sound keeps going (Bonus over QC15) however sound quality is seriously degraded.

A lot of people will think they're overpriced, and they'd be right to think that. But for a certain subset of the headphone-buying population, the QC20s are an excellent product that's strongly worth considering.

The Bose QuietComfort 20 and 20i are compact in-ear headphones that sound good, are very comfortable to wear, and offer surprisingly impressive noise cancellation; The noise cancellation is powered by an integrated rechargeable lithium battery that delivers up to 16 hours of battery life

Expensive; they don't sound as good as many competing in-ear headphones in this price range; rechargeable battery isn't replaceable

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

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

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

They work great except there is no song forward ability when using a Samsung note 2 phone, there is only start and pause capability. It is amazing how they cancel out things like airplane noise, bus engine noise and lawn mower noise.

I got these headphones because the AC in my room was too loud at night. They took a bit to get used to, but I love them. At the price I paid I was very worried I wouldn't like them or they wouldn't work, but they're great.

Comfortable

Poor Value; Too Much Ambient Noise

Does exactly what it says noise cancelling is brilliant sound is excellent

Nothing yet only had them since Christmas
