The best noise cancellation circuitry on the market; Rich bass response and crisp highs; Comfortable, secure fit; Works in passive mode

Noise-cancelling in-canal earphones have been far less popular and common than the on-ear and over-ear ear noise cancelling full-size headphones, like Bose's QuietComfort 15($599.99 at Amazon). With the QuietComfort 20, Bose aims to change this. The $299.95 (direct) in-ear pair is offered in two varieties—the QuietComfort 20, intended for use with Android, BlackBerry, and Windows phones, and the QuietComfort 20i, intended for iPhone, iPads, and iPods. Bose hasn't eliminated the inline battery and circuitry compartment that is essential to an in-ear noise cancelling pair, but it is now quite thin and far less cumbersome. The real victory here, though, is the noise cancellation itself—it's by the far the most advanced, flexible noise cancellation we've ever experienced, and that alone would earn it our Editors' Choice award. The audio performance isn't for audiophiles seeking flat response, but the QC20 packs a full, rich low-end and crisp highs that work well with pop, rock, and mo...

The Bose QuietComfort 20 is a giant leap forward for noise cancellation earphones, and easily the most effective pair we have tested thus far.

This review could be as simple as this: "If you're willing to spend $300 on in-ear headphones, then buy the Bose QuietComfort 20 headphones." Of course, the world of in-ear headphones is far more complicated than that. Walk into any electronics store and your choices are daunting.

Bose's noise-cancelling headphones are the best on the market but imagine having that technology in a pair of earphones. No need to imagine – they've done it. The new Quiet Comfort 20 (QC20) acoustic noise-cancelling in-ear headphones deliver the same quality and noise isolation as the regular Bose...

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.

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.

You don't hear sound other than your music unless you want to

Nothing

Noise-cancelling headphones have been the top choice of frequent fliers for years, but their transition to the world of earbuds has been rather slow. To some extent this is not surprising - an active noise cancellation system requires its own power as well as bulk that does not lend itself to...

Unparalleled comfort; Superlative noise cancellation; Innovative ear tip design; Good battery backup; Works sans battery as well; Alert Mode comes handy

Prone to excessive wind noise; Wrongly placed mic; Build and sound quality could have been better for the price

Silence is golden (and expensive, too).
