Whenever I'm on an airplane, as soon as passengers are allowed to use electronics, at least a half-dozen pairs of Bose's Quiet Comfort headphones pop out of carry-on bags. Despite increased competition, Bose's noise-canceling headphones are pretty much the standard for air travel.

Excellent noise-canceling; Aware Mode lets you hear some outside sounds at the touch of a button; Comfortable to wear.

Noise-cancelation can bother some sensitive users

I had bought my husband the Bose® - QuietComfort® 15 Acoustic Noise Cancelling® Headphones as a stocking stuffer for Christmas, and he liked those so...

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

Nothing

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.

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.

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

Just like how Sennheiser downsized the Momentum's experience with the Momentum On-Ear, Bose has done the same with the noise cancellation products - bringing the same feature into an in-ear form factor.

Excellent noise cancellation; In-line battery & circuit compartment is fairly sleek; Adequate bass response; Vocals are handled well; Comfortable tips suit long listening sessions

Not meant for bass addicts; Expensive

Wife did not like the over-ear (hair issues). Sold those and got these and she loves loves them! Great for plane rides, and some (not 100%) help at F1 races. Although they are quieter this year. Anyway, I digress.

These headphones do exactly what you want from them. They are comfortable to wear, easy to handle and do the job. When noise cancelling is switched on they are very effective but control is just as the fingertips so that you can switch back into a safer mode when you need to hear what is around you.

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.
