Excerpt: The QC 20 is hands down the best Noise Cancelling headphones you can own. I was walking down a noisy street with it one day and upon flicking the power switch to "On," it felt as if all the passing trucks and pedestrians have disappeared into thin air. I looked around me in disbelief as cars and trucks rushed past me in silence, as if I was watching a modern silent film.
Pros: Best Noise Cancellation, Comfortable, Compact, Great Sound, Lightweight
Cons: Bulky Battery, Dust Magnet, No Smart Auto-off
Excerpt: Despite traveling from three to five months out of the year, I have somehow survived over the years without noise-canceling headphones. My travel kit includes a variety of earbuds to listen to music on the go and cheap, disposable, foam earplugs when I just need to mute the noise on a long flight. <br /><br />I have been curious about noise-canceling headphones, though, especially after listening to some Bose demo headphones.
Excerpt: The new QC20i noise canceling in-ear headphones from Bose are quite good. Interestingly they do not need to be inserted deep into the ear in order to effectively cancel ambient sound and perform well musically. When in their carrying case they take up much less room than my QC15 headphones do in theirs yet sound at least as good. USB recharging is a plus, as is the ability to listen to music when the noise canceling circuitry is switched off.
Pros: Comfortable, Compact, Durable, Good Bass, Good Value, Great Sound, Lightweight, Stylish
Excerpt: The in ear phones have an excellent fit and very good sound including noise cancelling. Although not to be compared with full ear headphones their quality exceeds most if not all in ear phones I know.
Pros: Comfortable, Compact, Durable, Good Bass, Great Sound
Summary: I bought these after reading all the positive reviews. However, after trying them for several hours, I took them back to the store. I really don't like that ear plug feeling, and the noise quality is not what you would expect for this price.
Excerpt: I purchased this for airline travel and road trips. They have hands-down the best noise cancelling of any headphones I have tried so far (only second to the $+ pilot headsets), but the sound quality is seriously lacking compared to less-expensive Sennheiser headphones. They do sound good, but when comparing to great sounding headphones of similar price, these sound like throwaways.
Excerpt: The noise cancellation is terrific. I was concerned that they wouldn't stand the test of bus and NYC street noise, but they rock.<br /><br />slightly concerned about the jack that plugs into my iphone/ipad that it may wear out, but so far so good.
Pros: Comfortable, Compact, Good Bass, Good Value, Great Sound, Lightweight, Stylish
