Summary: Although the price is high, if you suffer from a hearing loss (as I do) these headphones are a good choice. I connected my headphones to my Yaesu 857D (with a mono adapter in the speaker jack.) I was impressed on how well I was able to hear the audio of the rig. Additionally they are comfortable and really do block out noise.
Summary: I bought these Bose QC 15's for myself, to get some decent sound quality and awesome noise canceling. The sound quality was much better than I expected! If you turn on the headphones, it eliminates 50% of the background noise. Once you turn your music with about 50% volume, it eliminates 95% of the background noise. Once the music is turned up 80% volume and up, 99.9% of the noise is blocked. Just simply amazing!
Summary: I like the Bose QC15, works as advertised, excellent build quality and very comfortable to use. I like the Apple connector allowing control of volume on Apple products. Some complain over the cost and yes there are cheaper out there, but as they say 'you get what you paid for...
Pros: Comfortable, Good Bass, Great Sound, Great with the Apple IPad, Lightweight, Noise canceling is great
Summary: I use it mainly for two occasions: - When I mow the lawn, the mower's noise used to be killing my ear, now I can enjoy whatever audio I like. - When I take flight, it blocks out all the surrounding noise.
Summary: This is my first Bose product. I listened to other headphones that were in the QC15s price range, I'm no audiophile, but these sounded better by leaps and bounds over all the offerings from Monster, and others found at the Apple store. The bass is just right. The bass will rock your ear drums, but it still does it in a clean and tight fashion. The highs are crisp and clear, I hear music totally different now. My favorite part is the noise cancellation.
Summary: Replaced a lost Bose unit with this, newest version. Sound quality and noise reduction are excellent. Also quite comfortable. As I travel by air extensively, noise reduction headset is a must. You can't go wrong with Bose!
Summary: The headphones have good sound when they are fitted over the ear correctly and the noise cancellation works well on airplane noise - both cabin and engine. They are great for traveling but there are better headphones out there for just home use without the noise cancellation.
