The headphones' noise-canceling circuit senses outside noise using tiny, built-in microphones and sends an equal-but-opposite canceling signal to the headphone drivers, effectively blocking solid-state (continuous) noise from 40 to 1,500 Hz. It's especially effective on noises like air-conditioning systems, freeway rumble, and airplane engines (from a passenger's perspective).
The switchable noise-canceling circuitry runs for approximately 30 hours on a single AA alkaline battery (with battery housing located just above the right earphone). When noise canceling is off, the headphones continue to function for standard music listening (and with slightly better sound quality). The headphones' neodymium-magnet diaphragms deliver powerful sound.
The HP-CN6 features a mini-jack for connecting to portable CD players and digital audio players, but it also includes a larger jack adapter for home stereo receivers and a dual jack for plugging into airplane seats, enabling you to enjoy the in-flight movie in peace and quiet.

These were hand-me downs from my brother-in-law who basically didn't use them all that much, but I have to tell you, I've had them for about 3 years now and still work as they did... Read morePublished on December 23, 2008 by Evey
These headphones have been very useful. The only time they make a little hiss noise is when the battery is about to die. Other than that I would recommend these headphones.Published on March 16, 2008 by Amazon Customer
I've had my HP-CN6's for going on 3 years now. On plane trips they're great at sound reduction. It does indeed reduce ambient noise by 70%. Read morePublished on March 25, 2007 by R. Reed
Save your hard earned $$$
It's simple "it doesn't work" the best ones I've tried on were the Boss, but they're very expensive. Read more
I bought these two or three months ago after a colleague told me that noise-cancelling headphones are very nice when you are on the plane for hours and hours. Read more
I agree with Watt mentioning there was a hiss..and I think its low-noise cancelling effect is good, not for voices at times.
Music quality was heavy in bass. Read more
When I first received my head phones I though they were ok at best, the sound quality was decent but the head strap appears bulky when wearing. Read morePublished on January 15, 2006 by Duff
