Hi, I just purchased a pair of QuietPoint Active Noise-Cancelling headphones (ATH-ANC7b). I am using them to reduce exposure to ambient noise in our very busy office, so I just have them turned on with no music playing. They cancel the noise very well, however, I am hearing a constant high-pitched humming noise from the left earpiece. There is occasional noise from the right earpiece, but not as constant (perhaps every 10 or 15 seconds). I am disappointed that noise-cancelling headphones introduce an annoying noise of their own - is this normal? Is there a way to eliminate this?

I know of no other problem like yours. But anything is possible. Any sound coming from the earpiece has to be created BEFORE reaching the driver. You may have a defective pair of phones in my opinion. Sounds like the Noise-Cancelling Circuitry. A/T is very fair when it comes to repairs. If these phones are less then a year they will give you a new pair.
Good Luck!

Answer:Â
Return the headphones,the high pitched sound is indicative of oscillation caused by undamped feedback,something is probably wrong in the noise cancelling network.

Answer:Â
Thank you for your inquiry. What you describe is not normal. One thing to check for is some type of digital interference from a digital device. Try using the headphones in another environment away from your office setting. If the noise is not present you will need to identify what is causing this interference at the office and move away from it. If the noise is still present away from the office then you may have a service issue and will need to contact our service department at (330) 686-2600 option 4.

Answer:Â
I just purchased the ATH-ANC7b and find a big difference in the music balance, level and sound leakage between noise canceling being on or off. When it's off there is much more bass, almost no sound leakage but level is much lower. When on, the music level and leakage go way up, and most of the bass goes away. This is probably a necessary effect of the way noise canceling has to work in a headphone. I can live with this as long as I only use noise canceling when there's enough noise to justify it and leakage won't matter. In a quiet office environment, better to leave it off.
BTW, the ear cushions were supposed to have more room inside than the previous model, but these came with the old style cushion. Also the headband doesn't extend far enough to fit me, and when extended the phones don't fit the carrying case.

Answer:Â
My wife had the Bose noise canceling headphone lost them and borrowed my ATH-ANC7b. I've listend to both and yes the ATH-ANC7b does have better base reproduction than the Boise. To put it another way my wife has no taken my ATH-ANC7b headphones and given me her (now found) Bose headphones. I'll be buying another pair of ATH-ANC7b when I can.

No they are not noise canceling headphones. If you are looking for noise cancelation you may be interested in looking at these: ATH-ANC7b.

Where can I find a replacement cable for my headphones? The diameter of the plug is smaller that most I've found in stores and it needs to slide into the headphone body.
