Does the noise canceling function only work when it is hard wired?

No. It works regardless. If you really want to great sounding headphones, check out Sennheiser RS 170 Digital Wireless Headphone with Dynamic Bass and Surround Sound. I have both of these headphones and the Sennheisers are fantastic.

Not a good buy. Does not measure up to claims. Had problems only a few days after I received them. Noise canceling did not work, soon they would not work at all. Sent them back. Bad purchase, bad experience.

I had a similar problem with a different set and the issue was a defective jack, causing the same signal in phase opposition to be sent to both ears. It sounded almost ok without noise cancellation (no stereo effect though) but when I turned on active noise cancellation the sound would go out. If you still hear faint sound when you turn NC on, it could be your problem. If the sound goes completely off, there is something wrong with the headphones (or the battery is dead)

I have noticed this behavior before, it is entirely normal for any (if not all) headphones that use active noise cancellation. Generally, the cancellation sound is unnoticeable or very faint (and goes away with music, speaking, etc...). I have noticed that while rare (for me) the low-grade noise that you hear from the NC is turned on can raise in pitch slightly. Moving to a different part of the building or even room can help if this occurs.

Not sure, but my intuition is that it should, provided of course that you turn on the noise canceling button. My experience on planes is that you have to turn on the noise cancellation (battery powered in the earmuff) in order to reduce the drone of engines. When watching movies on planes, you're able to turn the speaker volume down several notches provided you've activated noise cancellation.

It's not made to cancel noise, but it works as well as you'd expect if you have your music turned up. However, if you want to completely cancel noise, I'd suggest looking elsewhere.Also, make sure that's actually legal where you are, if you're the driver. Here's a fun map to help you check!http://img.gawkerassets.com/post/17/2012/04/infograpgic_final_2.jpg

It's not a noise canceling device, but since it's used with an earplug, outside noise is naturally blocked out. I use it with an acrylic molded earpiece. Works great.

No. It isn't specifically designed for noise canceling, but it physically blocks some noise.

I do not think that is true. If they do cancel noise, I have not noticed it. Still great headphones, but I would not say they are noise cancelling.

If my husband has the stereo too loud in the next room I can still hear the bass tones. This machine reduces noise but doesn't block out noise. I live on a busy street and it greatly reduces street noises.

I haven't tried this. But according to the instructions, turning on the amp (bass boost) turns off the noise cancellation.

The pair of head phones do not have noise canceling. I could hear the television from wearing it, but if you are listening to anything, the surround sound can help in a way.

It can block out the majority of noise in loud environments, however noise canceling headphones can end up being louder than some quiet environments. An audible hiss is apparent when it is super quiet. These can be used without a device attached, but the hiss will become noticeable. They will work with any audio device that has a headphone jack. I found the full review of these at "The Wirecutter" very helpful.

No, no volume control on the wire, just the switch to turn on or off the noise-cancelling. Perhaps it's worth pointing out that the volume DOES increase when you turn on noise cancelling, since that also turns on the mini amp which boosts and processes the sound signal.

A) this does not have active noise cancelling. b) yes, if you plug the cord in it does not use the battery powering the bluetooth connection. so if your battery dies for wireless usage, you can always switch to traditional analog input.

Yes, as long as the built-in battery is juice left, it is active noise-cancelling.

The noise cancellation is great but does not block all noises. If you are around a loud area with children or a high traffic area you will still hear some noise but not a great amount.

its not noise canceling, its volume control. it limits how loud the headphone volume can get to avoid eardrum damage in kids
