Are these noise canceling? Do they require batteries?

these are not active noise cancelling headphones, and are powered by the headphone cable, so no batteries required. being a closed back headphone, they do offer passive noise reduction, which is basically the muffling or muting of outside noise by nature of their closed ear cups. but if you want true active noise reduction, these are not for you.

Yes it does. They're battery powered. So just switch it on, and it will do its job. However, I dont think this would be a good choice if you are not planning to play audio through them. They reproduce audio fantastically, but their noise cancelling ability is just so so.

These are noise isolation and they don't require any batteries and I had them for over 5 months and I think there one of the best earbuds out there and there not overprise. I recommend them

No. Noise-canceling headphones cost substantially more than these. However, I find that the construction of the headphones does a great deal to minimize external sounds.

They don't. These are not noise-cancelling headphones, they're just closed. Sound wise they're way better though.

I don't think they are considered noise cancelling but they do a good job of keeping out the noise. For the price point they do a pretty good job not perfect but better than average.

To the best of my knowledge, the headphones do not require batteries. These are NOT wireless headphones, they are corded headphone that plug into a jack on your iPod etc. From the stock photo, they might look wireless, but they are wired.

Yes. It's true they aren't noise canceling, but they do a pretty good job as far as I can tell. My parents complain that I can't hear them calling if I have them on, so that gives you some idea :-)

No they do not have active noise cancelation. But they do a pretty good job of blocking noise anyways.

Yes, they take one AAA battery. They should be switched "off" when not in use to preserve the battery by sliding the yellow switch on the side. They are still functional when the battery is dead; the noise reduction feature will not work, though. Hope this helps :)

Yes, but must be powered on for them to work. There is no "pass -thru" use without noise cancelling. They work fairly well.

It isn't technically noise canceling considering there's no need for batteries. However, the sound isolation is similar to noise canceling due to the design of the cups. They are really great headphones and keep out most sounds. I use them all the time. Plenty of times my girlfriend has asked for favors that I never heard because these headphones are so boss.

They do not. They are noise isolating, but not active noise canceling, if that's what you're wondering about.

Yes, they work without batteries, you just won't have any noise cancelling.

They arent noise canceling but the ear cups do a good job of blocking out background noise. I've only used these in an office environment and they did well blocking out some ambient and background noise but again they do not have NC technology.

They do not. However, the way they plug into your ear combined with the base renders noise cancelling unnecessary. I live in San Francisco, a city were noise pollution is constant and never ending. When I take walks, abrasive traffic unruly children, dogs, skate boarders, construction- goes almost unnoticed.

Neither! These are passive headphones (They do not have an internal amp). They simply reproduce the sound signal sent from the sound circuitry of the metal detector they are attached to. Nothing is amplified, so no batteries are needed.
