Awesome Noise Canceling Headphones
347587
The head phones are awesome and reduce and astonishing amount of back ground noise (street and subway). You can still hear people talking a bit but it's very muted and greatly reduced from having no headphones on. I am very pleased with the sound quality, especially with the bass, but that's because I'd been wearing in ear headphones for the last several months. Basically the sound quality is more than passable.

I have an exceptionally large head and they fit better than I expected. They do make my ears very warm, but that's expected. I'm also not sure they'd stay in place if I were to exercise, but walking 10 blocks and riding the metro for 45 minutes, they are great.

These headphones are amazing. Noise canceling feature works very well, and they stay in my ears. They are very easy to untangle and they are super durable.

Wow.  I am in love with these headphones.  They sound better than my $100+ beats wireless headphones.  I am going to order a second pair.  They are so comfortable and are noise cancelling!

I love these headphones! They are very soft and comfy to wear but provide great sound quality. I have missed a few airport and overheard announcements though when the noise cancelling feature is on, because they work very well!

I bought these headphones for work and because I have tinnitus (ringing in my ears). I wanted good noise cancellation, because that lets me listen to music at a lower volume, which reduces the risk of hearing damage.

The noise cancellation on these headphones is amazing, better than anything I've ever experienced. Put them on and turn noise cancellation on, and it's like being in space. You can almost feel the vacuum. It's kind of eery, actually.

They're also the most comfortable headphones I've ever owned. I could wear them for hours and hardly feel them.

I'm not the biggest audiophile in the world, so I'm not really well qualified to speak to audio quality. I'll just say that the audio quality is more than good enough for my needs.

Great headphones for the price! My husband has a pair of Bose Noise Cancelling headphones and to be honest, these sit better on my head and ear. Much more comfortable. The sound is really good as well! As far as the noise cancelling function, they do the job quite well. The room sound (family talking) was very much muted. I don't really think you could do much better for the price!

They're very comfortable, and the noise cancelling feature works great! For the price, they're the best I've found (I paid about $125 for these headphones). So, here are the 'Good and Not-So-Goods' about these headphones:

Good:
1. Great noise cancelling! It advertises 85% noise reduction, and that seems about right. Remember, noise cancelling works best on sounds that are consistent, such as an airplane/car engine, a fan, etc. While it is true that you can hear people talking (though dimly) when the music is off and noise cancelling is on with these headphones, that is actually pretty normal. If you don't want to hear people talking (you want quiet in a cafeteria, for example), take a look at noise-suppression headphones. These headphones mask ambient noise - they don't try to suppress it.
2. Sound quality is great with the noise cancelling feature on. Great high and low range.
3. Headphones can be used for listening even when the battery dies.
4. Very comfortable to wear. The around-the-ear design makes these headphones very comfortable and something you can wear hours at a time without discomfort.
5. Carrying case is hard, durable, and has enough room for your I-Pod, Cell Phone, etc.

Not-so-Good:
1. Sound quality without the noise cancelling feature on is greatly diminished. Both high and low range are muddled. Mid-range works about the same.
2. Noise leak occurs. My wife comments she can hear my music when she's sitting beside me and I'm 'Rocking out.'

So, you'll love these headphones as I do if you take an extra battery with you and keep the volume level down. Plus, you'll save your hearing. You might also find that you experience less Jet-lag, as you don't have to hear the drone of the engines while you're flying!

Device is great for canceling out noise too.  When I have it on at low volumes I can easily tune any outside noise.  Fits great and is a lot better sound quality then I expected from bluetooth headphones.  Recommend for anyone as I have wore them for hours with no problems.  Some people may not like the ear covers as they are large but personally I like them.

I loved these headphones so much that I ended up buying two of them, one for me and one for my partner. They seem to be built really well and they fit great and are very comfortable. The do a great job of cancelling external sound/noise and they sound really great. This was an amazing find at a great price!!

These headphones are known to have the best noise cancelling technology. I am happy to say that, they absolutely live up to the hype. Extremely light, comfortable, and great for silencing background noise.
They are great for phone calls, as the microphone is fantastic! People say my voice comes through loud and clear.
They one issue that gets to me, is the cord. The receptacle is set inside of the headphones and is smaller than a standard headphone jack. So, only bose cables for replacement. Also, the connection between the cabke and the jack is pretty flimsy.
I recommend to travelers or anyone in need of some peace and quiet. These are wired, so hopefully that suits your needs too.

Love them! They cancel so much background noise out. I was so happy I got these. Took my ears a little while to get use to them but I use them everyday at work and when I workout.

I really enjoy these headphones. They not only look cool they also have great sound quality. I like that I don't have to crank the volume up. Even at low volume I get clean crisp sound with good base. I wear them around my apartment that can get loud with all neighbors running around but when I turn on the noise canceling feature on its like they all disappear and I just have my music, LOVE IT. Cant complain to much about the comfort... I can wear them about two hours before I notice any strain on my ears. Overall I was happily surprised by the overall quality of the product for such a good price.
