Sony iPad/iPhone/iPod Noise-Cancelling Headphones

I bought these 6+ months ago for use at the office and on travel. I primarily looked for a good set for the price that has noise cancellation and covered my ears so i could turn it up a bit and enjoy some rock without bothering anyone else. These have so far exceeded my expectations. I have used them a lot in an office environment along with on a few airplanes without any issues. I don't use the noise cancellation in the office but it works well on the plane. The battery lasts about 10-12 solid hours on one AAA battery. The ear pieces are comfortable, I have been known to wear them for 4+ hours without a break. They block a good amount of the sound from escaping so I can play the music to a good level without bothering my neighbor at work. The sound quality is just fine as well for me. I'm not a savvy music critic that can (or care to) decipher quality between different headphones. As are as aesthetics... they look nice. Their look was the last thing I cared about when I was shopping around. Overall, these have done more than I needed and so far they continue to work without any issues. I will be sure to update this review as I use these more.
