Summary: Do product designers actually test their products before they sell them? I bought these to wear at work because I have an IPOD and move around a lot. The noise-cancelling box weighs too much and keeps pulling at the headphones, even when tucked in my shirt. Took them off after 15 minutes of trying my best to like them. These are going back to the store!
Summary: I Think they are excellent headphones. They sound good with and without the noise cancellation. For a young adult my age they are pretty expensive, when you don't have a job. It was a risk to buy them because a lot of things can happen, but i'm glad i got them because they sound HQ. Usually headphones ranger in the frequency from 20 - 20. These Range in a frequency of 20 - 22. They help make you hear things you haven't heard before in a song.
Pros: Noise cancellation tends to be pretty good with these things. I wound up missing a couple of calls while I had them on. Audio quality is pretty good.
Cons: These were not comfortable AT ALL. I had to take breaks from having them on my head. I haven't had them for a week and the right ear crapped out on me. The noise cancellation switch tends to be a bit cumbersome when there are batteries in them. I'm a little confused as to why it's necessary in the first place.
Summary: These are cheap, junky headphones in a prettier package. I could tell the noise cancelling function was doing something, but not enough to make a difference or enough to tolerate the battery pack dangling and pulling on the cord. The battery pack with batteries weighs almost as much as the headphones themselves. It actually muffles the higher tones of the sound source and sounded slightly better turned off. But not that the sound is all that great anyway.
