Summary: I've had these for about a week and they stopped working properly. If I jiggle the wire a little bit, sometimes I can get them to pick up my voice...but for the most part, the recording quality is not-so-good once I get them to start working again.
Excerpt: I am learning German through a software program with voice recognition and didn't realize it came with headphones so I bought these. They're very comfortable to wear for extended periods. I thought there was a problem at first but I realized it was on microphone mute. My only minor issue is that the mute button seems to be very sensitive and I check it periodically but overall I'm very happy with this product.
