Query: THESE ARE AWFUL!

The sound quality is fine and the range is okay, but the headphones are so poorly constructed that I have been through two pairs in 6 months. I was extremely careful with the second pair and they just broke this morning after only 3 months of use. The joints that hold the the phones are weak and plastic. DON'T DO IT! These won't last.
