Query: Not durable

I get good voice reports from those on the other end of the call, so the microphone itself is of good quality. I do like having the volume control on the line -- that is very convenient.That said, this headset is not long-lasting. With enough rotations of the microphone swivel, the "teeth" eventually will eventually wear and file to engage, making the microphone flop straight down. It's not a bad headset for the money, but it is not very durable.
