Query: Great electronics, poor electronics.

The sound quality was excellent, but the earpiece is flimsy and irreplacable: terrific electrical engineering, poor mechanical engineering.I loved it when it wasn't broken. Even wind didn't seem to bother the headset much. The voice quality was great on transmission and reception. But the earpiece is incredibly flimsy and can't be replaced. I got a new headset the first time on warranty. The second time it broke I could have gotten a free replacement again but I didn't want the hassle. I have a Scala now that I've been using for months and I'm very happy with it, even though the sound and wind-immunity doesn't measure up to the Logitech.
