The mic is light and comfortable. I decided that, for me, the single ear mount is not quite stable enough, so I bought the dual ear mount which is very stable. And switching the mount was easy. As for the sound, well, it sounds like me. I can sing very loudly, and I've heard no problems with distortion. Feedback rejection seems to be very good. I've not had the mic for long, but I've noticed no problems with plosives or wind noise.
Before buying this mic I bought a couple of other, less expensive, head-worn mics. I returned them. Finally I decided to try the expensive mic, since I know that Sweetwater has a great return policy. I'm sold. I could not go back at this point. If I buy a spare, the dual-ear version of this mic is the one I'll buy -- after I save up for it.
I'm using the mic with a Line 6 XD-V55 wireless system. Works great.
