Query: Big Dissapointment From a Major Recognized Brand.

I've had this for about 8 months, VERY DISSAPOINTED. very low volume, can barely hear callers. Callers can barely hear me. The over the ear style headset doesnt seem to fight tight enough, and if you happen to jerk or move your head very fast, the headset almost flies off. I do also get a little bit of "bluetooth static" MY BIGGEST PROBLEM, is that for some reason this thing randomly places call, when I dont even touch the headset. I'll be drivng along, and my headset starts ringing for no reason. IT constantly did it, and became annoying as I could not shut off the call with the headset, and had to fidget and try and get my cell phone out of my pocket to end the call. I replaced it with a Jabra 250v and absolutely love it. Dont bother with this headset, although its fairly cheap online, as compared to the $80.00 at most retailers, you'll be extremely dissapointed.
