I bought this unit because of the classy form factor. A behind-the-ear unit is much better (in my opinion) looking than the floppy, obnoxious over-the-ear units.I used to have the Moto HS810 and lost it somewhere. It was a great headset, everyone could hear me, and it had great battery life... but it was an ugly little bugger.This H605 is gorgeous and I can hear everyone who calls with extreme clarity. Unfortunately, no one can hear me (that seems to be the overriding theme in these reviews). I tried and tried to make this work, but everyone I talk to complains that I am impossible to hear. There is either too much background noise or my voice sounds too distorted to understand. My wife refuses to talk to me when I call her using this headset.So, with much sadness, I am sending it back. Looks like I'll be back to the ugly HS810 or HS850 until someone can invent a decent behind-the-ear headset.
