Summary: I have used the Motorola H790 Bluetooth for years. This is my second one. With the first one, the speaker went out after 4 years, so I searched hi and low to find another one. It was the only one that was small enough to stay in my ears. Call quality is great. I must admit, I don't want any others.
Summary: as far as souund quality goes and crispness, you cant beat it. I have had no issues with. the battery power seems to last quite a long time. My only issue is I have 2 phones. The h721 thru the H730 easily connects to 2 phones wne opening. This one only allows you to connect to one at a time.
