The H700 was my first blue-tooth headset and I really liked the experience. I drive a Mazda Miata with the top down most of the time, and I can hear great, though wind noise does have some effect on how I come across to others. The mic on My first H700 (all black) quit in August, after using it for about 16 months. After a lot of comparison shopping and research, I was disappointed to see no real alternatives out there except much larger, or in-ear, or less-convenient devices.A couple of things I really like include- flip-boom of/off. I carry it in my pocket and good to know it won't come on accidentally.- easy use for volume, re-dial, hands-free, voice activated calling.- pairs easily with my Cingular 8125 PDA phone.- standard USB cable charging...this is huge. they should essentially outlaw all non-usb connectors for data and power. I have a huge bag full of chargers and accessories for a plethora of phones etc. over the last 11 years or so...I will not buy a phone or bluetooth that uses other than a single usb connector for charging/data connectivity.My new replacement (deep blue and silver) is unfortunately much less snug than the first...I even had the dealer replace it once, with only slight improvement. Thinking about maybe a little fingernail polish on the nubs to try to tighten the ear-piece...You've got to keep the phone fairly close and on the same side as the headset. Works as expected in the car, but if I'm out and about, holding the phone in hand, and shift it to my left hand, very noticeable interference...must be all the tinfoil in my head.
