I have used the Jabra BT 250 that came with my old 650 and I I never had any issues hearing or other hearing me. I like the H700 as well though I am used to the "in the ear" type and I hear better that way. Just a preference. The H700 has some sort of noise reduction built in, so it is worlds aprt from the H850 which is crap. The best headset to date has been the in the ear H9MiniBlue. A bit pricey but I can hear great and others say I am clear. You have to like in the ear since it is "IN THE EAR"
