I have read through the entire Bluetooth forum and can not find a specific answer. Some say voice dialing may work but aren't sure, others say no.

HS850 - can one use it with the voice signal program? Also the adapter for the euro version, what are y'all referring to, an attachment to the charger of the earpiece?

BTW, I have owned the BT250, the 810 and just ordered the 850. Here are my findings.

BT250 - great fit for the ear, great volume, but the range sucked. I couldn't travel very far or go around corners.

HS810 - felt floppy in the ear, volume wasn't as loud as the Jabra, the range was fantastic, I could go into other rooms, around the corner, etc. When I tried the same with the 250, the 250 was horrible.
