Query: It just works

I have been using the HS850 for the better part of 2008 and have found it to be a competent little unit. It pairs quite nicely with my Motorola i880 that was assigned by my employer. I find the volume level to be good, though not outstanding. I can hear the other party quite clearly and have had no complaints going in the other direction.The HS850 that I got from Amazon came with a charger and minimal instructions, but I had no issues. After being plugged in for one overnight cycle it was ready to go. The fact that the mike boom also acts as an on/off switch is great, as it tends to conserve battery life. Are there better units on the market ? Most likely. But I feel that I've gotten some decent value out of this handy headset from Motorola.
