New BT250 synced easily and works ok though it does add a bit of static to the audio, and I haven't seen the expected range. Interesting to me to note how location of phone changes audio, now orientation of phone to BT250 now impacts audio quality. Line the stars up and everything works fine, but if you're not careful where the phone is placed, or the relationship of the phone to the 250 and quality degrades fast.

HOWEVER I must add that the BT250 is the difference between this being an adequate phone and not. I'm on my second 6315 (audio quality and dropped calls on first). Holding the 6315 to ones ear is not fun, nor is carrying the wired headset and having to quickly extract and untangle for those unexpected calls. Being able to stick the 6315 in the pocket and just exposing the 250 (grabbing and answering via the device offhook button) is a huge difference. I was near returning the second one and reverting to 2 devices, but not now. HP should include the 250 as part of the package, can't say enough how much more usable this makes it.

UPDATE - I *do* have to reset the darn thing too often
As stated by others, I'm finding that I can't just leave the headset connected via bluetooth and expect it to work. So I either have to leave BT off on the 6315 and headset, and turn both on to answer the phone, use the brick against my head, or answer it and ask the caller to hold while I "enable" my headset.

Not happy with this solution. HP needs to fix some bugs in their bluetooth implementation?
