Mine works fine... just upgraded from my 5th 6035. It worked great on it and works as well on my 'new to me" 7135. It does require the use of a dongle since the phone it self isn't BT capable. FYI, you need to keep both the headset and the dongle well charged, weak charge = low volume. I got mine off eBay for about $60.00. Headset wears well, very comfortable.
