I actually owned one for 3 months and used it with my SonyEricsson T68i. When I upgraded my phone to a Nokia 3650 and discovered that the original version did not work, I called Jabra to complain. Jabra advised me to send them the headset and they sent me a new version. I've tried the SonyEricsson and Motorola B-tooth headsets. The Jabra is the best and least expensive.
