I have tried so many brands of BT headsets. Don't understand why SE phones only work well with its own BT headset. Tried the itech on SE W800i but sometimes got disconnected. The HBH-DS970 work so fine with my K800i and M600i. Today, I bought the V-Three BTH9 because of the OLED display ...... too bad it got disconnected with my K800i sometimes! dang!
