Hi, I am having the same problems with "white noise" and "echoing", after numerous calls to Orange (with no joy), I then contacted HTC who informed me that the HTC Sensation uses Bluetooth Version 3, I have used the Jabra BT500v Bluetooth Headset version 2 successfully with my last HTC HD, it now seems that we the customer MUST TEST AND BUY these new expensive headsets
completely at our own risk, come on HTC... SURELY... YOU HAVE DONE ALL THE TESTS FIRST? (Does not look like they have to me) as they will not GUARANTEE and CAN NOT even reccomend a Bluetooth Version 3 headset that
MAY WORK. I drive for a living and the Bluetooth element of this handset is one of the most important features that I REALLY NEED! Needless to say I am very dissapointed with BOTH Orange and HTC for putting out a handset that has not been tested PROPERLY.
