I will invest in a set of these, I can listen to music from my TR and answer my calls from my E815!

Just following up with you to see if you have purchased the HT820 headset. Does it work like you expected?
They are great but you have to make sure that all your bluetooth devices are compatible,
Bluetooth 1.2 supporting a2dp is a requirement
Most PDA’s dont have this and not many phones have it.
Works great with skype though!!
And the battery life is good
