Best BT Headset for Z600??

[garfiled]

I've just ordered a Sony Z600 here in the UK. I need to know which would be the best BT headset for it. It will be used mainly in the car as the law has changed on use of Mobiles in cars in the UK. I will probably be wearing glasses most of the time (don't know if that will effect the future choice). Currently looking at the SE sets as i want to keep all the functions of the Z600,thought a dedicated set from SE would be best bet. Let me know if otherwise!!
Just one last thing. Do BT sets ring or beep? Do they all support V/dialling and do the copy the ring of the phone. ie; for different profile rings-or just a standard tone or bleep?

Thanks all
