i finally managed to pair my Sony ericsson bluetooth headset with ps3.
but when i wanted to use the headset with my phone, i have to pair it again.
then when i want to use it with the ps3 again,
i have to repeat the steps all over again

the headset can only be paired with only one device.

question :

is the ps3 bluetooth headset 2.0 worth it?
how many device can it be paired to?

any other better options?
