Just a quick suggestion ... Most Urgent !!

My A4 tech wireless headphone got broken but A4-Tech USB Bluetooth receiver is working fine. Right now my system is connected that USB with the name of "A4tech wireless headset RH-10".

My question is that can i use this receiver to connect other headphones to my pc other than A4tech ones ??

Since it is a Bluetooth receiver, it should work with other Bluetooth devices provided it meets the Bluetooth version requirement of each device.
