Audio via Bluetooth - 2 headsets at same time?

I must say I'm a bit surprised that I can't seem to find a definitive answer as I would have thought they'd be plenty of people in my position.

I simply want to connect two bluetooth headsets (would they have to be identical?) to my laptop at the same time so that my wife and I can either listen to music or watch movies together.

I've seen a couple of answers on the web stating the Bluesoleil software will do it but they might be just saying that get me to buy the software. There also seems to be a device that you plug into the audio port (3.5mm) although not popular and that's not using the onboard Bluetooth chip.

Obviously this can be done using wired headsets but I just want wireless.

Thanks very much and hope you can help.

One issue to be concered about. Windows only allows one default audio playback device. Thus if "Bluetooth" is set as default audio playback device and it does not support more than one device you can't have another.

However, I see separate Bluetooth devices that will handle more than one headset on the US Amazon site. Same or similar items should be available in the UK.

I had the same problem. Headphones need to be able to properly connect.

Recently, I read an interesting article on this topic. Perhaps this can help you find a solution:
