Unfortunately, only 1 BT headset can be used at a time.

So you would need 2x Logilink BT0024.

But the device works very, very well. I am very satisfied with it!

Thank you very much for the valued answers. In the meantime, I searched further and found a product from Avantree, the Priva II. I bought this yesterday and have already tested it: it works perfectly with 2 headphones!

I can fully confirm Pierre_koever's comment. Unfortunately, I also have no alternative solution for 2 headphones.
