miklos4 years ago000I already have a Logitec keyboard and mouse that I connect wirelessly via USB (I think they call it a Unifying receiver). Can the headphones be connected to the existing receiver, or do they take up another USB input?

This works with an existing Unify dongle.Show in original language (German)Commentmueller4 years ago000A separate USB dongle is included. However, you can also connect the headset directly to your laptop/PC via Bluetooth - it works just as well for me.Show in original language (German)Comment
