Question about TechniSat USB Bluetooth Adapter

I was not able to connect my JBL HEADSET, I think this will not work with most devices either.

Good day
The adapter does not work on any of my devices. I tried to connect my Technisat with JBL headphones and Logitech keyboard as well as Samsung TV - all without success.
Greetings RM

The USB Bluetooth adapter is plugged into the Technisat and supplies the headphones directly, i.e. not via the TV. I have connected a Beats Solo 3 (also sold in the Apple Store) via Bluetooth. Works perfectly. On my Technisat, a search for Bluetooth devices can be started under Network functions under Headphone connection. It then finds my Beats Solo 3 and connects to it. The TV is left out (I also have a Sony, but it is connected via HDMI). If you set the Technisat sound to mute, the sound via the TV is muted, but the audio via the Bluetooth dongle remains.

I don't know. But with LG TV and JBL it works perfectly!
