CSR8675 Bluetooth v5.0 Wireless Digital Receiver coaxial optical digital Audio Output

Not bad, No external triggers or sounds. Works with Ipad air 1gen at a distance of 10 meters even when leaving the building. But even more interesting is that with the iPhone SE 2020 it works without problems for 20 meters and after leaving the building. But It costs not cheap 30eur but I think it is worth it.
