Which codecs are supported? Unfortunately, you can't see in the current digitec product description whether, for example, "aptX" or "aptX HD" are supported. Is it also correct that only Bluetooth v3.0 (released April 2009!) is supported? Currently, Bluetooth v5.0 would be supported (since mid-2016, in between there would still be v4.0, v4.1 and v4.2).
