Clear recommendation is really good.

Setup and operation are absolutely stessfrei. The digital output is better than analog, and analog is not bad either. Digital sound is clear and neutral balanced. Analog stands out the bass and the sound is full and center-weighted.

Unfortunately I have no APTX source, but with my old Sony cell phone and MP3's that are usually created with VBR and 192 KB is sounding quite good. Slightly rounder than CD in direct comparison, not quite as clear and dynamic, but the losses fall not necessarily immediately or without comparison.

The striking range specification of 20m is for a receiver (!) Me senseless and heard in this form into the mythical realm of marketing. However, it comes with me only drop outs when I leave the room into the next room and a wall comes into play. That would be me with wall then 6m. Without wall I can confirm 7m as a completely trouble-free. The room is simply no longer.
