Top functionality, sound unfortunately a sober flop

Unfortunately, I had to return the good piece again, the functions and the processing for such a small device has to convince me quite the sound but unfortunately not.
No matter what setting the predefined genres selecting or on the personal attitude in the equalizer, unfortunately, the radio listening still relatively dull on. No clean highs / mids or lows. At low volume the bass lacks completely and rises from level 5-6 abruptly. The mids and highs in this stage also rise significantly.
Everything worked perfectly, device problems, operation and also play music via USB stick was consistently easy.
Anyone looking for a simple radio for the kitchen and not so high expectations for the Kland provides will be well served with the Medion. All who love their music to hear sound in fair HiFi, should look elsewhere. I think somehow no Internet radio, which works flawlessly. Either server problems, fundamentally bad service, too large, inappropriate equipment or just consistently poor sound.
I previously had a Logitech UE radio which has a much better sound, this I had, however, because of blatant exchange server problems. Partial days long break because of the Logitech server is unreachable. Thus, this radio was not used during the outages.
