I thought with, well for 30 euros you can not expect much, but that's presented here is appalling. The sound is lousy. The heights are too overloaded that doing in your ears hurt. The centers are easy to guess, and the bass is literally non-existent. In principle, the "radio" a overtightened Hochtonverstärker. Because yes hears my 10 Euro MP3 player better at. There are also missing standard features such as bass, treble, fader, balance ... everything can not be set. The radio transmitter does not have a memory, because listening to the radio is to click orgy. Pressing the buttons is also quite noisy and the radio will look even cheaper than it already is. I have it for 10 Euro more, the "Denver 12,517,760" fetched and even then do not expect much but I was pleasantly surprised.
Conclusion: Stay away from this "car radio", unless you have an audible Fequenzbereich below 5 kHz ;-)
