After reading many refahrungsberichte with MP3 players I have chosen for this device. The sound is good with my Denon inear of headphones. Operation is simple and does not need a manual. Here the price and performance because even a SD slot is available. I'm very satisfied. Especially the volume has convinced me. In more expensive Palyern the volume is throttled so that a player does not really make sense and Kei sd slot. So buy recommendation.
