Review on MP3 player DIGMA Z4 16GB 16 GB, Bluetooth, black/grey by Minoru Masuda ᠌

You can disregard this evaluation entirely if you do not have a use for Bluetuth. When bluetooth headphones are connected, player functions such as equalizer and fast playback become unavailable. Additionally, not all declared file formats will be available; for instance, you will not be able to play ogg files. When listening to music through bluetooth, the wheezing at high frequencies (or bounce, I don't know how to say it more accurately) is the worst thing that can happen! You can somehow put up with this, but the worst thing is the bounce! If the membrane in the headphones is damaged or if the coil has become disconnected from the membrane, you will notice an effect that is analogous to this one even if you use the cheapest headphones possible. In the beginning, I made a mistake with the headphones, but the issue has not changed with other headphones, and the headphones function normally with other electronic devices. If you connect the headphones to your device with a cable, then you won't have any further issues. The consensus among those who tested the player and listened to it is that it does indeed have a bounce. Even those who chose to ignore it saw that there was something off with the way the sound was coming out. Both the ScullCandy Hesh 3 and the Sennheiser HD 440 BT headphones were used during the testing.
