528 Player Pro Customer Insights

1. The play area at the bottom is also very small and not easy to use.I love this app because it keeps all my music on a high frequency and balanced also it comes with a free radio that has my favorite music like REGGAE24/7!!! You can also switch it to 432hz and it's only 99 cents a month I think I don't remember how much it costed to buy the pro version but it was worth it...Thank you for making such a great app.

2. I use multiple Bluetooth devices for music and don't like to change the EQ bands every time I switch to a different device, so having presets that are saved, synced, and tailored to my devices, would be ideal.

3. hope there is a fix for this.. Update: bug fixed.For some reason the music player all of a sudden replaced my song names with the word unknown so it makes it almost impossible to use it.

4. Fortunately there is a Flac Cue Splitter app that works perfectly until then.I had never heard of or seen anything anywhere about this particular music player and radio station streamer until I came across at today.

5. i decided to get maple player where you can pitch change your music yourself.Love this app, seamlessly converts music and YES it really does make a difference.

6. After the music is paused for a long time and you try to play the currently paused song.

7. With this converter I can listen for hours and FEEL BETTER not worse 🥰Pause, play, forward, and back cannot be operated via corresponding buttons on the Sony SBH54 bluetooth headset device.

8. Most commercial music is broadcasted at 440hz which gives me a headache/earache feeling after an hour or so of listening.

9. Other players are able to play FLAC + CUE as if they are split into tracks and I would like it if 528 Player could do the same.

10. The player from the pull down phone menu becomes unresponsive forcing you to open the player and it choose a new song.

11. same buttons usable with native music app of Xperia XZ.
