Maybe try checking if your device is set to an unpleasant audio equalizer setting.
You can change the equalizer setting while listening to your mp3 audio file by pressing the “Options” button (below the Center Select button).
Press Option, then press Option 3X down to “Music EQ”. Then press the Center button.
Try “Normal” or “Pop”. Then press the Center button to select your choice.
In my opinion, the 'Full Treble" setting kinda sounds “delayed” or “distorted”.
Another idea, if you are using the earbuds supplied with the Clip Sport, you may get a richer sound experience by pushing the ear buds a little bit farther into your ear canals.
Maybe report back with your results so more SanDisk Forum members can help you.
