Why is my JBL's sound quality poor?

I have been using my JBL for about a year now, and the sound quality seems worse than usual. Is there a way for me to fix it?

ANSWERS:

I rebooted my cell phone and it cleared up. Updated the firmware earlier but to no avail. Try powering off your cell and reboot.

I have found out that Spotify is the issue. I’ve used other platforms and it has run perfectly.
