We appreciate the review you've provided us. Here are some troubleshooting steps for us to check your JBL Tune 500 BT: 1. Please try using a different music player and If you're using an equalizer, turn it off. 2. Try using a different source ex. (phone, tablet) to check if the sound quality is the same using a different device. If steps above didn't work you can also reset the headphones: Long Press of volume + and volume - at the same time while the unit is on. Make sure that bluetooth is NOT on and connected to any device. When reseting, LED will blink faster. If the problem persists, you may check your options with the store where you purchased the headphones.
