- Forget "EcoExtreme 2" from your device's Bluetooth list and try pairing again.
- Turn both the speaker and your device off and on again.
7.3 Poor Sound Quality or No Audio
- Check the volume levels on both the speaker and your connected device.
- Ensure the speaker is not submerged in water if sound quality is muffled (though it is waterproof, sound transmission is affected underwater).
