If the speaker’s sound quality is poor, check that it is sufficiently charged, and that all components have been installed correctly. You should also ensure that the speaker is properly connected to your device, whether it be through Bluetooth or one of the several media ports. Try turning the volume up on the speaker’s control panel and see if that helps. If none of the above suggestions work, please reach out to us at support@tzumi.com or 1-855-GO-TZUMI, and an experienced customer support representative will be more than happy to help you.
