If device fails to turn on or won't charge at all.

If the device will not turn on, try to charge it at least for 3 to 4 hours using a USB to Micro USB plug to your laptop or PC. Remember Battery will last up to 4 hours when connected wireless and up to 12 hours when connected through Aux-in audio jack.

Jam

Charging

If the devices fails to charge, try a different USB port in your laptop or PC. If the problems continues try a different micro USB cord.

Bluetooth Connection Issue

If the device fails to connect with other devices via Bluetooth.

Connections

To begin with, make sure you are using the right devices that can connect to the HMDX JAM wireless. If so, then turn off both devices, wait 15 seconds, turn both back on and make sure that the lights on the HMDX Jam are flashing. Ensure device is showing that it is searching for a host. Also, make sure your other device's Bluetooth is on and is searching.

Adjusting Volume Issue

The loudness of the audio output does not increase or decrease when volume button is pushed.

Max Volume

When at maximum volume, the sound fills the room; but the audio tends to be to harsh to the ears. The speakers perform the best at medium volume.

When Connecting to Multiple Devices

When the speaker is connected to more than one device, the sound is noticeably improved because the devices pick up mid and lower frequency sounds. However adjusting the volume on one speaker (when paired) doesn't change the volume of the other.

Device Slides Off Surfaces

Speaker does not stay placed in one position on a surface. Device slides off of slightly inclined surfaces or shifts position very easily.

Rubber Base

This may be due to the wear and tear of the rubber base of the speaker. The base may be worn out and has lost its grip to stay placed in one position on a surface. If you want to restore the sturdiness of the speaker you need to replace the rubber base cover. This guide shows you how.

Factory Reset

Speaker is not pairing with Bluetooth devices or is showing that it is paired but is not playing music from Bluetooth device.
