Reset your product.

Much like rebooting a smartphone, your product might need to be reset on occasion to correct minor issues. For more info, see Resetting your product.

Try a different app.

If the issue only occurs with a particular app, it is likely related to the app or app settings.

Reboot the Bluetooth® device.

Electronics might need to be reset on occassion to correct minor issues. This is typically done by shutting down the device, then powering it on again.

Check the EQ settings on your Bluetooth® device.

The EQ settings of your Bluetooth device can affect sound. On the device, try setting the EQ to "off" or "flat" and disabling any other sound playback adjustments (i.e. loudness, compression, reverb, etc.). These settings are commonly found in the device's audio settings or in the settings of the app being used to play audio.

If connecting to a Windows computer via Bluetooth®, be sure the Stereo audio profile is selected.

On your Windows computer, click the speaker icon In the lower-right to view the volume slider. Click the ^ above the volume slider to view a list of available audio devices. (Tip: If your Bluetooth product is not connected, the ^ may not appear.) Your product will appear twice: once with Stereo or A2DP next to it and once with Hands-Free or HSP next to it. For full-range audio quality, select the Stereo listing.

Be sure your product is within 33 feet (10 meters) of the Bluetooth® device.

Bluetooth range is about 33' (10 m). This range can be reduced by obstacles (i.e. walls, doors, pockets, nearby Bluetooth devices, etc.). Try moving the device and product closer together.
