If you only hear sound from one side when using SoundJet R1, it’s usually caused by a loose AUX connection, Bluetooth interference from your phone, or a pairing issue with your earbuds. Checking the connection and resetting the devices typically resolves the problem.

Quick Fix

Try the following steps in order:

1.  Check the physical connection

● Make sure the SoundJet R1 is fully inserted into the audio jack.

● If using a Dual AUX 3.5 mm adapter, confirm both plugs are securely connected. Unplug and reconnect it firmly.

2.  Turn off Bluetooth on your phone

● This prevents your earbuds from connecting to the phone instead of the transmitter.

3.  Reset the earbuds' connection

● Put the earbuds in their charging case.

● Close the lid for about 3 seconds.

● Reopen the case and remove the earbuds.

4.  Reset and pair again

● Factory reset the SoundJet R1

● Reset your earbuds.

● Pair them again from the beginning

Why It Sometimes Doesn’t Work

● Loose AUX connection – The plug is not fully seated in the audio port.

● Dual-AUX adapter issues – One of the plugs may not be fully connected.

● Phone Bluetooth interference – The earbuds reconnect to the phone instead of the transmitter.

● Pairing glitches – The transmitter and earbuds lose proper synchronization.

💡 Tip:

When using airplane entertainment systems or older audio devices, the AUX port may feel connected even when it is slightly loose. Push the plug in firmly until you feel a solid click to ensure both audio channels are transmitted.
