How to Fix Beats Solo 3 Wireless Audio Not Working On One Side


Beats Solo 3 Wireless Headphones on Amazon

Here is how I fixed the Beats Solo 3 Wireless headphones to fix the problem with audio not working on one side when connected with bluetooth. In my particular case the right ear cup (the one with the micro-USB connector) was not producing any sound.

To fix the problem I did the following:

1. Open up the left ear cup carefully
2. Take pictures of where each cable is connected to and make notes
3. Removed the headphone jack and circuit board
4. Cut all the wires from the circuit board
5. Connect all the negative, ground, and DET wires all together by soldering them together
6. Connect the Bluetooth Left and Right positive wires to the corresponding positive leads of the left and right headphone speakers by soldering them together
7. Carefully put the left ear cup back the way it was
