Introduction
Most single-celled lithium-ion replacement batteries with the same battery connector should work—as long as they physically fit.
Note: If you’re having battery charging problems, follow this procedure to disassemble your headphones, disconnect the battery for 15 minutes, reconnect it, and see if the problem is fixed before replacing the battery.
To minimize risk of damage, turn on your headphones and allow the battery to fully discharge before starting this procedure. If a charged lithium-ion battery is accidentally punctured, a dangerous and uncontrollable fire may result. If your battery looks puffy or swollen, take extra precautions.
What you need
Step 1
Place the headphones speakers-up
- Before beginning any repairs, press and hold the power button on the left ear cup for about 2 seconds until the blue light turns off.
- Place your headphones onto a work surface, ear pads facing up.

Step 3
Unclip the ear cup
- Insert the flat end of a spudger into the gap you’ve created, between the edge of the cushion and the frame.
- Pivot the spudger down to unclip the long edge of the ear pad.
- When the first clip disconnects, you’ll hear an audible clicking sound.
- This may take a considerable amount of force. If the cushion won’t click out of place, move your spudger to different points along the long edge.

Thanks for this guide. I was able to repair a loose cable on my XM3s with this disassembly information.
Since the design of the models are mostly the same it would be nice to have a similar disassembly guide on the XM3 website too.
