    • Start by inserting the iFixit plastic opening tool into the crease between the hard plastic and the ear cup on the right side of the headphones. Then you should gently apply pressure until it separates.

    • You may need to repeat the process on the back using your hands or the iFixit plastic opening tool until it separates completely.

    • This may take a considerable amount of pressure but do not force it.

Hi Braden!

Thanks for this manual looks easy. What is the best shop to buy a spare battery? Can you use the Sony SP 624038 ? It has slightly different specs (3.7 v instead 3.6v and 1000 mha instead of 925 mha). Would be an interesting upgrade.

Regards,

Marvin

Since I could not find an SP70A battery, I ended up replacing the battery with an authentic SP70 battery that was rated at the same 925mAh and 3.6V.

Not easy! He doesn't mention that all the wires and battery plug are bundled and wrapped with thick sticky black tape. I tried cutting it with small surgical scissors and since it is blind cutting, cut a couple of wires. Headphones are ruined now.

Thanks to you I have replaced the battery but seems like the new battery isn't holding the power as well - originally a water damage but the charging works and the headphone worked with aux and the old and new battery holds power somewhere between 4-6 hours. Is there a ground pin or something else that is leaking the charge?
