📝 Sennheiser 250BT Battery Replacement

Cracking open my Sennheiser HD 250BT headphones. So far the only Bluetooth headphones I can stand so would quite like to keep them running my past the inevitable battery death.

They also look a lot like my favorite work headphones the HD25s and that just makes me happy 😆

The battery is in the right ear cup (the one with the buttons), just take off the ear pads and unscrew the four screws, then gently pull it out, there are some thin wires to be carefull with here.

Annoyingly looks like it will require some soldering to replace. On the plus side it’s only lightly glued in place. The serial number seems to be AHB402035PLT so I’m on the look out for a replacement! If anyone spots one let me know.

Will update this post if I find a replacement and successfully replace it.
