Introdução

    • Try to ensure all batteries are drained to below 15%. This reduces the risk of nasty surprises if the batteries are damaged during removal.

    • Gently press a razor blade into the seam around the bulb on the ear bud.

    • Take care to follow the seam because the razor can easily go off track and cut a little slice of plastic from around the seam.

    • Allow the razor to cut no more than 1mm into the seam around the whole bulb.

    • If necessary, run the razor a little deeper around the whole seam until the cap can be pulled off.

    • The battery cell inside is held in with red glue.

    • A little heat helps soften the glue. Use a heat gun or hair dryer.

    • The glue can be gouged out with a screwdriver until the battery can be convinced to pull out.

    • Take care not to short-circuit the battery.

    The battery is actually held in a small clear plastic ring, with red glue.

    It's easier to pull out the ring (holding the battery), and then remove the battery from that ring

    • The new battery can simply be pushed into position.

    • Use B7000 or any similar rubbery glue that has a needle applicator - apply around the seam and close the earbud.

    • Wrap a rubber band around the bud until the glue has fully cured.

    • Repeat for the second earbud.

    Thanks for simple but useful guide, for remove batteries i use the solder iron at 250 to directly heat the batteries and loose the red glue...

    However i don't find guidelines for replace the base battery... But at the end i figured out myself...

    Start to open the internal lid assembly with persuasion, then remove the metal hinges spring and with a little of persuasion the base cover come off...

    There isn't glue, but only a clever mechanism that use the hinges metal part for secure the base cover...

    Thanks! The base battery replacement guide is here:

    I think it may previously have been marked as "In Progress", so maybe not listed with this one. Sorry about that.

    I'd recommend being very careful using a soldering iron on Li-Ion batteries! Especially old ones 😬

my one started distorting lhs. I had to open it to fix the membrane in place. Not quite the same as this tutorial but it helped me to find how to open it.

Hermes Almeida -

Can you please share how did you fix the distortion?
