TIPS

1. I found a utility knife blade without heat was the best way to open the cases.

2. Didn't remove the ZIF cable, there was plenty of working room

3. Broke the tip off my spludger which actually made it better for removing the batteries

4. Only lift the connectors a tiny amount if they are flat, too much and they'll break.

5. Reinitialized the earbuds when you're done.

Hope these tips help.

The contact only needs to move 1mm at the most. When you reassemble the case presses the circuit boards and batteries in place.

I was cautious and didn't bend mine too much and they were fine once reassembled.

My spludger tip also broke, but it actually made it easier for removing the other battery. 😄

I too skipped removing the cable and managed to get the batteries out without trouble.

I initially tried the hair dryer and a stainless steel pryer but wasn't getting anywhere, the only thing I managed was to scratch the casing.

I switched to a utility knife blade and opened it in about 20 seconds.

The second pair I didn't heat and that one opened even quicker.

I don't think there's that much glue to require heating.
