Was not to bad to replace both batteries
Batteries are working great. The flat pic was not strong enough to separate the halves (Sony earbuds) had to use a knife blade after heating with hair dryer.

Perfect fit
Solved the stupid battery issue on these $300.00 ear buds.

I'd probably just get new headphones
If you want to fiddle around and hope it works it could be great. The stupid magnets when you open it makes it hard to put back together

Fixed.
This worked great. I found my left ear bud battery had exploded upon taking them apart... no wonder the L side did not work. Thanks!

Las baterías son las adecuadas y, despues de dos meses de uso, han funcionado muy bien, los he utilizado por 4 horas y aún les queda carga suficiente.
