- Z55H Battery,Compatible with Sony Headset Battery for WF-1000XM4(2PCS) Truly Wireless Earbud Noise Cancelling Headphones Premium with Installation Tools Kit 3.85V 75mAh

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.

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

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

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!

Viene lo que muestra la imagen y que se requiere para repararlos, en mi caso yo apliqué secadora para facilitar las cosas

las use para los audifonos sony xm4, a funcionado bien

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.

Facil de instalar, incluye todo lo requerido para reemplazar las baterias en los audifonos Sony

No coincide el tamaño de la pila, y casi se rompe mis auriculares.
