Solid replacement part for WH-1000XM4s
Seems to be a good quality replacement for the original: battery life on headphones lasts much longer as a result.

Revived my WH1000-XM4 headphones
I was suffering with bad battery life, the new one lasts for ages and was pretty easy to install, charging and everything seems to work without issue, and no need for any calibration steps, make sure you remount the temperature sensor properly though!

Fitted without problems.
Sony v3 headphones - Fitted without a problem. Slightly bigger dimensions of the battery (accounting for increased capacity over the standard), prove no problem.

Useless Battery. Avoid.
Doesn't hold charge! Ran down from full charge to 10% next day even when not used. Happened Every time.

Doesn’t charge up, doesn’t charge headphones
The battery doesn’t power my headphones after being charged for hours. Very disappointing and will be returning.

Una batería pequeña apta para los robots de Anki Cozmo y Vector. En mi caso fue para un Cozmo al que la batería que venía de fábrica no aguantaba ya la carga y era necesario reemplazarla. La batería viene con un conector JST típico en baterías y un pequeño trozo de tubo termorretráctil (que no utilicé). Buena calidad y mayor capacidad que la batería que venía de fábrica con Cozmo. Eso sí, si os aventuráis a desmontar a Cozmo, tened en cuenta que, aunque es relativamente sencillo, hay que hacerlo con cuidado, y la batería tiene que ser soldada a la placa. En cualquier caso, la batería de momento cumple bastante bien y aún no he tenido que cargarla desde que se la coloqué al robot.

Der Akku hat unser Babyphone gerettet. Der Originalakku war aufgebläht. Dieser hat zwar marginal weniger Kapazität, passt aber ins Gehäuse. Lädt und halt die Ladung...
