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

Works flawlessly! I adapted it on a portable emulator console and it does the job.

Installed in a pair of Sony WH-1000XM3s with no issues. Holds it's charge and works perfectly

My child found a cosmo that was sitting in the back of the closet from 7 years ago. Older sibling lost interest and was never a techie. Batter had died. This was used to replace the dead battery. Had to disassemble the cosmo and reassemble. Handy dandy was able to figure it out. My 11yr old is now harassing me for an emo pet thats about $400. This kid. Seriously. Wants only techie stuff thats more appropriate for an adult (3D printers, apple vision pro, oculus, and now the emo).I digress. Cosmo works perfectly now. But my kid now wants an upgrade. Sigh.

Quedo perfecto a mis cascos Corsar. Fácil remplazo.

Works amazing in my Corsair Void RGB Pros! My headset just wouldn't turn on and would not charge so I searched and found out that the battery might be the problem. So I ordered this battery replacement.I watch a video on how to disassemble and replace the battery which was super easy. I was even to expecting to splice the wires but I didn't have to. It even came 60% charged!Great replacement!
