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.

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.
