It works well as a replacement rechargeable battery for our vintage Sony wireless headphone system. We have two headsets and replaced the original Sony battery with one of these two or three years ago. It is still holding its charge very well and we're pleased to see similar results with the latest installation.

It took longer than expected to receive it, but they work good in my Sony headphones.

These batteries fit my Sony TV headset perfectly. This is the second replacement set that I purchased. The first set lasted about a year…a bit less life than I expected.

I've been using this battery for about a week and is doing pretty good. I charged for 24 hours the first time despite showing some juice. I do recommend this product.

I bought this two months ago for a replacement for my Sony wireless headphones. They fit fine in the headphones. The batteries initially charged fully but after a month they never fully charged even after sitting in the charger for 16 hrs.

I ordered this as a replacement for the battery inside a set of wireless headphones. I didn't realise when I ordered it though that it was coming all the way from America as it didn't state this clearly on the page when I ordered it. A bit crazy to order something so small to come such a long way when I could have got it from somewhere here in the UK. However, it arrived and is doing the job it was intended for so that's all that matters.

I was wondering if I was going to have to retire my favorite Sony remove headset that I use for TV/computer use. This great battery saved the day. I was down to 2-3 hours of listening on a charge with my old battery... I can go many, many hours with this new battery of yours, and the signal strenght is so strong that I can here my TV broadcast way out to the patio area where I live (at last 140ft away).The battery arrived very quickly and in great shape.So, great product and much thanks for making it available at amazon.com!Bonnie
