Hello,

thanks for your answer but the warranty is out.

I'm looking for a cheapper solution.

There is a switch in the headphone to avoid charging not rechargable batteries.

I shunted it, but it doesnt work.

I suppose the device is locked and it work only with one kind of batteries.

Which kind, and why?

best regard

Hello,

after a few month of using a headphone Sony MDR-RF4000 I have batteries problemes.

It's written on the headphone that you cannot charge other battery than the supplied batteries.

Does somebody know which kind of batteries will match with this device.

I've allready try with Ni-Mh 850mAh and it does'nt work.

You can buy them, but they are very expensive. It look like the printer market.

Fixe the client.

Bye
