I purchased two new rechargeable batteries for my Sony MDR-RF960R wireless headphones. According to the specs this battery was supposed to be the replacement battery to use. When I received them my first problem started with the battery holder at each end of the battery was slightly larger than my OEM batteries. In order to get them to correctly charge I had to force them into the slot so the positive end would make the connection. The second problem started when I went to remove the new batteries from the headphones the holders on both of the batteries came off. Now when I put the batteries back into the headphones I have to slip the holders on and then make sure they're lined up properly before I force the battery back into the slot. The third problem comes when the charge for my new batteries only last about an hour before I start loosing connection. The original batteries typically lasted between 2-3 hours. This is not my idea of a quality product.

I installed this as a replacement for a battery that was shipped with a wireless headphone. The original battery lasted for several years. This new battery also works fine and added a few more years of useful life to the wireless headphones.

Battery for Sony MDR-DS3000, MDR-IF240RK, MDR-IF3000, MDR-IF540RK, MDR... product was just what I needed, easy to instal, great package. Went into the headset easy and without any issues.

With these batteries my headphones work again . There no problems with recharging or fitting into the headphones as others may had said .

It was exactly as advertised. We replaced old battery and everything worked great. We would recommend it as replacement battery.

Great product. my son is so happy to have his wireless head phones working again. Happy family Happy life. fred

The batteries were dead and unchargeable. I elected to not return the batteries. "Bit once, not twice." I will order another SONY head set later.

Have not had to use it yet. Wanted it for backup as present battery is several years old. This one matches perfectly and should do the job.

I purchased 2 batteries which fitted my Sony MDR-RF800R headphones without any problems. Can't comment on lifespan but both were less than the price of 1 Sony replacement. No complaints

We've bought this as a replacement for my son's headphones and it arrived the next day and the price was more than allright for me.My son is happy now so job done

Great battery great price.

As good as original but a lot cheaper.

Excellent product, good price and quick delivery!
