Batteries are defective and non-returnable

I just pasted a RoberE review. My experience is exactly the same, only the Sony earbuds are different. My only regret is that I didn't read this review and saved myself $10. I received this product yesterday for use with Sony MDR-RF925R headphones. None of the cartridges work, my Sony base unit doesn't recognize them at all. I wanted to return an item and found that this seller does not accept returns. I'm guessing that means Revain justifies the practice of sellers selling junk to their AMAZON

Pros
  • Meets or exceeds OEM products. Manufacturer's lifetime warranty
Cons
  • Expensive

it works - after a few months they lose their charge faster

They work great with my Sony headphones. It didn't look exactly like the photo but they had the same part number and specs and still worked fine. - see photo.

I used my regular battery and it lasted twice as long at around four hours. These batteries should last about 7 hours. Maybe I got a bad…

Didn't work in my Sony headphones at first.

I put them in my Sony headphones and was disappointed that they still wouldn't charge. I was very surprised as I thought I had confirmed for sure that my original batteries were defective! After spending a little time I realized that there was a flaw in the design. The tops of the cells are too thick/wide/flat to hook the contacts on the headphones; and that was the reason. I ended up just taking the items out of the "packaging" and found that they weren't charged YET. I then discovered that…

Pros
  • Capacity: 700mah 2.4V NiMH batteries
Cons
  • Hard to say
