Item was as described, fit great, pricing & shipping cost were fair. Delv time estimate at time of purchase was not accurate and delv took 2 weeks all together. Given that the item had to be handled by USPS as Hazmat shipment in early Dec we feel that a 2 week estimate of a possible time would have been better. Other than the unexpected shipping time, the item, communication & transaction were all great & we will purchase again from this seller. Thank you

    Great replacement battery

    I was pleased to find this battery because it was so inexpensive, maybe $10, I can't remember. What I do remember is the Sony battery it replaced in my headphones was priced at $100. Ouch! So when the replacement was delivered, I was almost afraid to try it out. But when I set it in Dad's headphones it took a charge, and my dad says the phones haven't run down before he wanted since. This is a great little battery and a bargain too.

  • Excellent battery & price

    That batteries for a set of Sony earphones that I bought over 10 years ago. They never worked and now I know it was because the battery was just no good. This new battery has put life into an old set of headphones. Thank you very much!

  • Great battery, works really well!

    Great battery, works really well! I am hearing-impaired, so I must use wireless headphones to be able to watch TV, and with this new battery I can do that for many hours at a time!

  • They work fine as a replacement battery for my Sony wireless headphones

    it's a good replacement for my Sony TMR-RF970R headphone batteries. Fits perfect and holds the charge a long time- 5 hours or more. Holds the charge longer and last longer than the original Sony batteries.
