Me quedo excelente en mis buds de samsung

Got these to replace the batteries in my Sony XM3 earbuds. Installing them was easy. Many YouTubers show you how. Price point was ok. Update: As with the OEM batteries one side drains faster. After one hour one side is down to 70% and the other is down to 50% which is not great it seems to me. I assume they might well give me 2.5 hours of run time if I ran them till they shut down.

I bought these batteries to fix my old dying headphones and one of the batteries works well so far, charging and holding a discharge during use, while the other replacement battery started out that way and quickly became bad. By bad I mean that it says it’s 100% but then quickly dies after 50-60 minutes of use. When the bad side dies the other battery is at 75%. Roll the dice with these if your lucky. I’m at 50/50 with good/bad cells.

So far working great. My Samsung Buds had battery issues and would go from 100% to 0% in a few minutes. Installed these replacements and they are like new again.

The batteries are well priced compared to all other brands found online. The shipping was fast and the installation was not too difficult. The battery life has been around the same as the oem batteries. I'm hoping they last for at least a couple of years.

Works, however, only ended up holding a charge for just under 2 years (purchased late 2023)

Correct size. Both earbuds worked for about 4 months. Then one stopped working. When the second stopped working I opened them back up after charging for 24 hours and the batteries read approximately 3 volts.

Proper fit in my Sony MX3 earbuds. Nonstop music once more for hours on end.
