## Customer Reviews

### ⭐ Battery doesnt actually work
*by A***Y on January 19, 2025*

Installed easily, but case double-blinks the red indicator light. Battery will not charge.

### ⭐⭐⭐⭐⭐ Works great!
*by T***N on August 16, 2024*

I had to replace the batteries of my XM4 buds due to the Sony update bug that bricked then and decided to change the battery in the case as well just to have a full fresh start. Unlike the buds changing the case battery wasn't hard at all with a youtube video, patience, and concentration making sure to avoid not rushing and messing up any wires. It's been maybe a month since I swapped the battery and the battery life on my case and buds have been great.

### ⭐ Doesn't seem to work with WF1000XM4
*by B***T on November 18, 2024*

Case just blinks red and does not charge when this battery is installed.
