## Customer Reviews

### ⭐⭐⭐⭐⭐ Lo recomiendo

Practicos

### ⭐ Case just stopped working
*by R***A on November 6, 2024*

I'm about to reach out to support now, but my case decided to stop working. It had charge, wasn't dirtier, and the earbuds were not sweaty.Was really hoping this would work, but it looks like it won't. :/Edit: Waiting for a second pair to be sent. I really like some details, so I am hoping I just had a faulty piece, versus a faulty product line.

### ⭐⭐⭐⭐⭐ Good sound
*by E***N on February 5, 2025*

Functions well. We ordered black but received white. Not a big enough deal to go thru hassle to exchange.
