### ⭐⭐ Not recommended
*by R***N on 11 July 2025*

The sound quality is poor, plus I received it with no charging cable.

### ⭐⭐⭐⭐ Great purchase
*by P***S on 31 March 2026*

Amazing sound, especially for the price. Case is larger than current earbuds on the market but really I'm splitting hairs

### ⭐⭐⭐⭐⭐ Sound great, long lasting battery (Used 8 hours+)
*by A***R on 18 November 2025*

Gotta have your own headphones! These work wonderful, if your on one device they have no issue connecting. I have issues with multiple devices. As I am switching between three throughout the day. But the sound quality is very clear. The different ear tips make it comfortable as you want.
