### ⭐⭐⭐ Review
*by O***R on 26 September 2025*

I've had these for 3weeks now and they are very loud pair of ear buds and nice feel and touch to the earbuds and case. Bluetooth Connection is fast enough and battery life is pretty decent. However there is slight bass distortion when U turn it up beyond 75% but good treble and mid sound quality. For this price I can't complain too much. 🤓
