The sound of this player is excellent, it has loud sound, lasts quite a while charged, and is practical to take anywhere.

### ⭐ Don’t waste your time and money on this
*by W***L on December 1, 2025*

This was the worst wireless mic/speaker package I’ve ever tried. The spec sheet says it has 30W of power but the speaker is so light that there is no way it has that much battery or power. The microphone quality is terrible and makes you sound like a (very quiet) robot before delivering very unpleasant feedback. It also feels cheap and plastic-y. Overall a waste of money. I'm returning this immediately.
