## Customer Reviews

### ⭐⭐⭐⭐⭐ Headphones
*by S***D on December 22, 2025*

Work very well and the voice quality is very clear when giving a tour

### ⭐⭐⭐⭐⭐ Works great!
*by K***N on December 29, 2025*

I’m a guide in a sprinter van with 14 guests. This works great! Simple, travels well! Just charge it each night to assure I don’t run out of power!

### ⭐⭐⭐⭐ Good for the money
*by J***R on April 28, 2021*

Excellent product for the money. After taking it apart I found it uses a very long antenna that travels the length of the wire support. This improves the distance it will transmit. The wire support is very stiff. This could make it difficult to bend for fitting larger or smaller heads.
