## Customer Reviews

### ⭐⭐⭐⭐⭐ Audio
*by M***N on 8 November 2025*

Works great thanks

### ⭐⭐⭐⭐⭐ Great Audio mixer
*by S***N on 30 December 2025*

Great little audio mixer. Able to control audio from PC and Mini disc player into audio setup.

### ⭐⭐⭐⭐ Does exactly what it says, but attenuation is very high
*by J***E on 22 May 2024*

Works exactly as described. I used this to combine a drum trigger module with my iPhone and it works perfectly well. However, the attenuation of the signal is very, very high and therefore too quiet to use with earphones or headphones. Rather than spend additional money an a headphone amp, I decided to return this and buy a battery powered mixer which does exactly the same thing, albeit for twice the price; but still significantly cheaper than buying a headphone amp in addition to this.
