## Customer Reviews

### ⭐⭐⭐⭐⭐ Great little bugs.
*by J***N on September 24, 2023*

I purchased this item to use with a reverb box that had an option for microphone input, now I find the little gems are wonderful for listening to rooms during ghost hunts. I supply the local paranormal club with electronic devices for their operation, this has been added used on conjunction with esp8266 devices to transmit the sounds to cell phones of the operators of the investigation branch.
