## Customer Reviews

### ⭐⭐⭐⭐⭐ These are excellent.
*by S***Y on February 8, 2020*

Not only can they be used as sound level meter sensors used in many projects, they are actual microphones that can be hooked directly to a pre-amp, mixer, or an analog to digital converter. If you use 5 volt power, output levels, even from background noise, will be almost 5 volts, and any intended input will clip. Using 3.3 volts on Arduino or Pi will give you about a 2 volt floor that will eliminate most clipping. There is some slight noise in the output, so I am going to try 2.5 volt vcc. Great find.

### ⭐⭐⭐⭐ Works pretty well, but seems to eat batteries.
*by H***R on May 20, 2025*

I rigged the microphone up with an old amplifier and some earphones to facilitate conversation with my hearing impaired wife. The setup works really well, except that I powered the mike with a couple of AA batteries. Sadly the batteries don't last very long. I haven't measured the current drain yet, but it must be fairly hi,

### ⭐⭐⭐⭐⭐ Item received as expected.
*by E***Y on October 20, 2023*

Prompt service. I ordered these for a students project. Unfortunately I threw the package away and had to reorder. Second order arrived quickly. No issues with devices. Student has will install next week.
