Advertised on ebay, and have my doubts. Shows a microphone and speaker
A microphone that small has to be an electret, hasn't it ?
How is that supposed to work wet ? Or is it another marketing plot ? What is your opinion ? Could it ever work ? Is there any electret in the market that can work submerged ?
