Nikon ME-W1 Wireless Microphone Set Review

Not actually waterproof, but somewhat water resistant. The rating is IPX5.

This makes it possible to use a higher quality lavalier microphone or even a stereo microphone such as the suggested separate purchase of the ME-1 microphone from the same brand Nikon.

You can record just the audio from the transmitter or you can record audio from both transmitter and reciever units eg the guest and the interviewer.
