Simply put, these are the most amazing little mics I’ve ever used! The Nikon ME-W1 were announced quite a while ago and released last fall and for some stupid reason, they fell off my radar screen. I regret that now that I have them in my possession and I’m using them. The ME-W1 are a Bluetooth (that’s right, Bluetooth) wireless mic system for our DSLR video. They run A LONG time on a single AAA battery, instantly pair with themselves once turned on and plug into the Mic socket on our cameras for very easy use. I’ve done line of site sound recording over 100′ and being in other rooms at over 50′ with them. They are water resistant, Transmitter has its own wind sock (black looking case in photo) and being Bluetooth, aren’t subject to the normal audio interference wireless mics can have. You can use them as seen here or plug a lav mic into the Microphone, both ways providing really amazingly clear sound. And when you see their price compared to other mics … wow, they are inexpensive. If you’re looking for great mics, easy to use and carry at a killer price, the ME-W1 is the ticket!
