Now this is a great find. The DSLR Film Noob himself gives us a couple of videos demonstrating the results of plugging microphones into a low-cost (eBay, $35) bluetooth transmitter and receiver. In the first video he uses standard mics with good success. In the second he uses the same cheap Radio Shack lav mic that I use with mixed results (dangit!). I think it's pretty cool that Deejay came up with and tested this idea, as we can all benefit if we need a wireless setup with microphones we already own and use.
Be sure to read the accompanying blog posts as well. They will give you more details and links about the hardware Deejay is using in his demonstration. The first is "$35 wireless bluetooth setup, and it works great!" followed by "Bluetooth setup with a lavalier".
UPDATE: "More Bluetooth Wireless Audio Testing"
