As of August 2015, wireless bluetooth microphones are sold online at Nikon and Amazon.com. Nikon's ME-W1 Wireless Microphone records audio up to a distance of 164 feet. It is compatible with Nikon cameras that use a 3.5-millimeter microphone jack.
Amazon.com carries the Sony wireless bluetooth microphone for Handycam camcorders. The product averages four stars on the retailer's five-star rating scale. Sony's microphone has a communication distance of about 100 feet.
Positive reviews say that Sony's range is significantly farther than advertised. In addition, it has a clear sound and long-lasting battery. Less-supportive comments say that the microphone is poorly constructed and picks up excessive background noise.
