This is interesting; a Bluetooth microphone that plugs into the new accessory port of the Flip Ultra. The Scosche freedomMIC. Sure, Blue has announced the Mikey for Flip, and if I had to guess, I would guess that the sound quality of the Mikey is going to be better than the freedomMIC, but when using a camera, often the first, biggest problem to solve is the distance between your source and your mic. Moving the mic up to the source is - generally - going to make more of a difference than getting a better microphone that's further back.
Of course, what you want is a really good mic, close enough.
The freedomMIC features a condenser microphone with DSP noise cancellation and has a range of 100 feet, and powered by lithium ion batteries (in both transmitter and receiver) that gives 4 hours of operation. Users can wirelessly control record and stop functions remotely from the microphone/transmitter. The receiver features a pass-through tripod mount for securing the receiver to the camera and retaining the ability to use a tripod.
The big question; how does it sound? We'll have to wait and see.
The freedomMIC will be available at scosche.com and from retailers that sell the new Flip cameras that feature the new FlipPort line in mid to late December 2010 for $99.99 MSRP.
