This is one of those gadgets I've been waiting for.
Small, discreet, and it connects to your iPhone or iPad over an established wireless protocol instead of some proprietary solution. The FreedomMIC looks like it could be the right solution for podcasters and vloggers trying to minimize the amount of gear they have to haul around.
Standard bluetooth range of about 30ft, and it records to a Scosche designed app available in the App Store. I wasn't able to try it out (since I was rocking Android and WP7), but I'll be curious to get my hands on one to see how it performs.
Babysteps, but products like this are a step in the right direction.
If you buy the Scosche FreedomMIC off of Amazon, you'll be supporting SomeAudioGuy!
