Just wanted to chip in here - I've been playing with a few solutions. Have a look at some Sennheiser kit - I use an AVX receiver on my hoodie - hooked into my iPhone via the lightning adapter and the Rode plug to make it work. you can also look at the rode lighting to xlr cable - iXLR which also has headphone monitoring. Sennheiser have a 'clip mic digital' which works great and is good for blogging. If you want to record something different have a look at their ambeo smart headset - binaural recording very cool. Obviously you have wires which can affect the motor movement etc. but if you keep them thin and away from the motors you should be good to go.
