Been using the Griffin iMic as part of my iPad remote setup. Works well. Also use it with my MacBook Pro.
Bought a new laptop that has a combo mic/headphone 4 pin 3.5 mm TRRS jack. Bought a combo splitter cable for $10 at MicroCenter which gives me the pink and green 3.5 mm TRS jacks that the Heil headset plugs into. Just a little easier that the Griffin iMic due to size.
