I love the panel powered plugs. Less wires, no batteries. It's just great.
The other day I had an instructor fly with me and he wanted to use his own dual plug headset. Oops, got no plugs for that. It's probably a good idea to have the other style plugs also or at least an adapter cable.
Lightspeed's control boxes are becoming larger and larger... and now with the wireless option one more battery to worry about. They looked at me funny when I asked them if I'd have to include their box in my W&B calculations.
You may be looking for ANR, but you can also get a Halo with dual plugs for now and then when your 10 is done have it converted to a lemo style plug. They are great and cost way less than a Bose A20 or AKG.
