I personally don't like being paired with someone using the uflymic. They spend most of the trip trying to hold the mic in front of their mouth because for some reason it just won't stay close enough. The A20 works great. I've never been a head clamp guy so it is not for me. I've used the Telex 5x5 for years with a homemade earplug earpiece, but I've recently been shopping for a better solution for both ears as we use the intercom now in the 737. I have to have a TSO headset per our FOM and the sticker shock on the CA was scaring me. I finally got some plastic tubing that is an air line for RC airplanes and a t connector. I use three tubes, one from the 5x5 for sound to the T, then one from the T to each ear terminating in a regular orange Howard leight earplug. I melt holes in the earplugs using a torch to heat a small drill bit, then plunge the hot bit into the ear plugs, but not all the way through. Fantastic sound quality and you can't tell you are wearing a headset. During the day I clip the mic to sunglasses, but at night right now I have to use the frame the 5x5 comes with until I find a better solution. I'm thinking of clipping it to my earlobe somehow.
