Does anyone know of any dual input headphones, with individual volume on each ear. The reason I ask is I am a big airshow fan and typically like to have at least two scanners on me, one for airboss and one for show discreet, or in the case of jet teams, one for the damond and one for the solos. The way I do this now is just hook them into a splitter, but it can be hard to listen like that at times. I got this idea from wacthing NASCAR, where they have one headset with two radios attached, and they can talk to either individually, at least I think thats how that works. Any suggestions would be a big help, and if this is posted in the wrong place, mods feel free to move it.
