No experience w/ the unit discussed, but I did purchase a couple of the acoustic tube earpiece sets from ebay with a remote, lapel mount for the mic.? See ebay item # 160507398573.
Very inexpensive but I've used it for several ARES supported events.?
FWIW, my net control folks said they couldn't tell the difference between it and the Yaesu speaker mic.
