The best bang for the buck are the MSA Sordin 75305 headsets available on auction sites. New they run about $140-$150 right now. They use a 6-pin LIMO connector which is incompatible with most push-to-talk units with TP120 receptacles. However, if you are only using them for ear pro, that not an issue. They give you all of the features and performance of the Supreme Pro X but at about 65-70% of the cost. Just tuck the mic and downlead out of the way and you're GTG.
