I bought two of your intercom headsets for race fans. The sound reduction is superior to the comparable Racing Electronic and Racing Radio headsets but the intercom is not. The background noise through the intercom when talking during a race is so loud it makes the headsets useless for communicating or listening to the scanner. The Racing Electronics intercom is far superior (it has noise cancelation). Also, the volume control does not amplify the scanner sound enough and there should be a separate voume control for the scanner and the intercom - like on the Racing Electronics headset. Combining the best features of your unit and the Racing Electronics unit would make an outstanding headset.
