Terraphone Clubman and Professional V2 practice headsets from Terratrip, now with a revolving microphone boom for use either side of the vehicle. As used by rally drivers around the world and are used for clear communications during road sections in between rally stages. Most countries, don't permit the wearing of a rally helmet on road sections, so in noisy rally cars, clear communications between driver and co-driver are still vital and the tedious drone of engine and transmission noise induces tiredness and stress, making communications in the car strenuous to say the least. These professional headsets keep out the noise and ensure calm communications can resume. These new headsets are compatible for use with all Terraphone Professional and Clubman amplifier models and feature comfortable full earcup earphones, an adjustable noise cancelling microphone boom and a comfortable, adjustable headband.
