Terraphone Clubman open face headset. A universal intercom headset for use with open face helmets, which includes to earphone pieces with stitch in or stick in Velcro attachments and an adjustable standard microphone boom, perfect for use with the Terraphone Clubman or Terraphone Professional amplifiers from Terratrip. Fully wired with self-adhesive microphone boom mounting, to fit on the outside of your helmet.
If using an open face helmet in an open top/open cockpit car, use these Terraphone Clubman headsets and not the Terraphone Professional headsets, irrespective of the amplifier being used. This is because the Professional headsets feature noise cancelling microphones, which due to their back to back microphones, will try to turn off the whole time due to wind noise in the face, stopping or interfering with communications.
