iMC has made some improvements to the main headset kits for its Harley Davidson, Honda Goldwing and BMW and 6 Pin CB heasets. The interface between the upper and lower headsets is now a circular mini-DIN connector which improves moisture resistance and increases durability. The new headsets have a P appended to the name (example: HS-H140 becomes HS-H140P)
Also worth noting is the helmet headsets now include acoustic pads on the speakers to improve sound quality at higher speeds. These comfortable foam pads will keep you rocking and talking all day. (see image to the left). Additional improvements include support joint for the upper headset wiring on helmet headsets and improved microphone performance.
