The IMC Motorcom HS H140 7 Pin half helmet headset is designed for the factory installed intercom system on Harley Davidson models equipped with a 7 Pin audio/intercom system. The headset allows riders with a half helmet or no helmet to utilize all of the audio system functions flawlessly. Now you don't have to let your headset make you use a certain type of helmet. This combo provides better performance than headsets that cost twice as much and have half the warranty. The rugged coiled connecting cord is designed for years of reliable service. The over the ear speakers offer excellent sound quality and do not require a helmet to install. The special noise cancelling microphone will make this a must-have for your next trip.
