We just made the original better! Now with coiled cord! Racing earbuds. Low cost and we just made them better. Works with most scanners,-all racing helmet kits 3.5 Wired mono. We took the standard Challenger Mono Earbuds that we have sold 1000's of and shortened the cord and added a coiled cord section. The original has always been a great low cost options for scanners, racers and helmet kits but sometimes in a cramped racecar the extra long cord could create problems. Problem solved and no more extra long cord flying around and getting tangled up in suits, belts etc. 3.5 standard plug. Wired mono for racing apps.
