Q: What is the difference between ear seal part #'s 11-09262 and 11-01782?
David Clark has two types of earseals, foam and gel. Gel will be more comfortable and can be found under P/N 11-01782. However, if you live in a warmer climate you will also want the cloth covers found under P/N 11-04793 to avoid slipping due to sweat.
Q: Are the part # 11-04820 gel ear seals David Clark Brand? or are they manufactured by another company?
