Good luck. I called Peltor direct about their Tac6S muffs because trying to remove the pads to change the batteries is so difficult due to the cheap unfinished plastic that it causes the potential for breakage. One of the exterior shells cracked and both ear pads/cushion whatever they are cracked and broke. They said send in the shell to get fixed on my dime since it was obvious abuse that caused the breakage, and that I could buy their "hygiene kit" that includes the ear pads from midway for $19.99+ shipping. Thanks for the help, couldn't be your shit design and cheap foreign made parts that make changing batteries so difficult that things can break. My Howard Leighs don't have an issue with battery changes. I've had better customer service from disgruntled teenagers at McDonalds. Peltor/3M, FU.
