I want to replace the pads that go between the headset and my head. Can these be purchased? Also, is there perhaps a foam cover that goes over the existing pad.
Thanks,
Thom

I notice this mic is suggested for drummers who I assume get sweaty. So, is this mic suitable for group fitness where we get very sweaty, is it sealed to be sweat resistant?

Thank you for you inquiry. Yes, it can be used for a fitness group, although i recommend the Pro 8he instead. It is a very similar mic and costs much less.Age:Â 45-54
