This PRO-POD system is an alternative helmet sound option to the normal helmet kit or earplugs.
The Rugged Radios PRO-POD is a gel-cushioned headset with Alpha Audio speakers that can be used with any 3.5mm mono input jack for in-helmet audio. If you have struggled to hear your pit crew with your previous system then these will certainly improve communications by greatly increasing noise reduction.
The Pro-Pod is very popular with Impact helmets, but it may not fit all other helmets without some level of modification.
