Wasn’t sure if this the right page section to post. I currently own a peltor comtac 3 single com. I want to add one more so I can throw the 3 on my helmet but can’t find an answer. I know the 5 and 6 is an upgrade to the sound quality over the 3 but between the 5 and 6 is the sound quality any different? I know the 6 has extra profiles and the NIB but in terms of sound quality are they different or better? None of my guys uses the 6 so the NIB would be useless for me but if the sound quality is worth the extra money I’d like to know.
