I've been using a CC26 4 pin for the past 15 years or so. Should upgrade to the leatherette earcup.
I have ventured into the wireless
headset realm. I have a JK Audio
Blueset on my com pack and have gone with a bone conduction
headset Shokz Opencomm. I find it works really well, keeps my ears open if I need to hear the mix or if someone comes and talks to me or if I need to jump on the fly
rail quick (tangle-free). I use it both on a wired CC pack and a wireless
Telex BTR300 pack, so then I'm truly wireless. Although that
system is aging rapidly... hoping to put in for a free speak
system upgrade soon.
