Earplugs + Cardo : Trying to make it work.

I'm trying to solve my audio issue at the moment. My Shoei is fairly lightweight meaning that there isnt much sound deadening. I currently use a Cardo Packtalk comms system for audio and wear rubber christmas tree style earplugs. The challenge is that at speeds above 50 it get's difficult to hear music and GPS guidance regardless of whether or not I have protection in. So the question is what solutions do you guys know of that can help me isolate headset sound while still cutting down on wind noise? My tinitis and I thank you in advance!
