Hi guys I just bought an HJC I71 helmet and because its a bit tighter fit then my previous helmet, I wont be able to use my IsoTune earphones anymore. I looked into getting a comm system for this purpose and a guy at my local shop recommended Cardo. Im split between Freecom 2x or going down the integrated route with HJC 21b. Can you recommend any of these or advise against? Thanks
