Norm Posted May 18, 2006 Report Share Posted May 18, 2006 Hey everyone, I finished putting in my new zetaliner from Oregon aero. It has improved the helmet comfort 100% but my earcups are a little tight. I am wondering if you can buy diffrent thickness earcups for the sph-4 helmet. I tried my david clark gels but they are to small. Thanks Dan Quote Link to comment Share on other sites More sharing options...
