I typically use the yellow foam earplugs you get from bunnings but I am sick of how they feel. Every time I get some wind buffeting my helmet they get pushed into my ears back and forth because they project out of my ears slightly and contact the inside of my helmet, even after I have cut them down a little. Anyway, I am looking for alternatives... Has anyone used a pair of these : http://www.diycustomearplugs.com.au/diy-custom-ear-plugs-ear-plug-motorbike-kit-p-10.html?zenid=eba66b39ea26593dd5380aff5d5d4df6 I would love a set but the price is a bit steep at $45. Or does anyone have a cheaper DIY solution (blue tack doesnt count). I guess if they are fantastic I could sc**** the cash together.
