So on saturday while I was at the motoGP I saw earmold australia had a stand in the expo. They were doing sets of ear plugs on site @ 70 bucks for a completely standard pair. Decided to get a set as the weekend before I did 800+ Ks of riding with a disposable pair that I couldn't get to consisently work with my left ear, and kneading them got annoying. (They still make a huge difference and I encourage everyone to use them at least) Molding only took about 15 minutes, ears are washed, a cotton plug is inserted in front of the drum and they inject the silicone mix into your ear (tickles!). You get to sit there looking like you've got an infection for 10 minutes or so while it sets. Conclusion after picking them up for the ride home: Money well spent. They reduce the roar from around 90+ to a whisper (which is actually quite pleasant, as sounds are still important). No problems hearing people and they're pretty comfy in the helmet also easy to insert, but removing them is a little tricky at first.
