As well as visor cleaners, we're passionate about hearing.
Paul, the boss here, has irreparable hearing damage from riding noisy bikes without earplugs in his youth. (He even got a hearing aid aged 34 - mind you, he doesn't wear it!)
So, if you're not protecting your hearing already, you might want to consider starting now!
These Moldex earplugs are really comfortable and they have an excellent noise attenuation level of 35dB, which mitigates just about all the potential risk of hearing loss from riding motorcycles.
