I've been looking for a solution to the problem of being able to listen to music while riding, without killing my hearing for ages. I always wear ear plugs while riding because I value my hearing. I already have tinnitus, and I don't want to make it worse, and there is no doubt that the wind noise while riding WILL damage your hearing. I started with disposable foam plugs, then got custom made earmolds done. The foam plugs are more effective in my view, but others seem to get better results. But I like music, and on long highway rides a little music would assist the ride. I didn't want to pay the exorbitant amount for the earmold option - air tubes inserted in custom moulds, which could result in problems of noise generated from wind hitting the air tubes. Not at that cost. I bought some DIY moulds that go over supplied in-ear phones from the US, but they were really quite awful. The sound quality was terrible, and the noise suppresion was useless. Perhaps I did it wrong. Anyway, they were cheap, and for me a failed experiment. I tried other in-ear phones without getting sufficient noise suppresion. I heard about the Etymotic noise isolating earphones, which have a db noise reduction rating, and everyone said the ER6i were the ones to get due to their low profile - fitting under helmets. But! No longer available, and the replacement didn't look terribly helmet friendly, or particularly cheap as an experiment that may fail. Recently I found the Ultimate Ears from Logitech. These actually have a db rating for noise reduction, which I thought was a good start. The UE200 versions were low profile and looked perfect for under a helmet. They were also pretty cheap, and they could be bought at the local Dick Smiths store. I decided I could take the chance and see how it went. I went and bought them, and got them for just over $20 as Dick Smiths had them on 40% off! Back to try them in the ears. Hmmm. First impressions were not so good. Despite the wide variety of silicone rubber fittings I didn't find them overly comfortable, and the noise reduction wasn't incredible - not good enought to trust my hearing to them on the bike. Bummer. The final option was to add an extra to them - Comply foam tips. I have heard various people get very good results from these. They replace the silicone rubber ends on the ear phones. I bought them on ebay from a seller in Singapore for not a lot (under $20 for three pairs), but you do need to make sure you choose the right type for your earphones. Fitting them to the earphones is very simple. I then use the 'lube ear with saliva' method, squeeze down the foam, lift my ear like I would if inserting a foam ear plug and put the ear phone in, holding it for a moment while the foam expands in my ear canal. The fit is then excellent, and the noise isolation is superb - at least as good as my custom earmolds! Around town I put my music on before staring my bike, set the volume at a comfortable, normal, non-riding level, start the bike and ride. The volume is still fine on the bike! Like riding with foam earplugs I can still hear the bike, other vehicles, emergency vehicles etc, but the surrounding noise is greatly reduced. The music is perfect. I highly recommend Logitech Ultimate Ears UE200 when combined with Comply foam tips if you like music when riding but still want to protect your hearing, and want it all at a decent price. For me it was all up around $40, which I reckon is pretty good. Certainly beats $300 or so for Earmolds with air tubes. Hope this is helpful! Cheers!
