I have owned the Alpine Moto Safe Earplugs for approx 6 years and they have served me well. The advantage I find over other earplugs is that they have a small hole in the centre to allow for air to flow, this is essential for me as if I wear normal foam ones I get a pressure build up and this causes tremendous pain. I use the plugs approx 6000 miles a year and have lasted me now 6 years, I have just had to buy a new pair as the old ones have come to the end of there lives. They do seem expensive about £20 incl P&P via ebay, but if I don't have problems with my ears I'm happy. The earplug its self is similar to in ear headphones so very comfortable and the centre is a filter, they come supplied with 2 different filters which block out wind noise but allow you to still hear people talking. Pros: Very comfortable Don't allow for pressure build up Last for years Come with a handy carry pouch Cons: None really, expensive but they do last
