I got a pair of them made several years ago,they were ok, but not near as effective as the foam ones, plus with the moulded ones you are supposed to renew them every 3 years as the insides of your ears change shape apparently.. I also tried the Pinlock, they are better than wearing no ear plugs.. ,again not nearly as good as the old fashioned foam ones, I threw my pinlocks in the bin..funnily enough I couldn't give them away even although I had only worn them once and there was very little ear wax on them!
Might be two pairs, but two different sizes and only one set of filters, so not really two pairs, this is the standard pack.
I got given the Senner MotoPro for my birthday. Look very similar to the Pinlock ones and work well for me. Odd how the Senner ones don't seem to be stocked by bike shops though.
