I was a bit sceptical
I was a bit sceptical about spending this much for some ear plugs but I've no regrets now. You get what you pay for and that is a trip to an aural specialist who makes custom impressions of your ear and sends them to ACS who make very high quality ear plugs that really do the job very well indeed. My only regret - not buying them years ago!! Fantastic product that does exactly what it says on the tin. I work at an airport and regularly walk right next to large aircraft with their bleed air running - one the highest volume and worst noises you might be exposed to and these do the job perfectly. Obviously highly recommended.
