Etymotic earplugs are actually good value. I owe a website that sells earplugs and I am just finalising buying their plugs as frankly speaking, for what they are, they do represent good value.
As mentioned we do not sell them but there are many good online retailers that do. When we finally do get them ( that should hopefully be within the next few weeks ), I shall arrange for a discount coupon to be posted here for everyones benefit.
Regards. Dave.
