Read that long thread on hearing loss and earplugs and suddenly got a bit safety concious I just bought loads of these moldex pura-fit plugs from ebay (dirt cheap - less than £5 for 16 pairs)...anyone tried them and know if they're any good?
I found myself to dislike foam plugs when using them for extended periods of time. They get the job done well, but I began feeling discomfort from them after regular use. I changed to a style similar to these Thankfully my mom works for a large scale chemical manufacturer and can get different types of earplugs for free. I suggest, when you're able, trying out different types to see which you prefer best. Eventually I would intend to buy a custom fit pair, but bills first. Thankfully, hearing protection is very cheap. I'll never understand why less people take advantage of it.
I guess it depends on what you're subjecting your ears to... but the foam plugs are fine for most situations you'll realistically be getting into.
