Do yourself a favor and just get these:
The ones they send out now actually look like this (at least the ones I got):
They're called Silent Ear. Buy the trial pack that has the 3 sizes. I use the smallest ones. The medium and large ones are pretty big.
It says this on the manufacturers website:
SilentEar plugs provide an NRR (Noise Reduction Rating) of 32dB. This is the highest NRR available from any reusable ear plug made anywhere in the world today. To achieve more protection than you get from SilentEar, you would have to wear a pair of NRR 32 earplugs underneath a pair of hearing protection ear muffs. SilentEar ear plugs are designed to offer the ultimate in protection, and may not be appropriate for situations where only a small amount of noise reduction is needed.
When I read this after using them, I was kind of surprised, since when I have them in I can have a conversation with someone almost normally. To me, they really block out mainly the harmful frequencies, while keeping everything else at a pleasant level.
They're reuseable. Just wipe em off when you take them out. The fit down into your ear, with just the 3 little flap things out of your canal so you can get them out. They're comfortable. They really knock down any sort of wind noise. I have also had no problems with them coming off while taking on or off my helmet.
They also come with the nifty carrying tube thing.
You'll spend less than $25 or something to you door for the 3 different sizes pack, and you shouldn't have to buy any earplugs for a long long time. I've used mine since like April and they're like brand new.
They are SOOO much better than foam earplugs, and if I would have known about how easy and how well these things work, I would have bought some a long time ago.
Your results may vary.
