Perhaps I'm just a delicate flower, or perhaps the amount of attenuation I'm seeking is much greater, but of all the different ear plugs I've tried, I've found most of them to be total junk.
Back in t'day, I was using
Doc's Pro Plugs. These are pretty comfortable, but also not super effective at blocking sound despite the hype. The Kraton rubber softens over time, and then goes super comfortable before going super gungy and falling apart. I wore them a lot on my first few tours with my Pan. But my most recent pair (that I got last year) are stiffer and really not comfortable at all. After my first pair of Pro Plugs gave up the ghost, I started using
Alpine MusicSafe ear plugs with the highest rated filters. The filters are long and thin, and the ear plugs are the usual two-cup, cone shaped style. I found I had to fairly jam them in to get them to block sound reasonably effectively. And then after a couple of hours my ears would start to hurt. But worth it for the basement rock gigs and Rush concerts.
So, I got mouldings taken and bought a pair of
Ultimate Ear squidgy ear plugs.
Now I knew what -30dB felt like! What a difference! I wore them on pretty much every motorbike ride for 15 years. In fact, the only reasons I stopped wearing them were that a) 15 years is probably too long to expect your ears to be the same shape, and I think mine weren't by then, and I was finding they started to hurt quite quickly; and b) I got the Cardo for my helmet and needed to, you know, hear stuff.
Given how many people seem to really rate Howard Leight foam plugs, I bought
a variety pack that includes Laser Leights, and I tried most of them. I didn't find them any better at blocking sound than standard
3M Classic 28dB ear plugs, which also weren't very good. In fact, almost all the foam ones hurt my ears after an hour, sometimes less. So I tried
Clear Ears, recommended by a colleague and apparently good for sleeping and swimming. They were really comfortable, but I didn't find them to be very good at blocking sound, and they had a tendency to get dislodged when I put my helmet on or took it off. I still ended up with the loud rustling-whooshing sound of air streaming past my helmet, and the throaty roar of Mr Remus's finest exhaust or the turbine whine of a Pan European.
By now you might be thinking I mustn't be inserting foam ear plugs correctly. I know how to roll foamies thin, and to pull my ears up or back, or up and back, to open up my ear canals, and to let the foam expand once in. But my ear canals are an odd shape: tall and narrow. They're also not the same left and right. That I know for sure because that's the shape of my Ultimate Ear ear plugs, which themselves were always tricky to put in fully. I also really don't like things pressing on my ears if I have ear plugs in,
especially the actually-quite-firm Ultimates, so the bulge of the thin Cardo speakers won that argument.
So I bought a pair of
Eggz, which are basically the same shape as the Alpines, but you get two sizes in the pack, and just the one set of filters. Well, I wanted to like the Eggz, because my bestie uses those and find they work really well for her, but tall and narrow ear canals simply don't get on well with the rather large diameter filters. So my ears still hurt after half an hour. But I persevere with them because they do block sound quite well if I jam them in. The rubber is slightly stiffer than the Alpines which are so soft they come with a special poker-inner to get them in properly.
By this point I was despairing and running out of options. What I needed was something squidgy and dense like the Ultimates, but softer and more malleable. What about wax or silicone ear plugs like for camping or hostels where your bunkmate is snoring like a train? Well, I bought a pack of
Knoxzy silicone ear plugs and experimented over a few rides. I liked them a lot. So I did some rides on my Africa Twin with the loud exhaust and I liked them even more. Sure, you have to warm them a little, and find the right kind of shape, and squidge them in, and the increased air pressure hurts a little bit in the process, but they seal well and are completely compatible with my Cardo if I put my not-a-phone GPS on maximum volume. Apart from one day when I pillioned on bestie's little Royal Enfield on puttery wee roads, I used them for the whole of my 1500 mile tour. Each pair gradually picks up oil from my ears but they last quite a long time so the box will last me quite a while.
