Excellent thread Dave, coincidentally I was just about to post a thread today on this very topic because I accidentally discovered something that has completely revolutionised my relationship with ear plugs.
It's especially important if you wear an open face as I do, I recently bought a s/h full face helmet because it just gets too much if it's windy, however I just can't wear them, hate them to death, I don't know how anyone enjoys riding with a full face. So the most covering I get is a clip on visor for my open face, which is this style the RXT Metro
https://www.rxthelmet.com.au/product/metro-matt-black/ But I think I'm going to upgrade to the Metro Retro
https://www.rxthelmet.com.au/product/metro-retro-white-silver/So you can see that wind noise is pretty tough. I'm also already losing some hi frequencies, even though I've always been careful, whenever I went to a gig of any kind if it was loud I'd at least pop into the toilet and wad up some toilet paper, anything to deaden the sound.
So I take it very seriously, and it's an all or nothing situation, if it doesn't seal completely then it's almost as good as useless. For silicone seals it has to be very soft and flimsy, I've only ever found one set that ever fit well enough to seal properly, and that was the philips SHE9550
https://www.goodgearguide.com.au/review/philips/she9550/268996/ I've bought a few sets of these after they were discontinued, for about twenty bucks. They are the best sealing earbuds I've ever had and I cannot get them any longer. I used the largest size that they came with even though I have small ears. The headphones themselves are awesome.
What I'm about to say next is quite simply unbelievable, but here goes. OK I thought I can't get these great headphones any more, but I shall purchase some other Philips SHExxxx headphones because they'll use the same replaceable sets of tips won't they.
You'd think so, I bought one after the other, the largest ones are too small, none of the Philips headphones use that particular size any more, all it is is a bit bigger than the biggest size. It's freaking unbelievable. After giving up in frustration I bit the bullet and spent a couple of hundred on some Sonys which in 2014 were their best buds
https://www.amazon.com/gp/product/B00931SBS0Nope the largest tips on the Sonys were too small to seal properly and reliably, you'd have to twist and finagle them then you'd move your mouth and they'd shift, and if they don't seal these very expensive buds sound like a $10 pair.
OK the search continued maybe something like the triple seal that etymotic make
https://www.etymotic.com/consumer/earphones/er4-new.htmlBy this stage, I'm not looking to spend 300 bucks on earbuds, I was thinking that the triple flange that Etymotic use on their top models as well as the cheaper ones must be a good if they can sell their buds for hundreds of dollars. So I went onto eBay and found some triple flange plugs
https://www.ebay.com.au/itm/1-pair-Silicone-Ear-Plugs-Anti-Noise-Snore-Earplu...At one buck a pop I took a chance and ordered a half dozen, and they come in a nifty little hard case, after all when you pull them out for a coffee stop you don't want to stick them in your jeans.
OK these did do the job, they are a very soft and pliable silicone. Now we start to get into the meat of this post but I did want to give the preamble to show the full journey. I've tried some locally made more expensive ones in this same style but these blue cheap ones are better, due to softer and thinner flanges.
I quickly discovered that in order to make them seal absolutely perfectly they need to be lubricated with water. And they worked pretty good but for long journeys they began to get a little sore. I discovered that I could shorten the stem and that helped.
But I wanted something for longer journey's that were comfortable. I haven't tried every brand of plug but I'm certain that I have found the best plugs you can get, the Hearos. The 3M are supposed to be good but they don't have the buttery softness of the Hearos I didn't know what size to get so I got two sizes the blue ones and the flesh coloured ones
https://www.ebay.com.au/itm/New-Hearos-Ultimate-Softness-Ear-Plugs-NRR-32-14-...https://www.ebay.com.au/itm/Hearos-Original-Formulation-Xtreme-Protection-Ear...They are wonderfully soft and comfortable, I cannot see how they can be improved, because their formula is perfect for closed cell and ultimate comfort.
The only difference is in their size, the flesh ones are smaller, they both work extraordinarily well and if you install them perfectly they do make a perfect seal and their softness makes them super comfortable. So that's what I've been using for a while and let the blue triple flanged sit in my draw. But the Hearos have some practical disadvantages which are the same for all foam plugs, and that is, 1 they take a while to insert correctly you have to roll them and get them cleanly in the canal before they begin to expand, this is quite tricky in hot weather because they puff up very quickly and if you don't do it right it's no good, and 2 you really need to put a fresh pair in every time you remove them.
So it's usually a few minutes to get them done right, first one then the other. Now a couple of weeks ago I have moved to a new place which is in the very best motorcycling area of Australia, if you want roads as well as scenery this is motorcycling heaven. It's an eight kilometre ride to the local shops at Maleny QLD, and this ride is so luxuriously beautiful that I'll ride to shops at any excuse, often taking an extra long detour.
This now revealed the problem with the Hearos, they start to become a pain in the backside, because it's fine to take a few minutes to get it right for a big ride, but having to install these, take them out and then reinstall every 10 minutes to go to the shops is tough. Not only that but you don't really want to put them back in, so I have a couple of containers of them and when I take them out they go into the used container and I put fresh ones in.
Then when I have a bunch of used ones I wash them in warm soapy water and let them dry out for a few days and they are back to new. You can see where I'm going with this, it starts to become very very tedious.
Hang in there because we're about to get to the good bit, and I'm going to bring Covid-19 into the picture.
I thought I'd give the old blue triple flange another go because they'd be much easier to manage as well as wash and seal for short journeys.
Now as I said I used to lubricate them with water and I started carrying water around with me for this purpose, I considered for about 2 seconds the possibility of using saliva to lubricate them but I canned that idea before it even had time to settle in my brain. Bacteria in the ear doesn't sound good.
Also rolling those Hearos with hands that are not scrupulously clean, seems also a bit wrong. By now we are in the middle of the Covid-19 storm, and I go to the supermarket and at the entrance there's some hand sanitiser, and I used it and it was a very slippery gel, it's also a disinfectant and it dries fast. Suddenly it all came together, not water, how about using the blue triple flange with hand sanitiser gel as the lubrication.
Bingo.
I'm using this

but anything that is a gel type hand sanitiser would work. My first thought was to use a water based sexy time lubricant, but I didn't bother because it's obviously even better to have something that disinfects your hands as well as the plugs if you're going to stick them in your ear.
I've been using them now for a week and it has utterly, completely and totally transformed my riding. When they are in properly, it's like riding a luxury BMW with one of their super windshields.
I ride a GS500 and the engine sounds like a Rolls Royce with these plugs in and sealed, the mad deafening wind rush, sounds like the gentlest of summer breezes lightly caressing you. I ride better too because instead of hearing the engine screaming at 7000 rpm, it sounds more like a muffled Ferrari with a nice growl that you can't normally hear. So I work the rpm better now, which makes the whole bike feel more responsive.
One problem is that I have to keep a closer eye on my speed because it's very easy to find yourself creeping up to 100kph or more in an 80 zone, because it feels like I'm riding at 60kph. Even a windy day it not problem, it's makes me crack a huge smile every time I"m on the bike now. And with the gel as lubricant it only takes seconds to get them in.
So the big secret is to lubricate your earbuds whatever type you use whether connected to a sound system or not, with a gel hand sanitiser.
I put a dab of gel on the back of my hand and then twist those blue triple flange plugs in the gel to coat them properly, they slide right in (oo er) and they are always clean. I go to the shops and put them in their little hard shell and when I come out it's only a few seconds to install them.
Could be a problem with music buds though because of the gel. But this post is only about sealing your ears from the wind. Perfectly.
Occasionally I'll be riding and the seal with break just a little tiny bit, they still work well but you notice the difference instantly. It's worth it to just stop the bike and re-apply some gel, if that happens.
Regarding the Comply tips, I find them very intrusive and not very comfortable as their advertising says.
These blue triple flange plug plus gel is life changing.
Here's some local scenery.

Thats the Glasshouse Mountains in the distance and wherever you go around here they are looming up at you in the most unexpected places. They don't look that impressive on the photos because it's an iPhone and therefore wide angle and makes them looks very tiny but they are huge volcanic plugs.
