What are the best ear buds or pods to use for the purpose of blocking wind noise?

Though I almost never listen to music while I ride, I always have my buds in, so I can hear the ringer on my iPhone. I am on-call 24/7.

With or without earbuds in, I get the problem of wind-roar beginning at just about anything over 12mph or so, which even if it wasn't just plain annoying to listen to, I think contributes to mental and physical fatigue on an all-day ride, and can be almost painful on long, fast descents (I am such a delicate little flower ).

I've had good results blocking wind noise by wearing a balaklava or wide ski headband over my earbuds, but this is way too warm for most of my riding season. The type of bud that fits like an earplug seems to work OK sometimes, as long as they stay tight, but they usually sweat out, and I'm constantly having to shove them back in. The fact that I have smaller than normal ear canals is not helping here.

I noticed Yurbuds "Ironman" earbuds advertised for running/skiing/biking etc., so I bought some of those, and to my great disappointment, they made the wind roar MUCH WORSE than not having anything in my ears, and in fact much worse than any other cheap or expensive ear bud I've tried. (Side note: music-wise, they actually sound pretty good when stationery, but that's not what I bought them for).

Anybody have any recommendations for better wind-blocking ear buds, or a for a workaround I can use with my iPhone buds that doesn't involve swaddling my upper head with heat-trapping fabric?
