I've searched the forums about this and either the search function isn't working properly, or I'm the only one who suffers from this

I love the sound of many of the current IEMs with hybrid driver arrays - I think dynamic drivers sound great for bass reproduction and I think it's a fairly standard view.
However, I absolutely cannot tolerate IEMs outdoors in all but the most perfectly still conditions. The slightest breeze (even the breeze you generate yourself merely by walking) seems to swirl around in the bass port and completely overpower the sound of the music.

Is this something everyone else suffers from?
I don't regret my U18t purchase at all - but I had to eliminate almost all of the current range of TOTL models as soon as I saw that little port poking its head out of the lovely shells that encase the drivers.

Is there no way to port the bass on the side of the shell facing towards the skin, or maybe make a slightly curved chamber outlet to reduce the impact of winds and breezes?

+1 to this question, thanks for posting it. I face the same issue with wind blowing on the bass ports and dampening the subbass.
I haven't found a solution for it except to use these bass ported IEMs in less windy places or to use IEMs without bass vents in windy conditions.

I assure you, you aren’t the only one who suffers from this. Perhaps you’re just more sensitive to it than a lot of other people. Fortunately, it seems like the newer hybrid/DD IEMs are placing the vents on the inside (ear side) or under the plug, facing forward.

One thing that I find makes a big difference is how the DD communicates sound to the nozzle. All single DD IEMs and many hybrid IEMs have the IEM shell serve as a sound chamber, and thus air/sound from the vent can communicate sound directly thru the shell into the nozzle, and into your ear. Some other hybrid IEMs, including most CIEMs (I think) use tubes to connect all of the drivers to the nozzle. It works for CIEMs b/c the drivers don’t depend on the shell to affect the sound, since the shell will vary based on individual ear anatomy. The point is, in this design, the drivers are all connected to the nozzle via tubes, and the vent for the DD still alleviates pressure for the driver, but doesn’t really connect/communicate directly with the nozzle. Isolation is a lot better with these types of IEMs, for the most part. I have both a CIEM and a UIEM with this type of design, and I can achieve the same levels of isolation that I can with my all-BA IEM.
