Other than the in-ear, custom-cast, monitor earbuds, nothing is going to block wind noise as an earbud. Of course, successfully blocking wind noise with an in-ear earbud will also block all other noise arriving by air.

Provided you are not overly embarrassed by appearing nutty while you ride, consider a blocking shape attached to your helmet strap. There are commercial versions like slipstreamz (a plastic clip), but in my experience nothing disturbs and minimizes the noise like a soft shape on your helmet strap that maintains contact with your face. Orientation is very important to the performane of any device like this. It may be easier for me on the resumbent as my head is more or less already straight up where the wind somes in at right angles. If you ride head down you may have to reposition this kind of shape. The look-before-you-buy test is to lay your index finger on your cheek, behind your eye but in front of your ear while you are riding and see if the wind noise disappears for you or not.
