I found that closed buds (ones that seal in the ear) are the best for this. If I used open, there was so much wind noise that I had to crank the volume to max and probably damage my hearing to hear what was going on. With in-ears, very little wind noise, I can keep the volume down.

Of course, I only wear one at a time.

You may also want to look on Amazon for "Slipstreamz" products. they have a little thing that clips onto the helmet strap and directs wind around your ear.
