Bought a set of these the other day and gave them a good test today. 70 MPH into the wind and wow they work great. The wind noise is drastically reduced, the music quality is quite good and I can still hear what's going on around me. Sometimes they need to be adjusted, but that's easy enough if you wear a modular helmet. I found the barbed cushions worked best for me as the other ones are too big.
