These work well, I put the speakers from my Sena into them and the music was clear and I was able to adjust the volume to a very loud level. I don't think any speed would have drowned out the sound. My only complaint was they are very substantial, this may prove a positive when the weather gets cold, but they gave my half helmet the feel of a 3/4 helmet because of the way they fit on my face. I would buy them again.
