They go great with my white YU2 speakers. They help reduce energy loss from my desk surface and direct the tweeters toward my head, which improves the sound quality a bit. To be honest they seem a bit flimsy and I can't help but think they should be around $10-$15 or less. Or they should just come with the YU2, although separate access is probably fine for anyone buying them for other speakers. I would recommend that you go with the black ones, not the white ones. The white is a little different from the glossy Kanto white, and the black goes well with the black speakers.
