I've been using a Manta Sleep mask (no speakers) for the last year and half, and love it. Unlike the cheap eye mask, it doesn't have an elastic strap that eventually gets out of shape. And it blocks 100% of light for me.
As a side sleeper, I can't use masks with speakers or even long ear plugs, as they put enough pressure on my ear cartilage that they make sleep uncomfortable.
