I've been listening to the MM-1 for quite a few hours and I really like them! I didn't notice the hiss that some owners have mentioned, and while the bass isn't crazy, when I turn the volume to about 75%, my table starts to vibrate a little.
Performance wise, sound quality on the higher registers is very clear and overall it is a great speaker. Some people mentioned that it doesn't play loud, but for computer speakers I think they're loud enough. I'm only listening to them on about 1/3 - 1/2 of the full volume.
But then again, I'm still in the break-in period so things could open up a bit more and sound might change, but anyways...
Great speaker. Saves space. Looks super nice. Would recommend!
