With most speakers, you can see how the volume is set by looking at a little knob. Pretty traditional! Not the case with the Vol Portable Speakers, which move from tall and skinny to short and squat as you adjust the volume.
There's nothing too crazy going on here, just a sheath that goes over a cylindrical speaker that can be pushed down to adjust the volume. But it's a new and unique form factor, and in a sea of computer speakers that all look the same, that's pretty cool.
