These are some speakers from Greensound Technology, and, as you can see, they are partially made from glass. They have nothing to do with the USB Wine Glass speakers.
They even have a glass-encased subwoofer, and they can handle 25 watts of power and go into the 300HZ-15kHz frequency range. They are also good enough for 360 degrees of sound.
Apparently, the shape of these speakers with the transparent crags are inspired by glaciers.
