They are obviously using a simple quartz wafer crystal oscillator to create two separate voltages to represent 1 and 0. If they followed the usual then that would be 5 volts would be 1, 0 volts would be 0 and a threshold of about 2.5 volts. The crystal works by a voltage being applied this will cause they crystalline structure to be warped then snap back at a rate relative to size and voltage. This will case the voltage to go to a positive to a negative back to a positive voltage. They will shape the resulting it to a square wave, which looks like a square or rectangle. Then it will be rectified (cut off the negative portion of the wave). Now to step to into the world of computers, to get the frequency required for what we need we will put this signal into a frequency multiplier. When we over clock a computer the multipliers are the parts we modify which is why the voltages, amps, and so on are increased. Now for the crystal if we want to increase the frequency we decrease the voltage. There is a minimum voltage though.
The whole line-up consists of the $60 Amps in-ears and $100 Tracks on-ear headphones, which both also come in slightly souped-up and pricier HD variations at $100 and $130, respectively.
