"This pioneering achievement for the first time in the history of sound reproduction, delivers a small form factor speaker that is capable of reproducing hi-quality sound throughout the full audible spectrum (and beyond)."

Wow!! That's a single headphone speaker chip producing 20Hz to 20kHz. The full spectrum that human ears are capable of hearing. Nothing else comes close to this. If you have the cash, then this is the only headphone speaker that you want to have. No wonder they switched development priority to these Gen 1 chips. I can see why they don't have to market these.
