soundKey is an award-winning revolution in mobile music. Hi-Fi streaming services like TIDAL mean fantastic quality is available to subscribers, but phones lack the necessary hardware to get the best from this data. soundKey unlocks that data, using our years of expertise in high-resolution DAC and amplifier design. Cyrus quality audio is now available to everyone.

I see it a step up from $9 dongles but the $99 price is hard to swallow.

The Topping D90 produces lowest noise and distortion [of the] 220 DACs [I've] tested so far.
