DPPU adapts a dual high-density battery customized power system, designed for High-Fidelity while ensuring digital and analogue power separation to eliminate digital circuit noise from the source, similar to an enhanced DAC + Amplifier system but with a minimal path and hard soldered joints with no compromises.

We are inclined to design our audio circuits on the basis of professional audio circuit design, and we make the logics of technology work in harmony with music sensibilities. In the process of R&D, we make every effort to perfect the DAC AK4497 and AMP circuit.

Our software system employs the Touch & Feel Algorithm, which can not only adjust the volume comfortably, but also evade channel deviation in different volume ranges that are experienced by long-used buttons.

Persevere in improving the CMF implementation so as to bring the beauty of the design to life.

With precision machining on aviation grade, light-weight aluminum alloy, all the efforts provide Honey h1 with effective isolation against EMI disturbance for cleaner recording background
