Background Story
R4's unique design language hails to such elements as cyberpunk, mecha, and space opera. Clear-cut powerful geometric lines cross to form the silhouette of a living, breathing audio machine, with the offset hatch design on the back adding to the motif of a retro classic set in the distant future.
DESIGN CONCEPT
A sturdy lanyard lug coupled with the graffiti-designed lanyard makes for a striking appearance as well as practical usability in outdoor / active scenarios--the quest for an appealing, youthful outlook follows practical considerations to yield a form that is at once instantly recognizable and suitable for a wide audience.
4-Way ES9018C2M
DAC Array
Sporting an unprecedent-for-the-sector set of four separate ES9018C2M DAC chips in a matched array, the R4 has indubitable fidelity in digital-analog conversion, yielding higher resolution and wider dynamic range from any source file, bringing smoother, purer sound. Supporting native playback of DSD up to 256 and PCM up to 32bit/768kHz.
PCM / DSD Dual Customized Conversion Pathways
Separate conversion pathways for PCM and DSD conversion realized for the first time in portable DAPs; separate individually configured / designed DAC chips, LPF and power supplies for PCM and DSD conversion;
Device firmware automatically routes PCM and DSD each to their dedicated pathways. DSD channel more effectively rejects high ultrasonic noise, bringing substantially better listening experience for DSD;
Flagship-Grade Processing Power
Utilizing the Snapdragon 665 SoC with its 8-core CPU, the R4 runs multiple apps smoothly and speedily completes complex music library and audio processing tasks alike, bringing smooth operation and a high quality usage and listening experience to users.
Open Android 12 System
Compatible with all streaming platforms Being based on Android 12 with its excellent compatibility and stability, all mainstream apps and especially all streaming apps run smoothly. Further benefitting from HiBy's software development prowess, timely system updates and function upgrades will bring users a customized, intelligent and intuitive experience in the R4
Class A Amplification for Bountiful Drive Power
- 4 Pieces OPA1652
- 2 Pieces OPA1612
- 16 Pieces Transistor
Utilizing widely acclaimed class-A amplification throughout, the amplifier is composed of four OPA1652, 2 OPA1612 and 16 transistor, and has zero crossover distortion for instant transient response; output scales up to 525mW/322, and distortion can be as little as 0.0005%, yielding a fine sense of power from music as well as exquisite detail.
Flagship-Grade Audio Componentry
