R4’s Unique Design

R4’s unique design language hails to such elements as cyberpunk, mecha, and space opera. Clear-cut powerful geometric lines cross to form the sihouette 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.

A sturdy lanyard lug coupled with the graffiti-designed lanyard makes for a striking appearance as well as practical usability in ourdoor / 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--ultimate product of budget DAP arms race

Sporting an unprecendent-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 prowness, 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

Utilizing widely acclaimed class-A amplification throughout, the amplifier is composed of four OPA1652, 2 OPA1612 and 16 triodes, and has zero crossover distortion for instant transient response; output scales up to 525mW/32Ω, 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

Flagship-grade Audio componentry--28 high-precision tantalum capacitors bring finer power supply ripple rejection for blacker background and greater detail.

3.5mm SE and 4.4mm balanced audio ports make for a wide range of suitable usage. Almost any earphones can be plugged in and the device is well tuned for popular music.

Dual independent crystal oscillators, FPGA clock algorithm

Utilizing dual independent audiophile-grade crystal oscillators at 45.158MHz and 49.152MHz effectively reduces phase noise and jitter, providing provides high precision timing for all audio events in your music.

Large screen, high res, stop press

Large hi-res 4.7” Sharp LCD screen with 24 bits / 16.7 million colours, see the music world through a wider clearer lens. 720x1080 resolution

Long run time, high battery capacity

4500mAh battery yielding up to 11 hours run time on 3.5mm SE output, over 675 hours standby, as well as long run time under heavy screen / CPU / wireless use.

The ever-reliable HiBy OS

The HiBy OS is an in-house developed system architecture developed by HiBy targeting professional HiFi audio equipment. Optimized / novel components include system core, decoding system, audio DSP algorithms, media library management, external drivers / plugins etc. optimizing the player for lossless hi-res audio from the ground up. HiBy OS is synonymous with audio quality, flexibility and reliability.

True systemwide bitperfect audio

With the Direct Transport Architecture of HiByOS, avoid Android resampling of audio system-wide, simply plug earphones directly onto the R6 for bit perfect audio even with third party streaming apps. Also enjoy bitperfect audio with USB audio output even with third party apps.
