Feature of 4.7INCH Hiby R4 MP4

Cyborg-inspired industrial 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
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
Feature 10
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.

Feature 14
High res audio formats support
DSD256 and PCM 32bit / 768kHz
16x unfold of MQA files, giving master-tape quality audio re-constitution, richer replay of the
sound as intended—it’s a take-you-to-the-concert / studio experience!
MQA (Master Quality Authenticated) is an award-winning technology that captures and reproduces the sound of
the original studio master in a file that’s small enough to stream and download. HiBy is collaborating with MQA
to deliver truely original sound quality to listeners.

User-defined Fn toggle
Unique physical Fn toggle supports custom functions such as button lock and screen flip.

Bluetooth 5.2
Bidirectional Bluetooth supports multiple hi-res Bluetooth codecs such as UAT*, LDAC, aptX, aptX
HD, AAC, SBC etc.
2.4GHz / 5GHz dual band WiFi with stable connection for always-online music.
Support DLNA/AirPlay/WiFi music file transfer.
UAT (Ultra Audio Transmission) is HiBy’s in-house developed all-new Bluetooth audio transmission codec.
Supporting an industry-highest 192kHz transmission sample rate and up to 1.2Mbps Bluetooth bandwidth, this
also can optimize its transmission characteristics according to different music genres, for the highest of audio
fidelity from wireless!
