This is the first portable Hi‑Fi player on the market equipped with Cirrus Logic’s CS4308P DAC, now in an advanced dual‑chip configuration (two CS4308P DACs working in parallel).

This innovative architecture ensures outstanding sonic resolution and unprecedented audio power.

The HiBy R6 Pro II integrates independent Class A and Class AB headphone amplifier circuits, switchable instantly with a single tap, to tailor the listening experience to each situation.

• Class A amplification, renowned for its purity, eliminates crossover distortion and offers ultra‑fast transient response. Activating this mode yields firmer control over transitions, with greater density and authority, effortlessly driving full‑size headphones and demanding hybrid configurations.

• Class AB amplification prioritizes power efficiency, extending battery life and reducing heat generation, while maintaining perfect synergy with most IEMs on the market, striking the ideal balance between sound quality and everyday comfort.

The new HiBy R6 Pro II delivers a notable power leap, reaching 632 mW via its 4.4 mm balanced output. As a result, it confidently drives multi‑driver, high‑impedance headphones, ensuring stable performance even in demanding setups.

This capability not only boosts transient speed and dynamic range but also yields richer, more detailed, and punchier playback, combining sonic impact with refined control.

Performance that rivals high‑end desktop gear in a portable form factor.

Specially optimized for the mid‑low frequencies, the R6 Pro II delivers a sound signature that prioritizes listening comfort. Its natural, balanced tuning reveals abundant detail without harshness, achieving smooth, transparent transmission.

The warm texture, with tube‑like nuances, envelops the listener in fatigue‑free immersion—ideal for long, pleasure‑filled listening sessions.

Manufactured with an advanced 11 nm lithography process, this SoC offers a notable increase in compute capability and graphics performance. Combined with HiBy’s vast software‑hardware integration expertise, it ensures outstanding smoothness and instant response, both in music apps and broader multimedia use.

With 6 GB of RAM, the R6 Pro II ensures interruption‑free multitasking and stable background operation, offering instant access to all your apps.

Its 128 GB of internal storage lets you carry your entire library of music and media, ensuring a first‑class audiovisual experience anywhere.

Forget space limits: the R6 Pro II is designed to accompany you both in daily use and more demanding entertainment.

HiByOS is engineered from the ground up for professional music playback, eliminating SRC system‑wide—even in third‑party apps and streaming services—to ensure absolute fidelity to the original sound.

At the same time, it offers a smartphone‑like experience, with smooth multitasking and internal optimizations that guarantee flawless performance in both visuals and audio.

The R6 Pro II 2025’s power section was designed by an engineer with over 30 years of experience in power circuits.

It incorporates high‑flux, high‑capacity inductors with ultra‑low internal resistance and a fully shielded design. In addition, power rails are implemented independently for each critical stage—digital, decoding, preamp, and output—ensuring pure, stable, interference‑free current throughout the system.

The R6 Pro II 2025 supports DSD512, a high‑resolution format that far exceeds CD quality, offering extraordinarily high bitrates and sampling frequencies.

Likewise, PCM playback at 768 kHz/32‑bit ensures an extremely faithful capture of the original signal, delivering more realistic, natural, and detailed sound in every dimension.

The back‑panel design is a true futuristic work of art: waves of aluminum caressing a golden shore under a carbon starry sky.

The chassis features bold asymmetrical lines, where two split curves create visually striking slanted surfaces that also improve grip.

The display is protected with Corning Gorilla Glass, combining scratch resistance with exceptional transparency.

With a 2160 × 1080 Full HD resolution, every image comes to life—whether browsing, watching videos, or gaming, you’ll enjoy rich colors, deep layering, and impressive detail for a truly immersive visual experience.

Control the R6 Pro II remotely over Wi‑Fi from any compatible smartphone or tablet.

It works with the HiByMusic app and also with third‑party apps, offering maximum convenience and flexibility in managing your music.

The R6 Pro II supports full 16x MQA unfolding, which not only increases resolution but also restores the original width and depth of each recording.

This allows genres like jazz, pop, or classical music to sound clearer, more realistic, and more immersive, offering a fresh perspective to rediscover your favorites.

With analog line out, coaxial digital out, Bluetooth, and other options, the R6 Pro II integrates effortlessly into any home Hi‑Fi system.

Combined with HiByCast remote control to manage the entire system, it becomes a new‑generation digital transport, offering unprecedented convenience and versatility.

The R6 Pro II supports the USB DAC function, allowing it to be used as a USB audio adapter for smartphones and computers. In addition, its bidirectional Bluetooth audio turns it into a wireless receiver with high‑quality amplified outputs, offering total flexibility for music playback.
