Unveiling the RS8 II: HiBy's New Pinnacle in Portable Hi-Fi Technology

On October 30, 2025, the audio industry was abuzz with the announcement of HiBy's newest flagship portable Hi-Fi player, the RS8 II. Designed to elevate the standards for high-end portable music devices, this player integrates the latest audio advancements and a deep understanding of market trends.

High-Performance Audio Integration

The RS8 II is powered by the Qualcomm Dragonwing QCS8550 processor, which is part of the 8th generation platform, combined with HiBy's third-generation DARWIN audio architecture. This powerful duo, supported by AdaptiveAMP technology, allows for dynamic class A/B amplification with 64 tuning levels, achieving a remarkable total harmonic distortion plus noise (THD+N) rating of just 0.0008%. The combination of a CPU, GPU, NPU, FPGA, and DSP network, along with a precisely engineered R2R resistor array, ensures accuracy in high-resolution audio reproduction.

The RS8 II includes an innovative audio tone simulation called Sankofa AI, enabling consumers to experience sound profiles reminiscent of classic audio sources such as minidisc, CD, cassette tapes, and magnetic tapes—all with free updates to personalize the Hi-Fi experience further.

Stylish Design and Superior Portability

In terms of aesthetics, the RS8 II showcases a monobloc aluminum chassis accented with a glass back, geometric lines, and three-dimensional cuts to create a distinctive style. The rear of the device is embossed with “RS” and “DESIGNED BY HIBy”, while hexagonal side buttons symbolize the Darwin architecture. Weighing in at 425 grams, this player successfully merges sophisticated performance and portability.

The player features a 5.5-inch HD display with a resolution of 1080 × 1920 pixels and is equipped with a 46.8 Wh battery that supports rapid charging at 80W via PD3.0.

Connectivity and Versatile Outputs

HiBy's RS8 II excels in connectivity, supporting Wi-Fi 7 MIMO and Bluetooth 5.3 with AptX Adaptive and AptX Lossless compatibility. Audio performance is further enhanced by femtosecond oscillators at 45.1584 MHz and 49.152 MHz, capable of handling DSD1024, PCM 1536 Hz/32 bits, and MQA 16X formats. The Direct Transport Audio (D.T.A.) architecture enables high-resolution playback from third-party applications, bypassing Android's sample rate conversion.

Output options abound, with a 3.5mm balanced output, a 4.4mm headphone output, a balanced line output, a Type-C digital audio output compatible with SPDIF coaxial cables, USB audio input/output, and a pioneering I²S interface designed specifically for portable players. This extensive array of connections dramatically amplifies potential use cases for users.

Setting New Standards in Hi-Fi Listening

With advanced tone simulation, ultra-low distortion rates, and efficient energy management, the RS8 II offers an unprecedented high-fidelity listening experience, setting a new benchmark in the portable Hi-Fi sector.
