The player is powered by the Qualcomm Dragonwing QCS8550 (8Gen2 platform) and the upgraded third-generation DARWIN audio architecture, paired with AdaptiveAMP, offering dynamic A/B-class amplification with 64-level adjustability and THD+N as low as 0.0008%. Its powerful CPU+GPU+NPU+FPGA+DSP array combined with a precisely matched R2R resistor network ensures accurate high-resolution audio reproduction. Sankofa AI tonality simulation allows users to enjoy sound signatures modeled after classic audio sources such as MD, CD, cassette, and reel-to-reel tape players, with free updates for a personalized HiFi experience.

In terms of design, the RS8 II adopts a unibody aluminum chassis with a glass back, geometric lines, and three-dimensional cuts for a distinctive appearance. The rear panel is engraved with RS and "DESIGNED BY HIBY," hexagonal side buttons symbolize the Darwin architecture, and the multi-faceted rotary knob reflects light like a diamond. At 425g, the player balances flagship-level performance with portability.

The RS8 II features a 5.5-inch 1080×1920 HD display and a 46.8Wh battery supporting up to 80W PD3.0 fast charging. Wireless connectivity includes Wi-Fi 7 MIMO and Bluetooth 5.3 (compatible with AptX Adaptive & AptX Lossless). Audio performance is enhanced by 45.1584MHz and 49.152MHz NDK femtosecond oscillators, supporting DSD1024, PCM 1536kHz/32bit, and MQA 16X, and Direct Transport Audio (D.T.A.), which bypasses Android system SRC for high-resolution playback from third-party apps. Output options include 3.5mm PO/LO combo, 4.4mm BAL Phone-out, 4.4mm BAL Line-out, Type-C digital audio supporting SPDIF coaxial, USB Audio In/Out, and the first-time portable player I²S interface, greatly expanding connectivity possibilities.
