Hiby R3 Pro II Silver - Hi-Res Player

An 86.9 × 60.6 × 14.5 mm aluminium chassis houses the dual ES9219C DACs and a new X1600E SoC, capable of 384 kHz/32-bit PCM, DSD256 and 16× MQA decoding. The balanced 4.4 mm output delivers 380 mW @ 32 Ω - four times the power of a conventional player - while the 2 000 mAh battery provides up to 19 h of music with the 3.5 mm jack.

Dual ESS architecture and dedicated clock

The two ES9219Cs work in fully balanced mode with independent clocking to minimise jitter and crosstalk; the result is a THD+N of less than 0.001 % and 122 dB SNR, preserving micro-detail even at high volume.

Full connectivity in your pocket

2.4 GHz Wi-Fi enables AirPlay, DLNA and HiByLink; two-way Bluetooth 5.1 supports UAT, LDAC and aptX to transmit or receive Hi-Res sound wirelessly. The USB-C port functions as a DAC/AMP or coaxial S/PDIF output, and the microSD slot supports up to 2TB.

Touch interface and mechanical wheel

The 3.2″ (320 × 480) IPS display is smoothly responsive thanks to HiByOS and navigation is enhanced by the aluminium wheel, ideal for one-handed operation or in your pocket.

Autonomy and fast charging

With low gain and 3.5 mm jack it reaches 19 h of playback; balanced mode sustains 16 h. Full charge takes less than 2 hours with a 5V/1A USB-C adapter.

Lightweight and ergonomic construction

The 118g weight and rounded corners facilitate continuous use, while the CNC-milled frame protects the circuitry from electromagnetic interference.

Comparison

The HiBy R3 II 2025 improves on the original R3 II by doubling internal memory, incorporating the X1600E SoC and adding 40% more battery life. Compared to the Sony NW-A306 (≈1 mW, no balanced output) it offers 380 mW and MQA compatibility; compared to the Shanling M0 Pro, it maintains similar size but adds Wi-Fi, 4.4 mm and native streaming. In its range, it combines the power needed for demanding IEMs with an ultra-portable form factor and connectivity that rivals higher-priced models, making it the best value option for Hi-Res audio in 2025.
