HiBy R6 Pro II
Open pageThe R6 Pro II is HiBy's $749 Android mid-fi player built around dual AK4499EX DACs with a discrete I/V stage, dual NDK femtosecond oscillators, and switchable Class-A/AB amplification: spec-sheet decoding (native DSD1024, 32bit/1536kHz) that led the market at launch. Headfonics hears a slightly laid-back, smooth signature tuned for IEM precision rather than raw wattage, recommending it as a big-screen streaming-first player or a refined IEM source. The tradeoffs: Class-A mode taxes battery and heat, output power targets IEMs not full-size headphones, and the relaxed tuning is a flavor choice that detail-first listeners may find polite.
Strengths
- Dual AK4499EX with discrete I/V and femtosecond clocking at $749
- Class-A/AB switching lets you trade battery for refinement
- Smooth, laid-back tuning that flatters long IEM sessions
Weaknesses
- IEM-first output power: full-size headphones want more
- Class-A mode runs warm and shortens battery life
- Relaxed signature can read as polite next to energetic rivals
