Quick Read

HiBy R4

The R4 is HiBy's $249 entry into real-Android DAPs: open Android 12 on a Snapdragon 665, quad ES9018C DACs with separated PCM and DSD pathways, and a Class-A analog stage. A spec sheet that simply did not exist at this price before it. Approved coverage from Headfonics and Headfonia agrees on the verdict: an excellent middle-of-the-road player whose software features and add-ons can raise its quality well above the sticker, with a slightly warm, musical Class-A flavor. The tradeoffs are equally consistent: a chunky, love-it-or-hate-it retro design, battery life that pays the Class-A tax, and technical performance that is good for $249 rather than good outright.

HiBy R6 Pro II

The 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

  • Open Android 12 with a capable Snapdragon 665 at an entry price
  • Class-A amplification gives a warm, engaging flavor unusual in the class
  • HiBy's software stack (MSEB, plugins) adds genuine tuning flexibility

Weaknesses

  • Battery life suffers from the Class-A output stage
  • Bulky, angular retro styling divides opinion
  • Absolute resolution and staging are entry-tier despite the features

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
