Quick Read

HiBy R3 Pro II

Approved community coverage around the current R3 II and R3 Pro II naming cluster paints the device as sonically decent but operationally frustrating. Head-Fi reviews praise its compact size, acceptable battery life, and good value sound, yet repeatedly criticize the dim display, buggy software, freezes, and lack of meaningful firmware improvement. Reddit discussion around the R3 Pro II label points in the same direction: buyers are drawn to its form factor and build, but worry about long-term polish. The result is a very small DAP that can sound good enough for the money while still feeling held back by software execution.

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.

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
