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.

Sony NW-WM1AM2

The NW-WM1AM2 is the aluminum half of Sony's flagship Walkman pair: the WM1ZM2's architecture (S-Master HX digital amplification, premium passive components, Android with the full streaming ecosystem) at a third of the gold model's price. The long-running Head-Fi ownership threads consistently describe it as the sane flagship Walkman: rich, spacious, refined Sony house sound, superb build, and up to 40 hours of high-res playback, sharing most of the range-topper's specification. The recurring caveats: S-Master output power is modest for a flagship (IEM-first, like most Walkmans), Android drains harder than the old Walkman OS, and the price still buys a lot of Chinese competition on raw specs.

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
