Quick Read

FiiO M23

The M23 is FiiO's $699 midrange-plus Android player pairing a flagship AKM DAC stack with THX AAA 78+ amplification good for roughly a watt balanced, plus practical extras like a desktop mode that runs the player off wall power to spare the battery. Approved reviews agree it punches above its price on scale: MajorHiFi hears a wide, articulate presentation that stands confidently next to some thousand-dollar players, and Headfonics rates it a competitive, smoother-sounding update over the M11 Plus ESS with genuinely useful new features. The consistent criticism is the FiiO house smoothness: timbral edges can feel rounded off, which flatters harsh recordings but can read as slightly veiled next to more incisive rivals.

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

  • Expansive, wide-scaled sound that competes above its price class
  • Near 1W balanced THX AAA 78+ output drives demanding IEMs and many headphones
  • Desktop power mode and modern conveniences add real daily value

Weaknesses

  • Signature smoothness can veil timbral detail and transient bite
  • Android 10 base is older than same-price rivals
  • Not the pick for listeners wanting maximum incisiveness and energy

  • 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
