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.

Sony NW-ZX707

The NW-ZX707 is the modern mid-tier Walkman: Android streaming, Sony's warmest build quality in the line, and the signature house sound. Rich, lush, and musical rather than analytical, with a clean black background and tight, layered bass. Long-running Head-Fi ownership threads consistently rate it a clear step over the ZX507 in soundstage, control, and battery, and the best-built DAP Sony has made in this class. The one structural caveat every buyer must know: regional variants differ, and the US/EU model ships power-capped with no high-gain option, so demanding headphones are off the menu. This is an IEM-first player. Factor in the brand premium and it scores on charm and refinement, not spec-sheet muscle.

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

This is an IEM-first player. Factor in the brand premium and it scores on charm and refinement, not spec-sheet muscle.

Strengths

  • Signature Sony musicality: lush mids, tight layered bass, silent background
  • Class-leading build and superb real-world battery life
  • Meaningful upgrade over the ZX507 in staging, control, and speed

Weaknesses

  • US/EU variant is power-capped with no high gain: IEMs only, effectively
  • Not a detail-first presentation; analytical listeners will want more incisiveness
  • Brand premium against spec-heavier Chinese rivals at the same price
