Pros

  • Best-in-class sound: 7mm TrueResponse driver, neutral tuning, wide soundstage
  • aptX Lossless (16-bit/44.1kHz) + aptX Adaptive + LDAC + AAC + SBC
  • Excellent ANC: adaptive, wind-noise mode, adjustable transparency
  • 30h battery (ANC on), 42h (off) — class-leading
  • IP54 (buds), wireless charging, multipoint (2 devices)
  • Smart Control app: 5-band EQ, Sound Zones, Sound Check hearing test

Cons

  • Bulky case (72 x 48 x 32 mm) — doesn't fit coin pocket, heavy (65g)
  • Fit: large nozzle, no wingtips — small ears may struggle
  • Touch controls: small surface, occasional misfires
  • No spatial audio / head tracking
  • $299 MSRP — premium pricing

Who Should Buy This

  • Audiophiles wanting wired-like sound in true wireless
  • Snapdragon Sound phone users wanting aptX Lossless
  • Battery life maximizers (30h ANC is class-best)

Our Verdict

The **Momentum True Wireless 4** is the **sound quality king of TWS**. 7mm TrueResponse + aptX Lossless + neutral tuning = closest to wired IEM experience. ANC is excellent, battery is class-leading. But the **bulky case**, **fit issues for small ears**, and **$299 price** limit its appeal. If sound > everything else, and you have a Snapdragon Sound phone, this is the endgame TWS.
