Sound quality massively outperforms the price tag. Multiple users say the Quark's balanced, smooth tuning rivals far pricier IEMs, with one directly comparing it favorably to the Blessing 2 and another preferring it over the SSR. Vocals and mids are described as clean and unemphasized in the upper-mids, avoiding harshness. However, some find the mids too thin for male vocals, and bass is called non-existent by rock listeners, showing the tuning favors calmer, vocal-forward genres over bass-driven ones.

Comfort and portability make it a reliable daily companion. Its small, bullet-shaped form factor is repeatedly praised for side-sleeping, all-day office wear, and commuting, with several calling it their comfortable go-to grab-and-go earbud. That said, comfort isn't universal: some found stock tips caused pressure buildup or poor seal, requiring aftermarket tips like Tang Sancai or Spinfit, and one user returned them entirely due to fit and cable noise issues.

The cable and build quality are the most consistent weak points. Cable microphonics (noise from movement or touching clothes) are mentioned repeatedly as the main flaw, even at this price point, with one user routing the cable behind the ears to reduce it. A smaller number report durability problems, including a dead channel after limited use, weak connection points, and a cable stiffening over time, though others report their pair surviving roughly two years of rough treatment.
