Portability is strong because the case is repeatedly described as pocketable, small, and easy to carry.

Preset EQ quality is mostly positive, especially Direct, Dynamic, and Treble+ modes, though SuperBass+ is too heavy for one reviewer.

Smudge resistance is weak because reviewers repeatedly describe the glossy earbuds as fingerprint-prone.

Setup and software simplicity are mixed: several reviewers call setup or the app easy, while others report slow pairing or calibration/connectivity friction.
