Professional reviewers praise the Monitor series for its high sensitivity, easy drivability from low-power sources, and the practical 90° swiveling ear cups that aid single-ear DJ monitoring. The Hi-Res certification and extended 20-40 kHz frequency range are highlighted as strengths, while the slight treble boost and plastic-heavy build are noted as drawbacks.
Everyday users appreciate the strong bass, clear vocals, comfortable protein cushions and versatile cable options, considering the headphones a great value for the price. Common complaints revolve around a lightweight plastic chassis, occasional cable detachment, treble harshness on bright music, and confusion over the listed maximum input power.

“The Monitor 60 delivers pretty good frequency response that matches direct recordings, with vibrant bass without excess but a slight 4‑5 kHz bump.”

“Comfortable protein cushions let me wear them for hours without ear fatigue.”




Professional reviewers praise the M20x for its tight channel matching, low distortion, solid build, and strong bass response, noting excellent value for the price.

Everyday users commend the headphones for strong bass, effective isolation, lightweight comfort in short sessions, and clear sound without needing an amp, while repeatedly citing ear fatigue after 1-2 hours, the non-removable cable, a plasticky feel, and minor high-frequency quirks as common drawbacks.
