Expert Opinion
Professional reviewers commend the MH40 for its first‑rate construction, high efficiency and portable yet robust design, noting that the removable lambskin ear pads provide comfort for extended studio use. However, they criticize the bass‑forward tuning that masks upper‑mid detail, the limited power handling that leads to distortion with high‑output amps, and the lack of active noise cancellation, which puts it behind competitors offering ANC.
What Users Say
Everyday users consistently praise the premium look, build quality and comfort of the lambskin pads, as well as the headphones' portability and ability to play loudly from phones. Recurring complaints focus on the ear pad size for large ears, the heavy bass emphasis, the absence of ANC and occasional distortion when driven hard.
Common Complaints
Ear pads not sealing for large‑ear users, bass‑heavy sound masking detail, distortion above ~100 mW power, lack of active noise cancellation, and medium‑high clamping force causing discomfort over long sessions.
