Products in the top-left offer the best value (high score, low price).

Professional reviewers praise the A71 for its surprisingly wide soundstage, solid isolation and strong bass-vocal balance, especially given its low price. However, they criticize the plasticky construction, inconsistent spec listings and potential durability concerns, noting it feels less robust than benchmark models like the ATH-M50x.
Everyday users love the comfort of the rotatable pads, the effective isolation and the convenience of the foldable design, but many complain about early-life failures such as speaker breakage and the overall heavy, plasticky feel of the headphones.

“Incredibly comfortable with sturdy, rotatable pads that survive rough handling; good for extended wear”



Professional reviewers praise the M20x for its tight channel matching, low distortion, solid build, and strong bass response, noting excellent value for the price. However, they point out comfort issues after extended wear, a predominantly plastic construction, a fixed non-detachable cable, and occasional high-frequency inconsistencies.
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.
