Professional reviewers commend the RP-HT21 for its solid construction, comfortable ergonomics, and surprisingly punchy bass given its price, noting it delivers comparable sound quality to more expensive models. However, they criticize the lack of an inline volume control, the overly long cable, and the fact that the open-air design limits noise isolation, making it a solid budget choice but not a high-fidelity solution.
Everyday users appreciate the headphone's lightweight feel, comfortable fit, and strong bass for the price, often highlighting its value for casual listening and calls. Common complaints focus on the missing inline volume knob, the long cable length, and the perception that the sound is adequate for everyday use but falls short for audiophile expectations.



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.
