QCY Melobuds N20 BH25HT20A Wireless Bluetooth 6.0 Earphone -50dB Adaptive ANC 13mm Drivers Headsets 6 Mics HD Calls Earbud 40Hrs

With extended use, the earbuds maintain good sound quality and battery life. However, some users report that adaptive noise cancellation behaves more like static noise reduction in practice — it does not dynamically adjust to changing noise levels. The issue of earbuds falling out of the ear occurs sporadically and depends on individual ear shape. Voice announcements in English with a Chinese accent bother some users. Microphone quality is good, but in noisy environments people have difficulty hearing the caller.

Complaints mainly concern the passive nature of ANC — some buyers expected a greater difference between active and passive noise cancellation. A small portion of reviews mention connection issues with one earbud or wind noise in ANC mode. The matte finish on purple and blue variants is prone to scratching. Approximately 2.6% of reviews are critical, which is a low percentage, but the complaints are specific and repeatable.
