BA diameter and composite diaphragm ingredients are not published. Acoustic crossover roles are not inferred.","anc_type":"QuietSmart 3.0 adaptive hybrid ANC. The maker Japanese technical release separately confirms feed-forward and feed-back architecture. The six-microphone array is not treated as six dedicated ANC microphones.","anc_adaptive":"Current global page says real-time adaptation every 0.3 seconds. The JP release says over 400 detections per second for another internal process. Neither figure is stored as an interchangeable universal refresh rate.","anc_claimed_attenuation_db":"Up to 50 dB maker maximum claim, not reviewer-measured overall attenuation.

The JP technical release explicitly states three per earbud.","microphone_count_total":"Six physical microphones in both buds. ANC-specific count and shared roles are not separately established.","bluetooth_codecs":"Global spec names aptX Lossless, aptX Adaptive, LDAC and LC3.
