The page carries generic Immersive Audio app text that does not fit the original QC manual. No Immersive Audio or CustomTune claims are stored. The page has conflicting quick charge claims: the FAQ says 15 min for 4 h and the original QC comparison says 15 min for 2.5 h. The FAQ pair is stored from the separate first-generation page. The published 0.520 lb is stored as the converted maker claim of 235.9 g. The secondary 240 g table does not override the maker. No shell or headband materials are assigned from the generic Metal/Plastic/Leather product-material list. The adaptive call microphone wording does not identify DSP versus AI processing, so microphone_noise_reduction is omitted.
