Yes11Maker product pagebose.co.uk/p/headphones/bose-quietcomfort-ultra-headphones/QCUH-HEADPHONEARN.htmlRead 8 October 2026The exact original QuietComfort Ultra Headphones CustomTune FAQ states that a calibration tone plays at startup while the headphones are worn. The headset measures how the unique ear and ear-canal shape modifies the tone, then adjusts audio playback to that ear shape. This is a manufacturer-supported acoustic ear scan and device sound profile. It is separate from manual EQ, and does not claim a hearing-threshold test or a profile saved permanently across power cycles. The second-generation headphone is excluded.

Both music rows use Quiet Mode with full active noise cancellation, Bluetooth A2DP streaming at 75 dB SPL playback loudness, and all three equalizer bands at zero. Manufacturer testing used production-representative units in June 2023 with a variety of music tracks. The Bluetooth codec and Immersive Still/Motion setting are unspecified, so neither is inferred. These are manufacturer claims, not independent reviewer measurements.
