01
Adaptive cancellation
Six microphones — four outside, two inside the cup — sample the environment and the residual sound at the ear. The processor inverts the difference rather than applying one fixed curve. The practical result is that a door closing is reduced as quickly as an engine drone.
02
Room-aware tuning
Three profiles (kitchen, carriage, studio) apply small, published adjustments rather than a mystery "enhance" switch. The studio profile is flat; the other two lift low frequencies slightly to compensate for masking noise.
03
Spatial engine
Head-tracked spatial audio using impulse responses recorded in three real rooms. Tracking runs from a six-axis sensor and updates at 200 Hz, which keeps a voice anchored when you turn your head.
04
Materials and repair
Recycled aluminium yokes, lambskin pads and a bio-based polymer shell. Pads, headband cover and battery are replaceable; the fasteners are standard Torx, not glue.
