Every product ships with its own measured frequency response - no marketing curves
11mm dynamic, 42dB adaptive ANC
An 11mm bio-cellulose driver with a dual-magnet motor, tuned to the Harman 2019 in-ear target with a ±2dB tolerance and a 3dB bass shelf you can switch off in the app. Hybrid feedforward and feedback cancellation attenuates up to 42dB at 100Hz, measured on a 45CA with the medium silicone tip.
LDAC and aptX Adaptive carry up to 990kbps, and game mode drops end-to-end latency to 30ms. Eight hours of playback with ANC engaged, 31 hours with the USB-C PD case, and a ten-minute charge returns two hours.
Free two-day shipping within the US on orders over $99, dispatched from Portland the same business day if ordered before 2pm PT. 45-day returns, five-year warranty, and spare parts published for every product we have ever shipped.

I mixed on a matched pair for eight months and checked the results against a mastering room I trust. The low end translated within a decibel. The DSP correction sweep took four minutes and fixed a 6dB null at 120Hz I had been compensating for by ear for two years.
I flagged a 0.4dB channel mismatch on my REF-1s - within spec, but it bothered me. The acoustics lead replied with the driver serial history attached and shipped a tighter-matched pair the next day. I have never had a support exchange like it.
Verified against my own i1Display Pro and the factory report held up across the full P3 sweep. My only complaint is that the local dimming blooms slightly on white text over black at 1,600 nits - switch the HDR profile to 600-nit reference and it disappears.
Three years on my Slate the battery was down to 79% health. Ordered the cell from Axiom at $48, downloaded the service manual, eleven screws and one connector. Back to full runtime for the price of a dinner. No other laptop I own would have let me do that.
