9.2mm dynamic, 44-hour system battery
A 9.2mm dynamic driver with a PEEK and TPU composite diaphragm, tuned two decibels warmer than the AE-5 because most people use these on aircraft rather than at a desk. Adaptive cancellation reaches 38dB at 100Hz and reads cabin noise 400 times a second to hold it there.
Eleven hours per charge and 44 hours with the case, with ten minutes on USB-C returning three hours. Bluetooth 5.4 multipoint holds two devices at once, and the supplied USB-C dongle handles seatback entertainment systems that still only speak analogue or USB audio.
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.
