Have another look at that internals picture (which is a render so take it with a grain of salt), they appear to be using an extremely unconventional arrangement of a rigid cone driven by two linear motors mounted at 45 degree angles to the driver axis. A rigid cone is challenging but a goal in many high-priced designs (less so for headphones but definitely in speaker drivers with say carbon fibre drivers).

Dual actuators mounted like that could be interesting for spatial audio and may also be used to overcome some of the challenges with suspending rigid driver cones.

In other words it should be interesting to see the reviews...
