This uses oxygen-free wireless transmit technology - the Max's 0s and 1s are higher fidelity bits than what you get with other headphones. It is powered by Apple's new F-U chip.
That is why the pairing is proprietary - it is not easy to find an oxygen free wireless path. It also operates at in the GHz band - that *billions* of wireless transmits per second.
Can't wait to get mine - hope it works with the F-Me-2 chip in my Apple Hermes watch. Magical!
