Well, here is the tradeoff they made:
Low latency and high bandwidth both cost power. You can use a cheaper, low-power radio and the battery will last longer and improve rated battery life.
-OR- you can use higher power radios, which shortens battery life. Then you need to compensate with a bigger battery, and therefore a heavier headset. Are you familiar with the Audeze Suspension Strap(TM)?
That said, a $300 phone can make a round trip ping of 6ms over wifi (on a 2.4GHz band), transfer 200 Mbps, play audio, power a 1440p touch screen, stay connected to wifi around the house, and have a 10+ hour battery life. The amp for planar drivers is obviously a power hog, but there's some room for improvement on the electronics side, which Audeze may become more well versed in for their next line of headsets. This whole segment is new to them, so you have to cut them some slack and report the shortcomings for them to improve.
I'm willing to assume that planar drivers are expensive to manufacture, otherwise this headset is being thrown together with some cheap electronics and a huge markup.
