That controller had a 2600 mah battery for ~60 hours of operation. Much larger in power capacity and volume than what is suitable for tiny earbud like devices.

Ok so 260 mah for 6 hours? Using some 5 year not-that-fancy-at-the-time old technology (Ozmo2000)? That does far far far far more than send audio? That is much lower-latency than what we'd need to compete with Bluetooth (which radically increases wireless power needs)? For comparison, Google Buds are 120 mah & 5 hours. All we need is a 2x improvement in power, for a far less complex device, & we've had 5 years? You are making the case for me my man. This sounds more doable than I thought!! Miniaturization is indeed a challenge. Who does make really small wifi units? Who do they sell to? How much smaller do they need to be? I suspect it's simply never been a goal. And why would it be? There's no protocols that make wifi even potentially compatible with these sort of consumer device systems, no matter the size! Even with what we have today though, a wifi microphone or wifi gaming headset should be easily possible, no challenge at all, and could have far better quality & likely latency than what we expect from bluetooth. And I rather believe we could make smaller wifi if we had an interest in doing so. We are limited by our imaginations, our imaginations and our lack of standards/will.

  Not for specific applications like bluetooth headsets. There are application specific ICs that are made for the specific https://www.microchip.com/en-us/products/wireless-connectivity/bluetooth-low-energy/bluetooth-audio-and-voice-solutions# https://www.microchip.com/en-us/products/wireless-connectivi... Much like ASICS are a big step up in performanceand energy efficiency for crypto mining, they are in this application as well.
