An implementation or variation on this theme is surely the future of in-room audio:

The math says, if implemented correctly, WFS is better than sitting in the sweetspot of any speakers. Also, there's no sweet spot with this technology.

Design for repair isn't trivial.

It would force compromise on every other aspect of the product.

In the real world = more time (at every stage of the R&D and manufacturing process) + extra material costs (more tooling, more PCBA's, more screws, etc.).

I personally think that this issue will become a very big deal over the next decade or so, but at this point the market isn't applying enough pressure for the big companies to change their GtM processes.

You can get a decent set for about a hundred bucks.

I work in this area.

There's a huge runway in front of us for both products and technology.

'Acoustic Holography' has worked for some time, commercial implementations have been few and far between, mostly because what's in the market is already selling boatloads without it.

It'll come eventually, there are a few groups dedicated to it.

A successful anchor in that space will allow companies to go deeper into applications.

Acoustic room splitting, Silence on demand, etc.

Try IEM's.

In general, anything heavy related to headphones = bad.

You can get the equivalent of state of the art ANC performance with a pair of passive IEM's that fit properly.

Try using memory foam tips if you have trouble with tips fitting your ear shape.
