Agreed, people spend a bazillion on headphones. I was absolutely shocked at my daughter's college at how many people have AirPods Max which cost $550. I just replaced the blue earpads on her Beats Studio 2 that I purchased on sale for her many years ago.
But I don't think that Massimo's companies are heavily invested in headphones except for B&W and their PX line. They're mostly stereo and home theater.
Stereo involves 2 speakers while Home Theater can involve 13 speakers (thanks to Atmos) and most people will aim for 7,9,11, or 13 to beat a soundbar's number of drivers. Very few people would choose a 5-channel system like the ones I have over, say, a Sonos soundbar which on paper is a 9.1.2 system
With a soundbar you just need to unpack, connect, power, run, and enjoy Atmos sound.
Try doing the same with a 13 speaker Atmos system. The boxes alone become an issue

Ideally, they'd all be wireless and run without a power plug

But even then you still have to mount them. I love surround sound but I would never build an Atmos system nowadays and I don't think I'm the only one here.
