In Japan thats a quite commong thing, i see people with DAP and even external amps quite often in Trains.
But yes, in most countries, that is not the case. But there are several reasons for this. Most people don't know that DAPs exist like at all. If you go to your local electronic store, they are not there.
In addition to that, people don't spend much money on music anyway and never did. People don't spend much money on earphone, why should they spend money on an DAP?
If you don't have good headphones/earphones, you don't need a DAP. You don't buy race slicks for an 60hp Volkswagen Polo that you use twice a week for shopping at Walmart.
Most people watch movies using streaming services, even though blurays look much better
Most people i know don't even set spotify to the highest quality because they either don't care about it and don't know this feature exists, or to save data.
So yes, most people don't care about quality. But thats their decision. I don't care if most people use TWS, ChiFi IEM, Japanese IEM or whatever.
Most people i know think that there is no big difference in quality anyway and that its all a scam. And when they test drive my gear and notice, its an insane big difference, they do the calculation and come to the conclusion, its not worth for them.
"Who spends 1000$ on an high qualty earphone that will last 10+ years? Are you insane? How am i supposed to afford my Chinese Smartphone that will maybe last 2 years if i am lucky for 1200+$ that has a lot of features i never use nor need, but i can use to show off to other people what i am able to afford."
If someone is looking at the image and thinks its fake
The bitrate of an FullHD BluRay is 50mbit/s
The bitrate of an 4K Netflix stream is 15mbit/s
The bitrate of an 4K BluRay is around 80-130mbit/s (Highly depending on Movie and Scene)
