The Galaxy Note 10 has no headphone jack. Samsung was one of the last holdouts who still included the 3.5mm jack people are still using on their phones. Now the Note 10 doesn't even come with an adapter.
The point is, 267 million people still use the 3.5 MM jack. 30% of Samsung users don't use Bluetooth headphones, which means 267 million people still use the jack. The point is, people still use the jack.
Well 267 million people will have to stay with their old devices since all current phones moving forward will kill the headphone Jack. This isn't something new. Everyone is doing it
The no headphone jack is a meme at this point lol most people don't care about it. Plus if you care about audio anyway buying a USB-c DAC/amp is going to provide a higher quality experience than a built in plug anyways.
