Why isn't that good enough?
Why isn't people liking something they were swindled into paying way too much money for not good enough? Do you really have to ask that? Maybe you can ask the anti-trust regulators why they feel the need to protect people from themselves?
It's absolutely about the average consumer
It's absolutely not. It's not about what the consumer wants at all. These companies didn't remove them because customers wanted them removed. They removed so that they couldn't use them anymore.
And how does that help the competing manufacturers who also removed their 3.5 jack?
Because they also made buckets of money removing them. Every fucking one of them removed the jack and then immediately introduced new Bluetooth headphones that were several hundred dollars. Even Fairphone went down this hole.
No one makes money selling $7 wired headphones.
Are you beginning to understand how things you don't buy still affect you yet?
