After endless frustration and annoyance at having to deal with tangled cords and accidental yanking on the cord (leading to dropped devices, damaged headphones, or earbuds ripped out of my ears), I bought a pair of Jaybirds a long, long time ago and have never looked back. I've not had any issues with Bluetooth connectivity, and what minor inconveniences there might be, or perceived loss of sound quality, is more than made up for by the freedom from having my ears tethered to my phone.
If you're complaining about Bluetooth headphones in 2016, it's because you've bought crappy ones. Those $40 Plantronics or no-name brand you bought off Amazon are shit. While we're at it, Beats are shit too. I will never buy any Beats product. Ever. Apple can plate every last Beats product in Rose Gold and stuff it where the sun doesn't shine.
But I also don't get the hate and cynicism they've gotten for removing the headphone jack. It's a remnant of the ancient past. Like a lot of technologies, people cling to it because it's familiar, unchanged, simple. And while those are good values to have, there are better reasons to leave it behind, like not having to deal with tangled cords, and not having your screen shatter into a billion pieces because a sudden movement of your arm caught the cord, yanked on the phone, and sent it flying through the air. If you're one of those audiophiles who needs wired headphones, why are you listening to lossy compressed music on your phone, anyway?
People fear change. People hate Apple not because they desire change, but because they have a long history of forcing that change despite the resistance of users, and that resentment is more about the way it feels forced upon them, the lack of being given a choice. But in the end, Apple is proven correct more often than not. That doesn't excuse their heavy-handed tactics, of course, but this whole conspiracy-mongering is just stupid. People concocted equally paranoid theories surrounding their decisions about USB, Blu-Ray, non-removable batteries, and floppy disks.
