So I can use my pair of headphones for everything. They work in my phone, my DJ mixer, my computer, and the broadcast board at the radio station. They never have technical malfunctions, there is no interference, and never run out of power.

It’s another things to charge and keep track of. Have a long flight and forgot to charge your phones? Too bad.

The four biggest advantages for a wired headphone when compared to Bluetooth are

1. Headphones are cheaper
2. No lag to receive audio
3. Headphones don't need to be charged
4. Easier to connect/disconnect.

This doesn't even touch the preference stuff, like some people prefer having a wire to avoid losing headphones, and others like wireless. Or quality, which is a can of worms I don't want to even touch.

Bluetooth is compressed garbage
