I use my audio jack in my car. The car has Bluetooth but only supports calls, no support for music.

Another point to make is that people here are saying wireless headphones are just as good as wired ones nowadays, but I don't think that applies to cheap ones.

Nowadays I very rarely use headphones with my phone out in public, so I don't see much purpose in spending money on a good pair for myself. I bought a cheap set of wireless ones awhile ago and they're terrible. They always struggle to connect to my phone and they have abysmal range, it struggles if my phone is sitting next to me rather than in my hands. I find any pair of cheap wired headphones you can get from any corner shop or supermarket is way cheaper and much more reliable than most cheap wireless ones.
