Have to be honest. I do a bit of music producing, so I am a little bit of a snob about quality.
But on a phone, on the go, the convenience of bluetooth and not having to be tethered to anything beats the obvious downsides for me.
I use proper equipment when I want to listen in high quality and properly.
So, I haven’t had a jack input in a long time, and have missed it exactly zero times so far. But can really well understand the need for it if phone’s often with you on the go and you don’t often sit down in a specific listening spot at home. And probably any other reasons are equally understandable. I think I am the weird one here.
