I do. Right now I’m listening to music on my phone through wired headphones. I have too many smart things already connected via bluetooth to my phone: 2 different wireless speakers, an electronic drumset, smart TV, car, fitness tracker (I’m sure I’m forgetting something) and I came to like the idea of physically plugging something in order for sound to be played through it, especially if both phone and external device are physically close to me during the whole interaction, like with a headset.
