Sorta-kinda: I have an old launch iPhone that I've held onto so I can use it as an overbuilt iPod Touch. No apps, no phone service, it just works for playing music and does it well. I don't use it super frequently, but every so often I just wanna play some music offline without having to worry about anything else, and it does a great job.
If I went out more not in the car I'd probably get another proper MP3/DAC player. Back in the day I had a Sansa Clip I bought as an impulse Black Friday purchase and that thing was absolute fire. Small, great battery life, showed up in Windows as a standard external storage device, even had an FM tuner built in. Only downside was that it only had 2gigs of storage, but that just made me be a bit more choosy with what I put on it. If the damn thing hadn't wound up going through the wash on accident I might still be using it to this day.
