I'll take my music and podcasts over the sound of cars and building work thanks. Not everyone lives in a national park unfortunately.

Wires are absolutely an issue to many people. I understand audio quality is better with wires in general but when walking my dog the wires kept getting snagged on my coat, pulled out of my ears, and just prevented me fully rotating my head around and the experience absolutely killed any enjoyment of music for me. I think wired IEMS are absolutely better and if you have a desk job or have a situation where they don't bother you then they are the better investment, but if you want the convenience factor or any of the added bonuses like better a better mic or ANC then they are often worth it for those people.
