I did an MBA a few years into my professional career, and I think overall it was a great deal. I was fortunate enough to have it paid for by my employer at the time. That particular program was geared toward working professionals, so the classroom time was just evenings and weekends. It checked the box for me being able to say I have a graduate degree on job applications, so I’d say it was worth it.
Yep! I have one that I use for music when I go running. It’s over 10 years old now, and still works fine. Phones are too heavy for that use case.
