The upshot is that I suffer zero vendor lockin. I bought Airpod equivalents from Aliexpress, the FIIL T1 Lite for $35. They are little marvels of Chinese engineering that do everything I need and actually sound great - they frequently outperform $100+ earbuds both in reviews on blogs and according to casual Reddit commentary. Since I only use them when out and about, it's not possible to experience any audio quality upgrade unless I sacrifice practicality and go with some closed-back over-the-ear cans.
