I don't know if I won the lottery, but I have sensitive hearing and I've never heard a coil whine from my XPS 13 (9300). The charging brick did develop a whine which I replaced. It also had the perfect keyboard with no wiggling key caps. Later production 9300 models and recent XPS laptops do have key caps that wiggle (once you notice, it's super annoying, I think I've been spoiled).
