I have $4,000 audio setup (Sennheiser HDV820 + Sennheiser HD800) and honestly a $500 Sennheiser HD650 plugged directly to a 3.5mm adapter sounds way more fun in everyday use. The exponential quality curve only goes up to certain point and beyond that it's all about the sound characteristic (HD800/S is good for classical/jazz) and how much the manufacturer is going charge for it. That being said, I still use AirPods Pro a lot more than both HD800 and HD650 due to convenience of using it even though the sound quality is way worse. Fidelity isn't really much of a concern when I'm doing something else with background music. I'm very excited about AirPods Max.
