Why did you change pads? Replacement or better fit?
K371 didn't cost much more than the k361 and it came with extra sub bass boost so i got the k371. To be honest, if u wear glasses rather than contact lenses, the bass from the k371 probably drops to the 361 anyway
Yeah I agree with your opinion on expensive closed backs not worth it as much. But open backs leaves me "wanting more", more bass, more sound stage. Which is why I sold a pair of Sennheiser HD800 long ago to buy speakers instead. I like iems too, they're portable and usable in more situations. I have a Yanyin x HBB Mahina at $650, which if I'm being honest, think sound better running out of the Mojo2 than the K371.
But I really think the K371 at its price point hits a sweet spot for performance / form factor so I still think it's a good buy. I wouldn't want to buy more expensive headphones than this, where as I would for iems.
