Huh, so that’s the term for that. I’ve not had many headphones that sealed extremely well since the last time I really got a proper closed-back pair was the Sennheiser HD428 maybe a decade ago. I knew absolutely nothing about good audio at the time so everything sounded pretty good to me and I just wanted an upgrade to $2 earbuds, haha. Either way, thanks! Agree that proper closed backs are generally going to sound worse than fully-or-semi-open alternatives, useful as the isolation will be in a lot of settings.
I’m familiar with his channel, surprisingly. Laughed at his tearing into the Grado GS2000, but to each their own I guess— I’m a sucker for wooden cups but agree that they’re a bit pricey for what you get. Thanks! Checked the video out, more bass isn’t really what I was in the market for.
