Just got these for a measly 25 dollars : r/headphones
The K240 MKII professional over-ear, semi-open headphones are a long-time standard in studios, in orchestras and on stages around the world. Its advanced Varimotion 30 mm XXL transducers deliver solid low end, accurate mids and crystal-clear highs. The semi-open design provides the airiness of open headphones with the powerful bass response of closed designs.
