Someone drill holes into them and let me know how it sounds.

Had the opportunity to try them out from a coworker who bought them. The main difference with the open back is def a wayyy smaller sound stage. Would only get these if you want to use it around other people like the office and even still there’s probably better closed back headphones out there. Not too bad for like 150 but would def go with the original vs the closed back for full price.
