These are good studio monitoring headphones and flat sounding as it should be for that purpose.
Mixed reviews on general use.
Also this could be a price error because there's another item for $319 https://www.mightyape.co.nz/mn/buy/mighty-ape-audio-technica…
Bunch of other good deals on Audio Technica and other brands too: https://www.mightyape.co.nz/mn/c/audiophile-sale/
I have a special edition of these that are like a decade old and the right driver died.
Timely offer
