I bought these for the M50x audio technica , and they work perfectly. They fit in really easily. The only thing I hate about it which isn't really a big deal if you buy a longer cable and I have the 4.9 ft one which isn't bad but I wish I got it a little more longer , cause if by accident you have the cable stuck in a weird way or if you pull it by accident it comes out. Overall pretty good if you watch out for the cable and don't accidentally pull it.
