I've been finding headphones that have unsually large drivers and I noticed that there isn't a thread for them. (Correct me if I'm wrong) So I thought it would be a good idea to make one.
I'll begin by throwing in the Lafayette Model F-990 with 3.5 Inch (88.9mm) drivers.
And the Koss KO/727B with 89mm drivers.
