    • The Sony MDR-4L1 is a very collectable lightweight on ear Dynamic Stereo Headphone model.
    Originally released by Sony in 1981, they are most famous for being the stock headphones bundled with some of the earliest portable cassette players, such as the 1981 version of the very first Sony Walkman, the TPS-L2 (later renamed the WM-3) and the Sony Walkman WM-3 "Deluxe" edition.
    It was only made for a couple of years and then superseded by the MDR-4L1S.
