Sennheiser HD437 earcup adapter

SummaryI had an old pair of sennheiser HD437 laying around i didn't use cause the factory earpads were very thin, which made it unbearable to use for longer periods.Fortunately i had an extra pair of earcups from another SteelSeries headset, so i made this adapter plate.The passive open backed HD437 paired up with some good earcups results in rather amazingly good and very light wired headsetI dont know which other sennheiser headsets it would fit, but it should fit most "normal" sized earcups.Attached is both a slotted and unslotted version, the slotted version keeps the original open backed feature of the headset. The unslotted version is an attempt to make them more like a closed back headset to keep the sound leakage to a minimum.
