One pair of 40mm Peerless by Tymphany (HPD-40N16PET00-32) drivers for your head(amame) build.

Each driver is carefully mounted in its protective driver mount and has the leads pre-soldered to reduce the risk of damage when installing.

Pairs of driver are impedance-matched so the drivers have the same volume in both ears, something not guaranteed unless they're ordered in bulk and tested.
