Jack Adaptor screwable (M5 thread) 3,5mm to 6,3mm for DT 770 PRO and DT 990 PRO models
The DT 770 PRO and DT 990 PRO models have been converted from the M8 thread to a smaller M5 thread so that the headphones can be connected to a mobile device with a protection cover using the 3.5 mm jack (with unscrewed jack adapter).
