Sennheiser SC165 Binaural USB-C Headset Headphones (508356) In good used condition, only used a few times, this USB C headset does not work properly on Android phones, (android seems to treat it as standard headphones, the microphones would not work.) It works perfectly on computers, laptops. The USB C cable is detachable from the volume control, may be able to used standard 3 mm audio jack (but I have not tried.)
