Open (with no insulation) or closed (passive noise insulation) or semi-open (intermediate version). Open headphones sound more airy and provide a wide stage, closed ones provide noise isolation and amplify low frequencies.
Most of the headphones are dynamic but there are electrostatic, isodynamic, etc.
A cable for a balanced (symmetrical) connection allows you to neutralize the negative impact of cable length on signal transmission, and also has a beneficial effect on the final sound.
