During a training event; my student was learning to judge height above the runway; and the landing went long due to our duration in ground effect. We were asked by Tower to expedite our taxi down the runway and clear [the runway].  During the turn; my foot became entangled in my headset cord. In an effort to manage the aircraft; I pulled my headset plugs from the ports and dislodged my headset on my head. It is a very confined area and the ports are under the center portion of the instrument panel. I made every effort to stop the aircraft prior to the hold short intersection and crossed the hold short line that guards the runway. Factors that affected my performance include a small cockpit environment leading to cord entanglement. Small area that does not favor any ability to clear a runway; and stop the aircraft if the pilot finds them self in any kind of predicament. Faded hold short markings on taxiway. Plan of action is to review this scenario with local instructors. Incorporate this situation into 'real world' training for my students. Renewed priority for 'hotspot' training.
C152 instructor pilot reported their feet became entangled in their headset cord while taxiing and they could not stop the aircraft at the hold short line they were supposed to hold short of.
