This headband cushion is designed as a replacement for Audio-technica ATH AD300 headphones. The single piece replaces the two original cushions and is a practical solution if the existing headband cushions are damaged or worn. The cushion provides a stable and firm fit, which can help distribute pressure evenly over the head when using your headphones. While this replacement removes the headphones' original ability to tilt back and forth, the side-to-side movement is maintained, ensuring a basic degree of adjustability for your headset.
