BT-3 Medium Earcone (Bag of 5)
The Telex BT series earcones work with any Telex Telethin driver that is connected to the Telex ET-4 eartube. They fit comfortably inside the ear canal and allow audio to pass through from the driver cleanly and clearly. If using the Telex ET-2 or Telex ET-3 eartubes, use the Telex EM series earmolds.
A medium earcone for use with ET-4. Comes in a bag of five.
