* Apply a light pressure on the chest piece to listen to low frequencies and a firmer touch when monitoring a child's higher one. * Two twin thick wall tubes provide exceptional individual sound transmission from chestpiece to each ear. * Shaped ear tips for comfortable and acoustically sealed monitoring.
