The in-ear monitoring sound of the Sennheiser IE 400 PRO delivers a noticeable punch, clear high frequencies and transparent mid-range reproduction. Even at a high sound pressure levels, the IE 400 PRO's warm sound is free from artifacts and distortion. With the developed TrueResponse technology, the dynamic driver measuring a mere 7mm generates tremendous resolution and prevents acoustic stress, even during long periods of use. Distortion, overlapping frequencies and feedback peaks which otherwise occur frequently are no longer a problem.
