Product Description

Introducing the Sennheiser IE 40 Pro black in-ear professional monitoring headphones that are ideal for musicians and DJs. Sennheiser have put all of their expertise from their previous successful headphones and produced the IE 40 Pro; small, light, almost invisible yet still powerful and precise. The in-built dynamic driver system helps to reduce listener fatigue so that the beautifully clear monitoring via the dynamic 10mm transducer can reveal all the detail of your audio without wearing you out.

The high expectations placed on in-ear monitoring are effortlessly satisfied by the IE 40 PRO thanks to an advanced dynamic driver system. The innovative diaphragm delivers a warm sound, yet powerful and precise, even in extremely loud environments. Even at maximum sound pressure levels, the signal remains distortion-free and precisely defined. The IE 40 PRO is a superior monitoring device for musicians and DJs that adapts to every ear. A compact design combines a secure fit with excellent wearing comfort. Its robust construction is designed to be suitable for the rigours of stage use from the connection to the cable duct.
