Sennheiser IE 40 PRO

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. It’s robust construction is designed to be suitable for the rigors of stage use from the connection to the cable duct.

The IE 40 PRO improves the way you perform by enhancing the way you hear.

Dynamic drivers of the next generation

Whereas most IEM systems use multi-driver solutions derived from hearing aids, the IE 40 PRO uses a next-generation dynamic single-driver. As it turns out, the frequency range does not have to be split up into sections but remains harmonious as a whole. It sounds “well-rounded”, and its frequency spectrum has been considerably expanded. There are no distortions because the special diaphragm – unlike the more rigid drive principle of the multi-way drivers – resonates easily even at maximum sound levels. Phase problems and dissonances in the inner ear are therefore also precluded. The difference is audible, even noticeable in the entry-level model.
