Overview

10 mm drivers and reliable, stage-ready design.

The Sennhieser IE 40 PRO in-ear monitor headphones feature an advanced dynamic driver system. The innovative diaphragm delivers a warm, powerful and precise sound. The IE 40 PRO excels 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 in-ear 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.

While most IEM systems use multi-driver solutions derived from hearing aids, the IE 40 PRO uses a next-generation dynamic single-driver design. As it turns out, the frequency range does not have to be split up into sections. Instead, it remains harmonious as a whole. It sounds well-rounded and its frequency spectrum has been considerably expanded. There is no distortion because the special resonates easily even at maximum sound levels. Phase problems and dissonances in the inner ear are therefore also precluded.

The Sennheiser IE 40 PRO delivers big sound, but is small enough to comfortably fit in your ear. Its advanced driver system produces a considerably expanded sound spectrum. Singers, musicians, sound engineers and DJs will appreciate their sound quality. The redesigned shape of the IE 40 PRO means each earbud sits flat, securely and feels weightless, even during long sessions.

Sennheiser knows that professional musicians are tough on their gear. That’s why it designed the IE 40 PRO in-ear headphone monitors with stage-compatible cabling. The IE 40 PRO features a cable with an innovative internal cable duct for reliability. So go ahead and do your thing on stage—let Sennheiser handle the rest.
