Due to its innovative dynamic driver system, the IE 40 PRO will easily meet the high expectations for in-ear monitoring. Even in extremely loud environments, the revolutionary diaphragm provides a warm, but powerful and precise sound. The signal remains distortion-free and precisely defined, even at high sound pressure levels. The IE 40 PRO is a superior monitoring device that adapts to every ear of musicians and DJs. A compact design blends a comfortable fit with great comfort. The robust design has been designed for the rigorous use of the stage from the cable connection.

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.

Reinvented down to the last detail

Without monitoring sound, there is no performance. The IE 40 PRO is designed to provide the necessary reliability. To this end we have even reinvented stage-compatible cabling – the internal cable duct is a unique feature (patent pending). In short: the new system meets high expectations and withstands high stresses.

Small but mighty. Comfortable.

A big sound, but small enough to fit your ear: the advanced driver system brings a considerably expanded sound spectrum to the ears of musicians, sound engineers and DJs. The design, on the other hand, has been optimized, checked against hundreds of ear shapes, and redesigned. The result is flat, sits securely and does not ‘carry any weight,’ even during lengthy sessions.
