Sennheiser IE 40 Pro Monitor Earphones - Clear

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.

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.

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.
