Key Features and Benefits: Dynamic drivers of the next generationWhereas most in-ear systems use multi-driver solutions derived from hearing aids, the IE 100 PRO uses a next-generation single dynamic driver. As it turns out, the frequency range does not have to be split up into sections, thus 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. Small but mighty, and comfortable tooWith mighty sound, but small enough to fit your ear, this 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.
