Etymotic has been building in-ear headphones since 1984 and has plenty of experience in the field of acoustics and hearing aids. And for more than 20 years, the Illinois, USA-based manufacturer has been active in the field of in-ear monitoring (IEM) and during that time, they have consistently pushed the use of balanced-armature drivers. In fact, the classic ER-4 is considered a pioneer in this field. Now, for the new Evo model, Etymotic has fundamentally revised the design in many respects. The result is the first Etymotic IEM with multiple drivers.

The PurePlay Z7 uses a hybrid driver configuration. For the first time, Lypertek is using one titanium-coated dynamic driver and two balance-armature drivers on each side; these work together in tuned frequency ranges in a correspondingly tuned housing and are thus supposed to ensure particularly good detail resolution.
