Wood Legit Series WLS-3 by Clear Tune Monitors

The WLS-3 has 3 balanced armature drivers which means high, mid and low frequencies work independently. This, in combination with a 3-way crossover, makes separating those frequency ranges nice and easy, and ensures that each instrument is defined impeccably. These custom molded in-ears are topped with our 100% wooden faceplate to look and sound amazing.
