The Etymotic Evo delivers an honest pure sound and is perfect for music enthusiasts who want to hear every detail accurately. The sound character is authentic and transparent across the entire frequency spectrum paired with a tight, deep sub-bass and a wide soundstage. With this tuning, the Evo is suitable for all music genres and reproduces every sound truthfully and straightforwardly like a studio monitor. This sound constellation is achieved by three Balanced Armature drivers per side, configured in a two-way system with two bass drivers and a midrange-tweeter. The solid housing is injection molded in metal and specially shaped for good acoustics and a comfortable fit in the ear cup. The delicate, yet sturdy earphone cable from Danish manufacturer Linum has a 3.5 mm plug and is so light that you hardly notice it. The cable with the silver-coated strands supports the excellent detail resolution of the Evo earphones. Eight different pairs of ear tips are included for a comfortable fit, good sealing from outside noise, and optimal sound development. In addition, a round metal case is included for storing the Evo.
