The ATH-CKR7TW in-ear headphones deliver the exceptionally pure audio of Sound Reality in a true wireless design. The headphones feature specially designed 11 mm drivers with diamond-like carbon coated diaphragms and pure iron yokes to provide extremely accurate, high-fidelity audio. The headphones' housings contain dual-layer isolation structures that keep the electric circuitry separate from the acoustic space for optimal phase and transient response. Brass stabilizers reduce resonance and ensure linear diaphragm movement.
