A proprietary wide bandwidth moving armature design provides the listener with unsurpassed performance. Small size allows earphone to nestle well within the ear canal, maintaining an excellent air seal for improved bass and reduction of outside noise without causing discomfort.

"The GR8s give sensational clarity to vocals and present even the very highest register frequencies with precision and plenty of headroom. Per typical Grado fidelity, rock, pop, and soul tracks are rich with expressiveness and emotion and even classical tracks radiate through the frequency spectrum."
