First IEM designed in collaboration with world class drummer Aaron Spears

AS-7's Sound Design

We proudly present the AS-7, our first signature IEM. Aaron Spears (Drummer Usher/Ariana Grande), has shared his vision with us, resulting in a revolutionary new design, that makes these universal fit earpieces capable of accurately reproducing even the smallest detail in sound.
With 7-drivers picking up and faithfully reproducing the whole frequency spectrum, the AS-7 offers a more personal listening experience by letting you tailor its original sound with two interchangeable filters of different impedance (150ohm & 300ohm).
These professional level In-Ear Monitors feature our exclusive WISE technology and will enhance your performance by letting you experience incredible depth and detail in your sound like no other. With AS-7 you’ll never miss a single detail!
Also available in Custom Fit.
