64 Audio is proud to introduce their four driver custom in-ear monitor, the A4s. This complete redesign of 64 Audio's four driver platform is elevated by the Dynamic low frequency driver, making this 64 Audio’s second hybrid custom IEM. Along with that major update, inside A4s is 64 Audio's Tia technology, LID and patented Apex and 3Dfit tech. While this is targeted at musicians looking for a rich enveloping monitoring experience, the frequency response, detail, and soundstage capabilities of A4s exceed other audiophile products at almost any price point.
