64Audio A4S Custom IEM Earphone

64 Audio is proud to introduce our newest four driver custom in-ear monitor, A4s. This complete redesign of our 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 our Tia technology, LID and our 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.
