64 Audio is proud to present its unique four-driver earphone, the A4s. The complete redesign of the four-driver in-ear monitor features a low frequency dynamic driver at its heart, making this 64 Audio's second hybrid Custom IEM. Along with this major upgrade, the A4s also features Tia technology, LID, and patented Apex and 3Dfit technology. While this is aimed at musicians looking for a detailed monitoring experience, the A4s' frequency response and sonic capabilities are superior to other audiophile earphones in almost every price range.
