64 AUDIO A4S
Four-driver hybrid audiophile in-ear monitor
64 Audio proudly presents their four-driver custom in-ear monitor, the A4s. At the heart of the complete redesign of this four-driver in-ear monitor is a low-frequency dynamic driver, making this 64 Audio's second hybrid Custom IEM. Along with this significant upgrade, the A4s features Tia technology, LID, as well as patented Apex and 3Dfit technologies. While targeting musicians seeking a detailed monitoring experience, the A4s' frequency response and sound profiling capabilities outperform most other audiophile in-ear monitors in almost every price range.
