The 64 AUDIO A5 Custom IEMs are designed with a highly accurate "reference" sound signature. The A5 is considered to be the Little brother to the A10 and shares the same Quad High Frequency Driver set up. They're comprised of 5 masterfully tuned drivers per ear, which bring out detail and clarity in any genre of music. The A5 is tuned for neutral bass, incredibly accurate mids and a silky-smooth top end. The A5’s deliver a deep soundstage that will allow you to hear “hidden" parts of a recording that previously went unnoticed. Get ready to explore your music library all over again with the amazing precision and accuracy of the A5. This product is ideal for professional studio, acoustic performers, vocalists, and the most discerning audiophiles. The A5 features the innovative apex™ technology. Apex (air pressure exchange) is an enhanced version from the previous technology that relieves air pressure caused by miniature speakers in a sealed ear canal. Apex gives you a superior listening experience that simply cannot be achieved by traditional IEM’s.

Like all 64 AUDIO Custom IEMs, the A5 monitors are customizable and are hand built from your uniquely shaped ear impressions. They are inherently noise cancelling and are designed to work with a wide range of personal audio devices as well as all hard-wired and wireless monitors.
