    Custom in-ear monitors are made to order and custom crafted for every individual user making the ordering process different from standard earphones. It only takes a few steps to get your personal custom moulded in-ear monitors made. Click the link to learn more about the Ordering Process, or contact the Hifiheadphones support team.

    A2e is the first in the 64 Audio award-winning line of custom in-ear monitors. Packed with two drivers and the latest technology, the A2e provides high-quality sound with a low profile look and extremely comfortable feel. It's the ideal monitor for emerging artists, bands, and anyone seeking an affordable IEM that outperforms generic universal-fit earphones.

    New and improved for 2018, the two-driver A2e now features 64 Audio's exclusive LID (Linear Impedance Design) technology. Whether you’re plugged into your smartphone or performing onstage, LID enables a consistent sound that you can trust across multiple sources. Also new, the A2e features a refined sound signature, adding clarity and depth to the upper-frequency range.

    And as before, the A2e includes 64 Audio's innovative apex technology. Apex (Air Pressure Exchange) relieves air pressure caused by miniature speakers in a sealed ear canal, giving you a superior listening experience that simply cannot be achieved by traditional IEMs.

    Like all 64 Audio Custom IEMs, the A2e monitors are customizable and are hand-built from your uniquely shaped ear impressions. They are inherently noise isolating and are designed to work with a wide range of personal audio devices as well as all hard-wired and wireless monitor systems.

    Bespoke audio excellence.

    Custom Ear Impressions
