64 Audio A2e

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
A great-fitting pair of custom in-ear monitors begins with a great pair of ear impressions, which are taken by a hearing professional called an audiologist. In the ordering process we will put you in touch with with your nearest UK audiologist to get the process started.

Custom Design Options
All 64 Audio custom IEMs are hand-built to order and fully customisable. Bespoke options include faceplate colour and artwork, cable length and colour, Apex modules, storage case customisation, and more - the choices are endless. 

Custom Monitor Ordering Process
It only takes a few steps to get your personal custom moulded in-ear monitors made. The estimated built time for custom moulds is around 3 weeks after the ear impressions are received by 64 Audio. Click the link to get the ordering process for getting your personal custom monitors started.
