The 64 Audio A2e is the most affordable Custom IEM with apex technology. The A2e packs two drivers in a single package for a low profile look and an extremely comfortable feel. This product is perfect for emerging artists or bands, houses of worship, and anyone looking to purchase a high-value Custom IEM at a reasonable price. The A2e 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.

The A2e monitors 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.

Proprietary Technologies

Apex 3DFit


A passive crossover network that directs frequencies to drivers that are optimized for their reproduction.
By removing pneumatic pressure from the ear canal, sound is felt to be more spacious and outside the head when compared to traditional earphones.
A superior balanced armature driver design that pushes the diaphragms in the center. This yields a deeper, more dynamic bass response.
The capability of the earphones to reduce ambient or stage noise when properly inserted.
The configuration and arrangement of drivers per frequency band.
The range of frequencies that the earphone is able to produce under typical use.
The load or resistance that the earphone will present to an amplifier. Lower resistance is much easier to drive than high resistance.
The Sound Pressure Level (SPL) produced per 1mW of input power. The higher the sensitivity the less power is required to drive the earphones.
Sound bores are used to channel the sound from a driver or a group of drivers to the eardrum. Multi-bore designs allow unique frequency shaping capabilities.
ApexTM restores proper phase response at the eardrum by switching from pressure-based amplitude to velocity- based amplitude.
A revolutionary technology that eliminates pneumatic pressure that causes excessive eardrum movement.
