Introducing the apexTM Technology.

When you seal a miniature speaker in an ear canal, the air inside becomes trapped. As the speaker produces sound it moves the air and causes the ear drum to work excessively. The pressure exerted on the ear drum causes ear fatigue, also known as listener fatigue.


By way of a pneumatically interactive vent the apexTM Technology (Air Pressure Exchange) relieves this pressure. With apex the sound is also dramatically improved across the spectrum, the soundstage is more expansive than ever before, and the technology is versatile allowing for a selection of isolation levels — all while minimizing ear fatigue.

Designed to work. All the time.

The pneumatically interactive vent is intelligently located to prevent debris build up and significantly minimize wind noise.

Apex Modules

Built for the most demanding users, the internal design of the module is mindfully made to be durable and virtually maintenance free.

Take control of your sound.

The apex modules provides levels of isolation at -20dB (apex m20) and -15dB (apex m15), while still relieving air pressure in a sealed ear canal. Now you can hear more of what you want to hear.

Easy to replace for different flavors.

The apex module is designed for ease of use when installing or replacing the module. If you own multiple modules you can easily rotate between levels of isolation and sound flavors.

Standard option.

The apex technology comes standard with all Custom-Fit A-Series and Universal-Fit U-Series earphones.
