U4-SE: Balanced Sound, Transparent Mids, Impactful Low End

The U4-SE is a Special Edition version of the popular 64 Audio U4 model and is for discerning listeners who crave detail and clarity but don’t want to sacrifice the presence of an impactful low end. In this model, 64 Audio placed the patent-pending apex module even closer to the speakers to relieve air pressure before it enters the ear canal. This makes for a wider sound signature, with a leaner bass that allows the mids to be more transparent and still provides incredible balance throughout all frequencies.

Apex Modules

In addition to the installed apex m20 modules, every U4 comes with an apex m15 module as an accessory. The apex modules are user-replaceable for different levels of isolation and sound flavors. The apex m20 module features -20 dB of isolation and the stock sound signature. Meanwhile, the apex m15 module offers -15 dB of isolation and leaner bass, with 4 dB cut at 20 Hz compared to the m20, making it the middle ground between bass attenuation and isolation.

What is apex™?

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.
