The Advantages of ACS LiveSound for Musicians
● LiveSound filter + breathable resonance chamber = professional-grade sound
With meticulous tuning, VIORA achieves a flat frequency response that faithfully presents every detail in your music.
● Stay connected without removing your earphones
On stage or in the studio, when the music pauses, you don’t need to take off your earphones to hear your bandmates or audience. ACS LiveSound keeps you connected to your surroundings, so you never miss a beat.
● Restore the feeling of playing live as a band
Conventional IEMs isolate you from ambient sound—while they help you hear your own mix, they often disconnect you from your bandmates. ACS LiveSound blends in just enough stage sound so you stay musically connected to the ensemble.
● Protect your hearing without sacrificing stage awareness
Some performers wear only one IEM to hear ambient sounds, leaving one ear unprotected. ACS LiveSound allows you to safely blend in ambient sound while protecting both ears, balancing immersion with safety.
● Preserve bass response, even with open filters
Poorly sealed IEMs often result in major bass loss. ACS LiveSound maintains frequency integrity, letting you hear ambient sound at -17dB attenuation without sacrificing low-end performance—ideal for live performance monitoring.
● Reduce physical wear and extend earphone life
Frequent removal and reinsertion of earphones can wear out cables and connectors. With ACS LiveSound, just lower the volume or unplug your source—you can still hear your surroundings without removing your earphones.
● Avoid occlusion effect—hear your voice naturally
Fully sealed IEMs often create a booming “in-your-head” sound when you speak or sing. LiveSound's two-way venting releases pressure, eliminating occlusion and allowing your voice to sound natural.
● Relieve eardrum pressure for longer comfort
Traditional sealed IEMs can build up inner-ear pressure, causing fatigue during long sessions. LiveSound technology relieves this pressure, reducing fatigue and allowing longer, more comfortable use during rehearsals or gigs.
Universal Fit with Custom-Like Comfort
When we set out to design our new universal monitoring earphones, our goal was more than just perfect sound—we wanted everyone to truly hear it.
With over 20 years of experience in crafting custom in-ear monitors, ACS applied that knowledge to develop a universal fit that conforms to a wide range of ear shapes and sizes—ensuring comfort, secure fit, and precise sound delivery.
Dual-Fit Transform: One Earphone, Two Professional Modes
With ACS’s proprietary JANUS Dual-Fit system, VIORA can transform in just 10 seconds—from a lightweight, convenient universal mode with studio-grade isolation, to a full custom-fit mode offering maximum seal and isolation for high-pressure stage environments. Go here to find out more about
