KINETIC BASS – You can feel it!
Kinetic Bass is a revolutionary hybrid conduction technology that elevates the In-Ear Monitor sound experience to unprecedented heights. Kinetic Bass isn’t just about hearing bass; it’s about feeling it, connecting with your music on a profound level.
Traditional in-ear monitors often fall short in providing depth and sensation because they only deliver half of the sound equation. In a natural open-ear setting, you perceive sound through two avenues: air conduction and bone conduction. Air conduction involves hearing with your eardrums, while bone conduction transmits sound through the bones in your head to the inner ear (cochlea). Hybrid conduction integrates both air and bone conduction, providing a comprehensive sonic experience.
With Kinetic Bass technology, a specially designed 10mm dynamic driver is strategically positioned, open and ported, directly facing the exterior of the IEM shell. This configuration allows low-frequency sounds to be directly channeled to the ear cartilage and the surrounding area. These low frequencies are then converted into kinetic energy, reaching the inner ear through bone conduction. The result is an immersive sound quality with bass that you not only hear but can also feel—a heightened dimensionality with an unparalleled low-frequency extension that takes your audio experience off the charts.
Simply release the pressure – ATOM Venting
Introducing the Air Transferring Open Module (ATOM), a groundbreaking pressure relief system designed to alleviate the buildup of pressure in a sealed ear canal, thereby significantly reducing listener fatigue and enabling extended, comfortable listening sessions.
Say goodbye to pressure discomfort and embrace easy listening.
In traditional in-ear monitors, the ear canal is hermetically sealed. As the diaphragm of the miniature speakers (driver) moves to generate sound, it creates air pressure with no outlet, directly impacting the ear drum. This pressure triggers the ear’s acoustic reflex, causing the ear drum to tighten in defense against loud sounds, leading to listener fatigue. Prolonged exposure to this reflex may contribute to long-term hearing loss.
Experience safer and prolonged listening sessions.
The ATOM venting system prevents the triggering of the acoustic reflex by allowing the built-up air pressure to escape. This enables your ear drums to remain in their natural, relaxed position, facilitating longer and safer music enjoyment without ear fatigue. The result is a broader soundstage that feels more natural, akin to an open-ear listening experience, while retaining all the advantages of in-ear monitors.
Tailor your listening experience with interchangeable options.
ATOM technology offers four distinct options, each providing varying levels of isolation and bass. The Frontier Series Universal-Fit models feature the effortlessly swappable and super ergonomic ATOM XS modules. For Custom-Fit models, you can choose between internal ATOM or ATOM X modules, both of which are interchangeable, allowing you to customize your listening experience to suit different preferences and musical genres.
OPEN ACOUSTICS System
Introducing the Open Acoustics System, a paradigm shift in in-ear monitor technology designed to deliver an expansive and natural listening experience by eliminating traditional sound tubes. This innovative system comprises three key components: Open Drivers, Sound Reactor, and Sound Reflector.
Our Open Drivers represent a departure from conventional designs by forgoing sound tubes. Instead, they radiate sound directly into the Sound Reactor, allowing the audio to flow freely to the ear canal. This revolutionary approach results in a significantly larger soundstage and a more pure, natural, and open listening experience, unencumbered by the resonances introduced by traditional tubes.
The Sound Reactor acts as a chamber that shapes the sound emitted directly from the open drivers. Unlike many traditional in-ear monitors that use dampers and filters, the Sound Reactor harnesses natural acoustics to sculpt the audio profile. This approach ensures a nuanced and unadulterated sonic output, contributing to the overall purity and authenticity of the listening experience.
Situated in the canal stem, our open high driver features a distinctive Sound Reflector. This component is designed to direct high frequencies precisely into the ear canal. The outcome is a remarkable rendition of smooth and airy highs with exceptional extension. By incorporating the Sound Reflector, we achieve a level of audio clarity that surpasses the closed-in and stuffy sound often associated with traditional IEMs.
The Open Acoustics System redefines in-ear monitor technology, offering a refreshing alternative to the constraints imposed by sound tubes. Experience a vast soundstage, natural acoustics, and unparalleled clarity with our innovative approach to audio design.
