Stealth Sonics U9 IEM Universal

Our flagship U9 or C9 is a nine driver hybrid designed in-ear monitor (IEM) system that features 8 balanced armatures and 1 high density 9mm neodymium magnetic dynamic driver. The 9 driver IEM has been painstakingly tuned and designed for extreme detail, precision and clarity. It was designed as the ultimate studio monitor IEM.

The 9 driver IEM was designed with inputs from renowned audio engineers and musicians around the world over many months. The result was our flagship IEM which features an extremely clear and flat-response IEM suitable for use in the studio or for artiste who demands ultra high precision monitors. The 9 driver IEM is our widest frequency range IEM (18Hz – 40 kHz) and was touted as one notable audiophile as saying, that it will allow the wearer to “…hear dolphns serenading canines on the beach.” The sound signature is supported by a deep bass response, beautifully transparent mid-range, crystal clear open highs that are powered by four super-high drivers. The 9 driver delivers an immersive soundstage to round out a truly superior listening experience.

This is housed in an acoustically-optimized composite material that uses Stealth Sonics Stealth Kompozit features that is not just very comfortable but light weight as well. Each side of the U9 weighs in at just 4.9grams.

The U9 also employs Stealth Sonics proprietary design features such as: the Klarity valve to reduce pressure build up and fatigue in the ear canal from long usage; Stealth damping for more controlled bass response ; and SonicFlo Acoustics for resonance and cancellation reduction.
