Stealth Sonics U2 IEM

Exciting new earphone maker Stealth Sonics brings striking design, convenience, technological innovation, and value at every price point. Combining a 10-millimeter dynamic driver and the highest-grade balanced-armature driver in each ear, the U2 in-ear monitors deliver a soft, blended sonic profile. Housed in an acoustically optimized composite material that’s soft and resilient, these IEMs cover a frequency range of 20 Hz to 20 kHz. The drivers are arranged in a finely tuned, crossover-free, time-aligned configuration, and the resulting sound signature is warm and musical with full bass, a smooth midrange and highs, and a well-textured sonic presentation. Each Stealth Sonics IEM comes stacked with proprietary technology to give you the edge in performance and comfort—all this at a total weight of just 4.17 grams per side. The U2 IEMs are so light, you can wear them for hours without feeling like they’re weighing you down.

By combing staff from its high-end audiology company, aerospace engineers, and consultants deeply entrenched in the world of touring musicians and engineers, Stealth Sonics has packed the U2 with proprietary technologies designed to provide high-end performance at safe levels. These technologies include Stealth Damping (which brings extended bass response for a deep, rich low end that you can feel), asymmetric diffused bores (which prevent standing waves that cause frequency resonances due to audio waves reflecting back and forth), and a one-way Klarity Valve (which relieves ear-fatiguing pressure and prevents your ears from hurting without affecting isolation). Finally, the advanced material makes for a hard yet extra-light shell with removable faceplates, so you can change the look for different occasions. Read more about the science behind the IEMs here.
