Stealth Sonics U4 Universal Quad Driver In-Ear Monitor

Installment option available at check out page

 The four-driver U4 in-ear monitor features a balanced armature design favored by anyone seeking the flattest response possible. Housed in acoustically-optimized composite material that is soft and resilient, the Stealth Sonics U4 IEM offers advanced detail and crisp transients and covers a frequency range of 18 Hz to 23 kHz. The sound signature is supported by a punchy bass, a silky midrange and crystal-clear highs for a fully balanced listening experience.

  • Most people don’t know that your ear is a unique acoustic machine, with a frequency response all its own. And like fingerprints, every ear is different. That’s why we offer IEMs in both convenient, affordable universal-fit models or custom-tuned systems offering the ultimate in personalization. Choose from three multi-driver configurations, including balanced-armature and hybrid-driver options.

    Our Precision-Tuned In-Ear Monitoring Systems use our proprietary SonicFlo technology to engineer second-bend impressions that conform exactly to your inner ear canal, for superior fidelity, minimal acoustic interference and a perfect fit.

    Our universal in-ear monitors offer convenience, customization and value at every price point. All universal IEMs feature Stealth Damping Technology with removable faceplates for extending bass response, and a variety of cable options to further fine-tune your experience.

    All of our custom and universal in-ear monitor systems are built using our Iso-Stealth technology adapted from our aerospace technology innovations, for optimum isolation, anywhere.
