SYB H.A.R.D. - Headset Anti-Radiation Device by Shield Your Body

Experience epic sound quality and added peace of mind by turning any standard headset into an EMF‑shielding powerhouse—no batteries required! 

Transform Any Headset into a Sound & Shield Powerhouse

Plug the SYB H.A.R.D. device inline with your 3.5 mm or USB‑C headset and it actively absorbs stray microwave radiation up to 20 GHz (including 5G) while filtering out audio interference—so you get clearer calls and deeper bass without compromise.

Crystal‑Clear Audio Boost

Unlike bulky air‑tube alternatives, H.A.R.D. uses a proprietary dielectric gel to neutralize EMF noise and actually improves your sound quality—no more hiss, buzz, or signal dropouts.

Universal Compatibility

Works seamlessly with any device or headset sporting a standard 3.5 mm or USB‑C audio jack—including virtually every phone, tablet, laptop, gaming system, and iPhone 15+ (note: not compatible with earlier iPhone versions). 

Lightweight & Hassle‑Free

Weighing in at just a few grams, H.A.R.D. adds zero bulk and requires no batteries—just clip it in, and you’re good to go. Clip‑on design keeps all your headset controls fully functional.
