RF Blocking Headphone Covers

PROVEN EMF REDUCTION Backed by independent testing from RF Exposure Lab (a recognized leader in FCC SAR standards), our patent-pending physical shielding demonstrates an average 98.1% reduction in real-world RF exposure at standard Bluetooth frequencies. Across various headset models, rigorous internal testing confirms a consistent, measurable reduction ranging from 90% to over 98% based on make and model. TARGETED PROTECTION (WHY STICKERS DON'T WORK) Many companies sell "EMF stickers" or pendants claiming 99% shielding. However, they only apply a tiny amount of material in the wrong spot, offering zero measurable protection to your body. To truly protect yourself, the shielding material must sit directly between the source and your body. RadiArmor's "smart shielding" positions our breathable RF-blocking fabric exactly where you need it—creating a definitive barrier that reduces direct exposure from 90% to over 98% while allowing outward signals to function normally. MAINTAIN SOUND & SIGNAL Because our shielding is targeted to the side resting against your head, the rest of the earpad remains uncovered. This preserves your Bluetooth signal strength and crystal-clear sound quality for uninterrupted calls and music. TWO SIZES FOR A PERFECT FIT We offer two sizes to cover most on-ear headsets and over-the-ear headphones. Please measure your earpad diameter to ensure the best fit: MEDIUM: Ideal for most on-ear office headsets (Jabra Evolve, Poly Voyager, Logitech Zone) with earpads 5.5–8 cm (2.2–3.1"). LARGE: Best for typical over-the-ear headphones (Sony WH-1000XM, Anker Soundcore, Bose QuietComfort) with earpads 8–11 cm (3.1–4.3").
