Device Shielding

Device shielding is a category with a lot of marketing noise and a small number of products with independent FCC-lab test data showing measurable RF reduction. We only stock the latter. Australia's RF limit is set by ARPANSA RPS S-1 at SAR 2.0 W/kg over 10 g.

Mechanisms with credible measured effect: shielded-flap wallet cases (during calls, with the flap between phone and head — DefenderShield publishes 99% RF block from 0–10 GHz (Signature) or 0–90 GHz (Ultra Armor) plus ELF magnetic shielding of 95.16% at 60 Hz and 98.25% at 300 Hz); Faraday pouches for full off-grid use (see phone and tablet pouches); laptop pads with a shielded base to reduce lap-side RF without affecting WiFi reception; and air-tube headphones (see air-tube range) which eliminate the wire-conducted path to the ear entirely. We don't stock EMF stickers, shungite plates, scalar pendants or back-only shields — none have credible independent test data, and back-only shields can actually trigger the phone's adaptive transmit-power boost, making exposure worse.
