What Defender Shield does
DefenderShield is a privately held US consumer electronics company headquartered in St. Petersburg, Florida, that designs and sells EMF (electromagnetic field) radiation protection products directly to end consumers. Founded by former telecommunications engineer and executive Daniel T. DeBaun, the company has operated for 15+ years and reports more than 300,000 customers served worldwide. Its catalog of 50+ SKUs spans phone cases, air tube headphones, laptop and tablet shields, Faraday bags, wearable shielding (blankets, jackets, beanies, gloves, shorts, scarves, pregnancy belly bands, sleep masks), blue light glasses and supplements, RFID-blocking accessories, and educational books. The company's technical differentiator is its proprietary Ultra Armor+® and Ultra Armor® multi-layer metallic composite shielding, tested to block up to 99% of EMF radiation across the full 0–110 GHz range including all 5G bands and ELF battery emissions, validated by FCC-accredited independent military lab testing. Its air tube headphone line, which routes sound through hollow tubes to eliminate RF exposure at the ear, is covered by Patent License #6453044. DefenderShield makes money through one-time hardware purchases via its own DTC e-commerce storefront at defendershield.com, with prices ranging from $4.49 accessories to $719.99 wearables, HSA/FSA eligibility in the United States, free domestic shipping over $150, and global fulfillment via FedEx with duties paid at checkout. Marketing relies on content-led education, earned media coverage in major outlets, and influencer/advocate endorsements targeted at health-conscious consumers, parents, pregnant women, biohackers, and travelers.
