“Long-term use of wireless earbuds may negatively affect brain function due to electromagnetic field exposure.”

No peer-reviewed study has demonstrated that wireless earbuds impair brain function. Bluetooth earbuds emit roughly 100–1,000 times less RF radiation than cell phones held to the head. The WHO, CDC, and Bluetooth-specific research consistently find no adverse neurological effects at these power levels. The claim's key supporting evidence comes from cell phone studies on children—a fundamentally different exposure scenario. While long-term earbud-specific research is limited, presenting speculative extrapolation as plausible risk is not supported by current science.

“Wireless earbuds communicate with each other by transmitting signals through the human brain.”

Wireless earbuds do not communicate by transmitting signals through the human brain. They use Bluetooth radio waves transmitted through the air, with one earbud typically relaying audio to the other. Even advanced technologies like Near-Field Magnetic Induction (NFMI) create a body-area network around the user — not through brain tissue. The only source making the "through the brain" claim is a low-credibility EMF-concern blog contradicted by every authoritative technical source reviewed.
