As seen on CNN - Use a "Hollow Tube" Earpiece. In 1995, our parent company responded to the claim that cellphones were harmful by inventing the worlds first Radiation Free Antenna for cellular phones. Raising over 20M, the company emerged as RangeStar and launched the Worlds first innovative antenna manufacturing and R&D company with nine antiquate testing chambers and manufacturing partners in USA, China, and Taiwan.
The RF3 is the "Original" and Patented solution that effectively eliminates the effects of harmful radiation during use. We tested this on "RICK" our dummy head during our SAR "Standard Absorption Rate" tests and we effectively measured ZERO.
No kidding, the reviews are AWESOME when it comes to sound quality. We rate this product in our TOP FIVE for customer satisfaction.
