How does it work?Updated a year ago

Ethos is embedded with custom designed Alara technology, that automatically couples with your phone’s internal antennas to dramatically reduce exposure by redirecting radiation away from the user instead of shielding or blocking radio frequency (RF) radiation. Ethos antennas are engineered to resonate at cell phone radio frequencies (RF), so that the cell phone signal is drawn toward the Ethos antenna and away from the user’s head and body as a result, exposure to cell phone radiation (EMF) is reduced without signal degradation.
