No, the RF is very low power and can safely be active on your face for long periods. We've done a lot of investigation and verification with safety. While doing R&D the first 2 months we collected hundreds of hours of data on ourselves with various configurations, so we made sure it was safe before :)

Also, the RF transmission only activates when you're actively dictating.

Not gonna lie, this answer made me question the safety more than I would've prior to reading it.

If you actually have done any documented research on it, might wanna link to it.
