It is not recommended to use wireless headphones when pregnant. We find that the best option, in this case, is wired headphones, which do not emit radiation and transfer sounds directly into the ear canal. You should also avoid using any other type of device (such as a cell phone) when in close contact with your body for extended periods. If you're thinking about buying wireless headphones for use while pregnant, we suggest that you consult your physician to ensure it is safe and there are no other conditions that should be considered.
