myFirst BC Wireless Lite headphones are waterproof, robust, wireless bone conduction headphones specially designed for children. These headphones transmit sound through the cheekbones to the inner ear, rather than through earbuds into the ear canal. This ensures a perfect fit, preventing sound damage and keeping the ear canal open to ambient sounds. This keeps your child alert to sounds while playing (outdoors) or in traffic, and allows you, as a parent, to still hear if you speak while listening. The volume is adjustable. The myFirst BCW headphones connect to other devices via Bluetooth and are a perfect pairing with the myFirst Fone R1(s) smartwatch-phone or myFirst Voice. Enjoy your favorite music or audiobooks endlessly!
