Thank you for viewing! I am selling these because I mistakenly purchased them thinking they were bone conduction headphones. The main unit has been fully charged and only used once for testing. The accessories are unused. I will ship via Yu-Yu Mercari delivery. Please refrain from purchasing if you are looking for a perfect condition item, as this is a personally stored item. I have inspected the item, but there may be oversights. Please check the images for the condition of the item and purchase with your understanding. Please feel free to comment if you have any questions. Thank you. These are open-ear design, lightweight, and safe wireless headphones for children. - Model Name: myFirst Headphones AirWaves - Design: Open-ear design - Target Age: For children - Features: Lightweight and convenient to carry, wireless - Safety: Child-friendly design Bluetooth Kids Thank you for viewing.
