These wireless headphones with microphone are ideal for talking to friends and family on a video call, too. Since 1959, Barbie’s purpose has been to inspire the limitless potential in every girl. We have always known that a small doll can make a big impact. Today we bring power to our purpose, not only as a global icon, but as an advocate for real social and environmental change. As part of Mattel’s purpose to empower the next generation, Barbie has committed to three priorities: representation, empowerment, and environmental impact.
