This is a great bluetooth headset, built into a little girl's pink unicorn headband. It has a control panel on the left side, a pair of small speakers built into the headband, and is charged using a USB charging cble (included). The circuitry limits the volume to 85 db, making it safer for the child's hearing. It is powered by a 200 mAh rechargeable bettery, which will provide 6 to 8 hours of operation, then it takes only about 2 or 3 hours to recharge.
It will work with almost any bluetooth-enabled audio device (phone, tablet, MP3, computer, etc). It was purchased as a birthday present for our soon-to-be 6 year old granddaughter (shhh, don't tell her). She will really love it and have hours of entertainment using it.
