We are currently focused on the wider market of adults, and therefore Muse was originally designed to fit an adult head shape/size. We have considered how to approach Muse for a younger demographic, and may investigate it further at a later date.
Using Muse with Children requires a great deal of investigation about privacy and compliance specifically with the CIPA (Children's Internet Protection Act). Bio-metric information is particularly sensitive, so we require users to agree to our end user license agreement, so with that, we recommend Muse to those 13 and up.
The dimensions of the Muse headband is 52cm to 60cm.
