Headphones enable the child to listen to music at a low volume in an environment where an open-speaker system is unavailable or undesirable. Music through headphones would enable a child to listen to quiet music while driving in the car, in a classroom, or while taking a school examination when music is not desired for others in the same room. Since the effect of Hemi-Sync Metamusic is more intense with headphones, listening through headphones may become important for some children. Most commercial headphones are made for adult head sizes. They often slip and are uncomfortable for small children.
Several alternatives exist in customizing headphones for infants and toddlers.
Purchase inexpensive headphones with a metal band. Most metal headbands of this type have a bump or metal hump toward the end to prevent extreme movement of the earphones as the band is adjusted for different head sizes. Adjust the metal band to fit the size of the child's head. Secure the band size with masking tape. Use metal cutters to remove the extra length of the band so that it doesn't poke into the child.
