Whether at home or on a plane, the active noise-cancellation technology of the PowerLocus Lion provides an enhanced listening experience, allowing young music lovers to enjoy great sound even more. Since hearing loss is an irreversible process, PowerLocus Lion ensures safe sound levels that are limited to decibels approved by the WHO (World Health Organization). Three sound modes are available, which can be adjusted depending on the environment in which the music is being listened to: 74, 85, and 94 dB. The wireless headphones are made from hypoallergenic and high-quality materials that meet all global standards for children's products. They are designed for long-lasting durability and are resistant to all types of wear and tear. The headphones are foldable and can accompany you on any journey along with the hard-shell case included in the set.
