BuddyPhones Wave are the safe, comfortable, and sturdy Bluetooth headphones you've been waiting for. With a 24-hour battery life, these headphones can be used for 10 days (2-3 hours each day) without needing to be recharged. They are also adjustable, allowing them to grow with your child, and the hypoallergenic cushions keep them soft and comfortable for many years. They work with all Bluetooth devices, such as iPads, iPhones, Kindle Fire, DVD players, and more. The Wave Bluetooth headphones offer a child-friendly volume limit. You can set the volume to 75 dB for toddlers, 85 dB for children, and 94 dB for noisy environments, such as on an airplane. Additionally, there is a StudyMode: a protected technology that highlights and clarifies spoken words at a maximum of 94 dB, which is particularly useful when learning new languages.

They are extremely durable and offer IP67 protection against water, making them capable of withstanding the daily use by children without any issues.
