The BuddyPhones Cosmos+ is our premium flagship wireless kid's headphones. Switch on active noise cancellation to block out distracting background noise allowing the child to listen clearly without turning the volume up needlessly high. To protect the childs hearing, the BuddyPhones Cosmos+ has 3 volume limiting levels to choose from to suit the childs age or when a boost is needed in noisy surroundings, such as on a plane. Our patented StudyMode helps isolate voices from other sounds, producing crisper, clearer vocals for studying or watching lessons. Combine the boom mic with active noise cancellation and StudyMode to greatly boost concentration level and productivity. The dual connection feature which allows the headphones to be connected both wired or wirelessly is a life saver if you ever run out of battery.
