With the Junior series, OTL Technologies offers foldable headphones specially designed for sensitive ears and tested with a volume limit of 85 dB for children aged 3 to 7 years. OTL works with some of the world's largest licensing partners. Together they give each model a cool and colourful look (including Pokemon, Super Mario, Harry Potter, Batman, Peppa Pig, Paw Patrol, and more). In addition, the headphones are compatible with all devices thanks to their 3.5 mm plug.
