Hello, healthy ears! Puro Sound Labs' lightweight headphones for boys, girls and teens are a safer sound solution for your child's hearing, and the sound is terrifically crisp! Our Puro Sound Labs PuroQuiet Kids' Wireless Headphones promote healthy ears by limiting the volume to 85 dB (the maximum safe listening level as recommended by many organizations, including the Hearing Health Foundation, OSHA, and the World Health Foundation) and blocking out 82% of the background noise. Our design features active and passive noise isolation and is able to block background noise on a level that is comparable to some of the best active noise-cancelling headphones on the market. Enjoy up to 22 hours of play time and 16 hours with ANC (Active Noise Cancellation Function). A volume limiting cable compatible with non-Bluetooth devices is also included for continuous use in case the battery dies. The super-soft vegan leather-wrapped headband and ear cushions ensure long wearing comfort, combined with a smooth sliding arm so that boys, girls and teens can adjust the headphones to suit their head sizes and shapes. Its AL6063 aluminum body enhances durability to withstand rough play, and the lightweight construction, only weighing around 169g, creates almost no pressure on young heads! The purchase of our product also includes a USB charging cable, a volume limiting 3.5mm audio cable, a hard cover travel case, and a user manual. Taking advantage of PuroQuiet ANC technology, 85 dB volume limiting, and 82% noise isolation, kids can listen to true-to-life audio without the need to volume up in noisy environments, reducing the risk of noise-induced hearing loss or partial deafness.
