Always safe, always fun. Volume limits for home and travelSpecially designed to be extra safe for young ears, these headphones have been limited to 75 dB for listening at home or while studying. For listening in noisier environments outside of the home, parents can use the Philips Headphones app to set an 85 dB travel-mode volume limit.Kid-friendly comfort and easy to useBig, round control buttons on the bottom of the earcups make it easy for kids to use these headphones, while smaller earcups with soft earcup cushions make them comfortable to wear. The cushioned headband adjusts easily for a perfect fit and features dots on the back that help children see which way round to put the headphones on.Colourful design with LED lightsColourful LEDs in the earcups combine with the multi-coloured design of these headphones to make them stand out in all the right ways. The LEDs can be set to glow different colours: brilliant for kids who want to express their own sense of style.Wireless audio sharing doubles the funIf your kid's friends also have a pair of Philips K4200 headphones, they can create a wireless daisy chain between the headphones and listen to the same audio. One pair of headphones is connected to the smart device they want to listen from, and then both friends need to press the multi-function button four times to enter audio-sharing mode.Tough, durable and foldableMade from durable, non-toxic materials, these headphones are built to withstand the rigours of daily use by kids. When not in use, they can be folded flat for easy storage in a drawer. Or you can fold them flat and inwards, creating a compact bundle that easily fits into pockets and bags.Philips Headphones app with parental controlsOur companion app can be used to set playtime limits, so kids don't listen for too long. Or use the app to switch these headphones from their default setting where volume is limited to 75 dB to a travel mode that limits volume to 85 dB.Long battery life and easy wireless connectionsFrom weekend fun to homework, these headphones keep up with up to 45 hours of play time from a full charge (which takes 2 hours via the included USB-C cable). A dedicated BT button on the headphones makes it easy for kids to pair with their devices, and multipoint connectivity lets them connect to more than one device at once.Clear calls with friends and familyA built-in microphone lets kids take calls with family and friends. A dedicated mic picks up the sound of their voice, while a noise-reduction algorithm quietens some of the background noise from the world around them.Warm, natural sound. Philips sound signatureFrom films to music, they'll love what they hear! These on-ear kids' headphones feature large 32 mm drivers, tuned to the Philips sound signature. Whatever they're into, they'll enjoy a warm, natural sound with deep bass.Thoughtful design. Responsible packagingThese headphones feature recycled materials, while our plastic-free packaging uses FSC-certified recycled cardboard and soy-based ink.
