Kids' wireless on-ear headphones

Safe, fun and travel-friendly
With colourful LEDs on the earcups and a fun wireless audio-share feature, these headphones are
built for kids to love. They're volume-limited for young ears, and a special travel mode lets kids
listen safely in nosier environments, too.

• On-ear wireless headphones
• Volume limited to 85 dB
• LED lights. Audio share
• Durable and foldable

Always safe, always fun. Volume limits for home and travel*

Specially 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 use

Big, 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 lights

Colourful 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.

Philips Headphones app with parental controls

Our 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.

RCS-certified recycled plastic. Responsible packaging

We use post-consumer recycled plastics in this product, and our packaging is plastic-free. Inserts
are printed on recycled paper with soy-based ink, and the packaging itself is made from
FSC-certified recycled cardboard.

Wireless audio sharing doubles the fun

If 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 foldable

Made 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.

Long battery life and easy wireless connections

From 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 family

A 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 signature

From 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.
