Powerfoyle™ from Exeger. More light, more power
These headphones charge when exposed to light, from sunlight to electric light! Powerfoyle™ solar cell material in the headband draws energy from the sun to charge the battery – and it can even be charged by electric light. A full charge provides up to 80 hours of playtime, so you can keep going, even in low light.

Cool and comfortable fit for an active lifestyle.
Run, walk, roller skate! The comfortable headband won’t slip during movement, and the soft, breathable ear cushions are filled with a cooling gel. The ear cushion cover can be removed for easy cleaning, so you can keep them feeling fresh.

Great sound, even at low volume, with dynamic bass
The 40mm drivers deliver rich sound and good passive noise isolation thanks to the over-ear fit. If you like a good bass line, activate Dynamic Bass via the Philips Headphones App and enjoy the full power of your favorite music, even when listening at low volumes.
