Built-in Bluetooth Headphones: The headband has integrated wireless headphones with excellent sound quality. You easily connect them with your smartphone. The sleep mask and headphones are detachable, just remove the headphones to clean/wash the mask.

Soft and comfortable: This Bluetooth sleep mask is made of soft fleece material, which feels pleasant against the eyes. The eye mask has a cute penguin design.
Complete blackout: The sleep mask does not press on the eyes and effectively blocks out light. Together with soothing music, a podcast, or audiobook in the headphones, sleep headphones create optimal relaxation.
