Joythink is a silk-and-velvet sleep mask with Bluetooth 5.3 wireless headphones, designed to block light and let you listen while resting.
Joythink combines an eye mask and wireless audio headband for people who want to listen to music as they settle down to rest. It is made for bedtime as well as naps during travel, office breaks, or night shifts. The design is also suited to yoga, meditation, and relaxation, and the product is marketed for children and side sleepers.
Joythink connects to a device through Bluetooth 5.3 and plays audio through ultra-thin stereo speakers built into the mask. The earphones can be adjusted to sit in a comfortable position, and the wireless design keeps the listening setup integrated with the sleep mask. This makes it suitable for listening before sleep or during a nap without wearing separate headphones.
The built-in 200mAh battery provides over 16 hours of music playback following a 2-hour charge. Charging uses a Type-C port, making the mask suitable for extended listening during travel, overnight rest, or a shift with time for a recharge between uses.
Adjustable magic straps are designed to fit most head sizes, so the mask can be secured to suit the wearer. A zipper pocket holds the headphone wires and Bluetooth module; remove these audio components before cleaning the mask. A silk pouch is included for storage and portability.
Joythink suits children and other wearers whose head size works with its adjustable straps, as well as side sleepers and people who want a mask with integrated audio for rest, travel, meditation, or naps. Its silk-and-velvet mask, wireless stereo speakers, and removable audio components bring light blocking and listening together in one sleep accessory.
Q: How long does the Joythink sleep mask play music?
A: The Joythink sleep mask provides over 16 hours of music playback from its built-in 200mAh battery after a 2-hour charge through its Type-C port.
Q: Can the Joythink sleep mask’s audio components be removed for cleaning?
A: Yes. The Joythink sleep mask has a zipper pocket that holds the wires and Bluetooth module, which can be removed for cleaning.
