LC-dolida’s award-winning silk Bluetooth sleep mask is designed to block out 99.99% of light and deliver wireless audio, with 22-momme mulberry silk and Bluetooth 5.4 speakers made for side sleepers.
Light, sound, and an uncomfortable fit can all get in the way of resting at night or during a short break. LC-dolida combines an eye mask with wireless headphones in one wearable design for nighttime sleep, office naps, and travel. Its black fabric and extended face coverage are intended to create a darker resting space, while the built-in audio lets you listen to music, meditation, or other sleep sounds without separate headphones.
The mask is designed to block 99.99% of light using extended coverage and a triangle-wing shape that contours around the face. Its larger coverage is intended to conform to different facial shapes, helping create a blackout environment for rest. The fabric is described as breathable and designed to help keep you comfortable through the night.
Yes. The mask has built-in Bluetooth 5.4 headphones with 32 mm stereo sound, and its 0.2 in (5.08 mm) speaker profile is designed for side sleepers. Use the wireless connection for music, meditation, sleep sounds, or calls while resting; the stated connection range is up to 15 m (49.2 ft), and playback lasts up to 15 hours.
The speakers can be moved inside the mask to align them with your ears. Adjust their position while wearing the mask to find a fit that feels comfortable and keeps the speakers in place. This built-in, adjustable arrangement brings the audio and eye covering together without requiring separate headphones.
LC-dolida uses 22-momme mulberry silk for the mask’s padded fabric. The silk is described as tested for softness, brilliance, and durability, and the design is intended to help regulate temperature during nighttime wear. The package also includes two noise-canceling earplugs and a portable storage bag for carrying the set when traveling.
This mask suits adults looking for a combined sleep mask and wireless listening option for home, travel, or office naps, especially those who sleep on their side and want a low-profile speaker design.

For nighttime rest and listening in one wearable item, it brings a silk eye covering, adjustable Bluetooth speakers, and travel accessories together.
