LC-dolida Bluetooth Sleep Masks are a two-mask sleep and travel set designed to block light and play audio, with Bluetooth 5.4 and a 6-layer blackout construction.
Light, nearby sounds, and pressure around the eyes can make it harder to settle in for rest. These masks combine an eye covering with built-in Bluetooth audio for sleep, travel, office naps, or relaxing at home. The two-mask format also gives you a separate mask to keep in a travel bag or at another rest spot.
Yes. The contoured eye cups use a 15 mm-deep cavity and soft memory foam to create space around the eyes and eyelashes. This shape is designed to avoid pressing directly on the eye area while resting on your side, and the mask combines that contour with an integrated audio feature. The eye cups provide a defined space for the eyes rather than a flat panel resting across them.
The blackout construction uses six layers of light-blocking fabric and extended, flexible nose wings to help reduce light leakage. Bluetooth 5.4 connects the mask to audio for music, podcasts, or white noise; the stated transmission rate is 900Kbps. The speakers are integrated into the mask, so there are no bulky earpieces to wear inside the ears. This combination is intended for people who want to cover their eyes while listening to audio during rest.
The set includes two Bluetooth sleep masks, a portable pouch, and noise-canceling earplugs with each mask set. The pouch gives you a way to keep the mask and accompanying items together when packing or storing them. The pair can be divided between home and travel, or used in different places where you take a rest. The set is positioned for frequent travelers, office naps, and home relaxation, and its included items make it a ready-to-give rest and travel set.
The inside is breathable, hypoallergenic bamboo cotton, while the outside has a shiny fabric shell. The bamboo-fiber lining is moisture-wicking and dries three times faster than cotton, a useful detail for a mask worn for extended rest. The materials are described as renewable and intended to help reduce plastic waste. Together, the inner and outer fabrics give the mask a soft, silky feel against the skin with a distinct smooth-looking exterior.
LC-dolida sleep masks suit side sleepers, light-sensitive sleepers, and people who want audio alongside eye coverage, whether at home, during travel, or for an office nap. The two-mask set includes a pouch and noise-canceling earplugs, while the contoured design, blackout layers, and integrated Bluetooth audio bring the key rest features into one set.
