Frequently Asked Questions
Compare fit, audio features and care before choosing your LC-dolida sleep mask.
Choosing and using your sleep mask
How does a Bluetooth sleep mask work?
A Bluetooth sleep mask combines an eye mask with built-in wireless speakers. Pair it with a compatible phone or other Bluetooth device to listen to music, podcasts or guided meditation while your eyes are covered.
Which features should side sleepers compare?
Compare speaker thickness and position, padding, eye-cup depth and strap adjustment. Comfort depends on the model, your fit and your pillow. The bamboo cotton cushioned model has 12 mm ear cushions; other models use different padding and speaker designs.
Can I use white noise without a phone?
The LC-dolida white noise sleep mask offers eight built-in sounds without a phone connection. Other Bluetooth models need a paired device to stream white noise or other audio.
Can I wash a Bluetooth sleep mask?
Cleaning instructions vary by model. Check the product instructions before washing and remove any detachable speakers or electronic parts as directed. Do not immerse or wash the electronics.
How long does the battery last?
Playback time varies by model and use. Listed specifications range from 8–10 hours on some masks to up to 16 hours on the bamboo cotton cushioned model. Check the individual product page for its playback and charging details.
Which sleep mask should I choose?
Choose mulberry silk for a smooth fabric feel, bamboo-cotton for soft breathable comfort, or the white noise model for eight built-in sounds and a sleep timer. See our comparison guide for each model’s features.
