FAQ
Is it available now?
Not yet. 31st St Project is preparing for launch and crowdfunding.Is it designed for side sleepers?
Yes. The system is designed with side sleeping in mind, using small and soft in-ear components while keeping the larger wireless electronics away from the ear and pillow.How is it different from flat-speaker sleep masks?
31st St Project delivers audio through small in-ear components rather than flat speakers positioned inside the mask. The audio stays with your ears as you change position, while properly fitted in-ear audio can provide passive isolation and help reduce sound leakage compared with flat-speaker designs.Are the earbuds detachable?
Yes. The short-lead earbud assemblies detach close to the ear using magnetic connections.Is the sleep mask washable?
The earbuds and electronic components are designed to be removed so the silk mask can be cleaned separately. Final washing and care instructions will be provided with the finished product.Have another question?
