The headbands do stretch a bit, so if you are between sizes, we suggest going with the smaller size. Having the proper size headband, with a snug fit, is crucial not only for comfort but for sound too. If the headband is too loose it will cause the speakers to move around. Our SleepPhones® Headphones come in our signature SheepCloud™ fabrics, both of which are 95% polyester and 5% spandex. Here is a short demonstration video on how to find the proper size for you. If you order the wrong size, we would be happy to exchange it for you. Hereis more information about our exchanges and warranty

What are the care instructions for SleepPhones®?
We recommend that the headbands be washed occasionally to remove the build-up of oils, which causes the headbands to stretch and lose their proper fit. Please view our quick video for details on removing and reinserting the speakers.

Our SheepCloud™ fabric does not contain any animal and plant fibers that may cause an allergy problem. They are not treated with any fabric softeners or fire retardant chemicals.

  • Machine Washable: Any temperature is fine, but warm water is preferred
  • Fabric Softener: Not recommended, as it reduces the wicking properties that keep you comfortable at night
  • Bleach: Not recommended
  • Machine Dry: Low heat preferred
  • Iron: Do not iron, as the fabric will melt on high heat
  • Dry Clean: Do not dry clean, as this increases flammability
  • Flammability: Our fleece is much less flammable than other fleece on the market. A certificate for confirmation to the flammable fabrics act is available upon request.
