How do I figure out what size to buy?
chart of SleepPhone sizes for hats to get band size

Almost everyone fits into the one size fits most. 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™ Knitted Fabrics in two different blends. The fleece is 95% polyester and 5% spandex and the breeze is 88% polyester and 12% spandex. You can find a short demonstration video on how to find the proper size measurement on our site at: Sizing. If you order the wrong size, we would be happy to exchange it for you. Please find more information on our site at: 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: Care-instructions

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.

    Are the speakers relatively flat?
    The speakers are not completely flat, but are very thin discs that are enclosed in felt. The speakers are a special design made exclusively for us by a company that also makes high-end audiophile quality speakers. We cannot claim audiophile status, but most people are pleasantly impressed with the sound quality. Most people cannot feel them when sleeping on their side.

    Are the right and the left speakers clearly marked?
    The right side speaker has red stitching on the fabric square and the left side speaker has green stitching on the fabric square. It is necessary that the speakers be placed properly in the headband since they are stereo and play side specific sounds, which is very important if the user is listening to music utilizing binaural beats technology or any other recordings that have side specific tones. The speakers are moveable within the headband and can be moved in to proper position over each individual’s ears. Please view this short video for more information regarding Speaker Placement.

    Have there been different version of SleepPhones®?
    Yes. They are slightly different. Please visit our SleepPhones® Generations page to see the different versions.

    Do SleepPhones® mute external noises?
    SleepPhones® were constructed to minimize ambient noises. Users listen to music or white noise to help them to relax, which enables them to fall asleep faster and helps to reduce background noises. However, the product does not have any external equipment to eliminate noise. SleepPhones® were designed to be noise blocking, not noise canceling.

    Are binaural beats an effective way to sustain sleep?
    Research on binaural beats shows that it is quite effective in inducing the frequencies associated with sleep in your brain.

    When listening to soundtracks that utilize binaural beat technology, you may be aware of a soft humming which is actually the binaural beats. Try to not focus on the sound. Ideally, they should be barely audible when you listen to the soundtracks that the binaural beats are incorporated in to.

    There are other factors that can impact binaural beats, such as Dolby technology or certain sound enhancements that your music player may use. Those technologies need to be turned off. Sometimes computers will read music files in different ways, and going from one medium to another using different file types and file compressions will also impact the binaural beats. We agree that it's a complicated technology. That's why we offer CDs that will definitely transmit the specific sounds you seek - as long as they are played on a CD player that does not distort the sounds with enhancements like Dolby.

    We welcome you to do your own research online regarding binaural beats. We have heard from many very satisfied customers, and their comments are listed in the testimonials section of our website. Testimonials

    Can you still hear an alarm clock while using SleepPhones®?
    Yes, users will be able to hear an alarm clock. It will only be slightly muffled by the fabric around the ears. We feel that being able to hear a fire alarm or a child monitor in the middle of the night is important. SleepPhones® were designed to be noise blocking, not noise canceling.

    Can SleepPhones® be used for purposes other than sleep?
    Absolutely! Since the speakers have a full frequency response, SleepPhones® can be used to listen to music, meditation, hypnosis, self-improvement, biofeedback, audiobooks, or podcasts. They are a great travel companion!

    Can SleepPhones® be used by someone who is hard of hearing or who uses hearing aids?
    SleepPhones® can play music quite loudly, so user’s can turn up the volume to compensate for mild hearing loss. For customers listening to music utilizing the binaural beats technology, the benefit may not work as well if the hearing loss is not the same in the left and right ears since the binaural beats are based on a stereo sound principle.

    Many people with hearing aids have reported that SleepPhones® work well with them. However, SleepPhones® do not have the T-switch technology. Individual results will vary.


    Is it safe to use SleepPhones® Wireless Bluetooth® technology? What about EMFs?
    In a word, yes. We feel confident that all of our products, including the SleepPhones® Wireless, are safe. SleepPhones® generate much much less EMF (electromagnetic fields) than cell phones, so the risk is minimal. Dr Lai has written an extensive reply to this question, which can be found at the following link: EMF

    We want to point out that cell phones emit 200 times more power than the Bluetooth® chip that we use. So while the safety tips apply to cell phones, they do not apply to our Bluetooth® device. For Bluetooth® devices, the WHO (World Health Organization), CDC (Centers for Disease Control and Prevention), FCC (Federal Communications Commission), FDA (Food and Drug Administration), Bluetooth SIG (Bluetooth Special Interest Group) or IARC (International Agency for Research on Cancer) have not found it necessary to issue any safety advice.

    How do I protect against hearing damage?
    As with any headphones, you should not listen to sounds at a volume of 85 dB or higher. 85 dB is equal to the sound of a hairdryer or lawnmower. Studies show that you can tolerate only up to 8 hours a day of music at 85dB before risking hearing loss. For more information, please visit the following link: Decibels
