Prenatal Belly Speaker by Aura Baby™

Aura Baby Harmony™ Prenatal Belly Speakers are lightweight speakers designed to rest comfortably on your pregnant belly so you can share music, stories, familiar voices, and recorded messages during pregnancy. Harmony™ connects directly to a compatible phone or audio device and can be worn using the included Sonobond™ adhesives or tucked securely into maternity clothing.

Harmony™ is recommended for use from approximately 18 to 40 weeks of pregnancy. Fetal hearing develops gradually during the second trimester and continues maturing throughout pregnancy, so what your baby can perceive may change as pregnancy progresses. Always follow your healthcare provider’s guidance for your individual pregnancy.

Fetal hearing develops progressively during pregnancy, and external sounds can reach the womb after passing through the mother’s tissues and surrounding fluid. Harmony™ is designed to provide a gentle way to share music and familiar sounds during this stage. It is intended for prenatal bonding and does not measure or confirm what your baby can hear.

You can play music, lullabies, audiobooks, stories, podcasts, personal voice recordings, or other audio from a compatible phone, tablet, computer, or digital music player. Many parents use Harmony™ to share favourite songs or recordings from partners and family members.

Yes. You can play recorded messages from parents, siblings, grandparents, or other loved ones through Harmony™. Simply record the message using your phone or another compatible device and play the recording through the belly speakers.

Harmony™ uses a standard 3.5 mm audio connection and includes USB-C and Lightning adapters for compatible phones that do not have a headphone jack. This allows Harmony™ to work with many current and older iPhone and Android devices. Compatibility can vary between individual phone and tablet models.

No. Harmony™ is a wired prenatal belly speaker system and does not require Bluetooth pairing, a dedicated app, Wi-Fi, or a subscription. You can play audio from compatible apps such as Spotify, Apple Music, YouTube, podcast or audiobook apps, as well as downloaded music and saved recordings.

No. Harmony™ connects directly to a compatible audio device and does not require separate charging or batteries for the speakers. Simply connect Harmony™ using the appropriate audio connection or included adapter and begin playing your chosen audio.

Connect Harmony™ to your compatible phone or audio device, choose the audio you would like to play, and set the volume to a moderate level before placing the speakers on your belly. You can then tuck the speakers into maternity clothing or attach them to clean, dry skin using the included Sonobond™ adhesive disks.

Place the two Harmony™ speakers comfortably and securely against your belly. They can be attached directly to clean, dry skin using the included Sonobond™ adhesives or tucked into maternity pants, a pregnancy support garment, or similar clothing that keeps them comfortably in place. Harmony™ is not designed to locate your baby’s position.

Start with clean, dry skin that is free of lotions and oils. Remove the paper backing from a Sonobond™ adhesive disk and press the exposed side onto the Harmony™ speaker. Remove the remaining transparent protective layer and gently secure the speaker to your belly. After use, return the adhesive surface to its protective sheet so it can be reused.

Sonobond™ adhesives are designed for multiple uses, although longevity varies depending on skin type, natural oils, frequency of use, and care. If an adhesive begins losing tackiness, gently running a wet finger over the adhesive surface can help remove accumulated oils. Allow it to dry completely before using it again. Replace the adhesive when it can no longer hold the speaker securely.

Sonobond™ adhesives are made from a skin-safe, hypoallergenic-grade gel designed for skin contact. Individual sensitivities can still occur. Use Harmony™ on clean, dry skin without lotions or oils, and discontinue use if irritation develops.

Harmony™ incorporates a sound-dampening design and volume-limiting feature for prenatal use. Set the volume on your phone or audio device to a moderate, comfortable level before placing the speakers on your belly. There is no need to increase the volume simply because the sound is travelling through the abdomen, and louder does not mean better.

Aura Baby™ recommends limiting Harmony™ use to approximately one hour per day. This can be enjoyed as one listening session or divided into shorter periods. If you have questions about introducing any new prenatal practice, consult your healthcare professional.

Yes. Harmony™ includes an audio splitter for shared listening. Connect the splitter to your compatible audio device, plug Harmony™ into one side, and connect a pair of adult headphones to the other side so you can enjoy the same music, story, or recording at the same time.

There is no specific genre you need to play. Choose music, stories, lullabies, or familiar voices that create an enjoyable and relaxing experience for you. Classical music is not required. Harmony™ is designed for bonding and shared listening rather than to produce a specific developmental outcome.

Harmony™ is designed to support meaningful prenatal bonding and shared listening experiences. Aura Baby™ does not claim that prenatal belly speakers increase intelligence, improve language development, or produce a particular medical or developmental outcome.

No. Harmony™ is a prenatal listening and bonding accessory, not a fetal Doppler or medical monitor. It does not detect or measure fetal heartbeat, movement, hearing, or wellbeing and should never replace prenatal appointments, fetal monitoring when medically indicated, or advice from a qualified healthcare professional.
