SCIENCE-BACKED STUDIES ON SOUND THERAPY FOR ILLNESS SUPPORT
With Rainbow Sounds Sound Therapy Bowls and training, you can bring sound therapy into your daily life as a supportive tool for health and well-being. Playing your bowl is both accessible and versatile—you can use it as a personal practice (self-guided sound meditation) or invite a family member to play for you, creating either an interactive or a restful, passive session.
Many of our customers use Rainbow Sounds Sound Therapy Bowls as part of their wellness routines, supported by a growing body of scientific research. Below are some common areas where sound therapy is being studied, with peer-reviewed findings you can explore.

To use your HSA or FSA debit card, add products to your cart as usual. At checkout, select “Flex | Pay with HSA/FSA” as your payment option, enter your HSA or FSA debit card, and complete your checkout as usual. If you don’t see “Flex | Pay with HSA/FSA,” you may be in Shop Pay. Select “checkout as guest” to view more payment options.
If you don’t have your HSA or FSA card handy, still select “Flex | Pay with HSA/FSA” as your payment method. Enter your credit card information and Flex will email you an itemized receipt to submit for reimbursement.
The key here is to make sure you are logged out of ShopPay. One of the easiest ways to do this is to go through checkout in an incognito window.
HSA/FSA cards are debit cards, and the most common reason for declines is insufficient funds. Reach out to your HSA/FSA administrator to confirm your balance.
Please forward us the request from your FSA, and we will work with the Flex team to issue you a new receipt.
Please check your spam folder, as sometimes emails from notifications@withflex.com may be automatically filtered as spam by some email service providers. If you still can’t find it, please email support@withflex.com and let them know the email address associated with your order.
No, unfortunately, this isn’t a supported feature right now. If there are insufficient funds in a single HSA or FSA account, you can instead enter a credit card on the Flex checkout page. You will receive an itemized receipt and/or Letter of Medical Necessity from Flex, which you can submit for reimbursement.
Sales tax for eligible items is also covered by HSA/FSA funds. If the customer has a split cart, the tax will be divided among the cards based on the items.
