Due to various factors that take part in creating your custom headphones or earplugs, there may be a need for a fit adjustment. Please allow at least one week after receiving your headphones or earplugs for your ears to adjust to using them. If you continue to experience fitting issues one week after receipt of your custom order, Eargasm will, at no additional cost, adjust your order to ensure sure you’re getting the best fit possible. Please create a support case by filling out our contact form here. After we confirm you’re eligible, we provide you the option to send your product to our location (within 30 days post receipt of your order) to be covered by the 30-Day Fit Guarantee. Eargasm will send you a prepaid shipping label to return the headphones/earplugs to us. Please allow 3-4 weeks after your order has been returned to our warehouse to make the necessary adjustments and return them to you.*Please note that our 30-Day Fit Guarantee is contingent on us receiving a good scan from our Ear Scanner App. If we do not receive a good scan, we will ask you to submit another scan until we receive a scan we have confidence is complete enough to create your product. If you would prefer to forgo a rescan and use the scan initially submitted, we will do our best to make your product based on your original scan. However, our 30-Day Fit Guarantee above will not apply to your order.
