For both returns and warranty claims, your shipment must include your product in its entirety (your earbuds and charging capsule, etc.).
While not explicitly required, we encourage you to ship back everything that you received from your original purchase even if the packaging is missing.
Please refrain from sending single earbuds or charging capsules alone for returns or warranty requests for a full product. If these items are received alone they might be rejected and sent back to the return address.
