Clearing customs for non-EU shipments
For non-EU headphone shipments, import customs clearance is necessary in order to receive the headphones at our headquarters. This process can take up to 5 business days, depending on the workload of the Latvian customs and carriers.
NOTE! Make sure you have sent in all the details listed above, in order for our team to be able to clear the customs process.
If you receive a notification that there was an attempted/failed delivery or if it is stuck at customs, please, know that our logistics specialist is working on it. If there will be additional information needed, we will get in touch with you!
Important to know before shipping your headphones
- Due to official customs regulations, parcels that are delivered to Sonarworks from outside of the EU will be shipped back to the same address from which the parcel was sent. Meaning, the return shipping address for Individually calibrated headphones will be taken from your initial shipping documents and NOT the shipping address specified in the Sonarworks Store order details.
-
When sending in headphones for individual calibration, it is important to make sure the ear pads are in mint condition; replacing them before sending is recommended. In our experience, it is not burn-in that causes a change in freq. response over time (as opposed to speakers, where burn-in is very important). Instead, worn ear pads are gradually affecting the sound. If your calibration is done on fresh ear pads, you will always be able to return to the original calibration performance simply by replacing them.
-
For rare and specific headphone types (electrostatic, vintage, dynamically adaptive environment tech, etc.), make sure to include all the necessary headphone amplifiers, custom cables, and anything else that is required for your specific model to work - we might not have those accessories in-house to work with.
- Individual calibration service is NOT supported for earbuds and in-ear headphones. If you are unsure about the type of your headphones, please contact our support before purchasing the services.
