Wireless audio checks
Confirm that the product is charged and within normal range of the source device. Remove obsolete pairings, restart Bluetooth on the source device, and follow the model guide to pair again. Check the source device's audio output and call permissions. If the product is damaged, unusually hot, wet, or producing an abnormal odour, stop use and contact support instead of continuing troubleshooting.
Charging-product checks
Inspect the outlet, adapter, cable, and connected device for damage. Confirm that the cable and device are suitable for the marked port and that all connections are fully inserted. Try a known-good compatible cable or device only when it is safe to do so. Stop use immediately if the enclosure, plug, cable, or port is damaged or if abnormal heat, noise, odour, or discolouration occurs.
Online product guides
The product-guide links below provide getting-started steps, confirmed model information, general safety reminders, and support routes for every product currently listed on the website. Markings and documentation supplied with the commercial product take priority if they differ from general online guidance.
Warranty and service
Eligibility and available remedies depend on the applicable written warranty, market, sales channel, proof of purchase, product condition, and mandatory consumer law. Support may request additional information before providing a troubleshooting step, return instruction, repair route, replacement decision, or other service response.
Response and privacy
Requests are reviewed in the order received and according to their subject and urgency. Information submitted for support is used to respond, maintain service records, protect the website, and meet legal obligations as described in the Privacy Policy.
