First, check the audio source, volume balance settings, and connections. If the cable is detachable, inspect the connectors and reconnect them carefully according to the product instructions. You may also test the earphones with another compatible source. If the problem persists, contact our support team with your order number and a description of the issue.

Try another audio source and compatible cable, if available. Check whether the problem occurs with different tracks or applications, and inspect the connectors for visible debris or damage. Avoid bending or pressing the cable aggressively during testing. If the issue continues, contact support with your test results and relevant evidence.

Channel imbalance can result from device balance settings, an imperfect fit, blocked ear tips or nozzles, the recording itself, or a product issue. Check the left-right balance settings and try a familiar track. If safe and practical, test another compatible source to help narrow down the cause. Contact support if the imbalance persists.

Stop using the product immediately and disconnect it from the audio source if it is safe to do so. Do not continue testing, charge a potentially damaged device, or attempt to repair it yourself. Keep it away from flammable materials if there is a heat or burning concern, and contact our support team for guidance.
