Open the charging case lid; the earbuds should automatically enter pairing mode. Enable Bluetooth on your device and select the model name (e.g., PSIER S12, CT12) from the list.
Place the earbuds back into the charging case and keep the lid open. Long-press the reset button (or the touch control areas on both earbuds) for about 10 seconds until the LED indicators flash red and white, indicating a successful reset.
Check the charging contacts on both the earbud and inside the case for dirt or debris. Clean them gently with a cotton swab. Ensure the case itself is charged.
Many PSIER models, such as the S12 and X13, feature IPX ratings (e.g., IPX8 for swimming or IPX6 for sweat resistance). Refer to your specific model's manual to confirm its water resistance level before exposing it to water.
