If you're experiencing unbalanced sound with your C40i earbuds, follow these steps to enhance your listening experience:

1. Ensure the earbuds are worn in the correct orientation.

2. Adjust the position of the earbuds in your ears. If the speakers of the left and right earbuds do not align with your ear canals, you may notice differences in volume and sound quality between the two sides.

3. Reset the earbuds. To do so, return them to the charging case and leave the case open. Then, press the button on the case for at least 5 seconds until the LED turns red. The LED will then flash red three times before switching to a rapid white flash, indicating a successful reset.
