To fix this issue, please try the following steps:

1. How well the earbuds fit may affect levels of background noise, please make sure you follow the steps below to wear your earbuds correctly and stably.

- Look at the L/R logo on the back of the earbuds to ensure that the left and right earbuds are being worn on the correct sides. Rotate the ear hook and turn the earbuds while wearing them and find the most comfortable position.

- Try other sizes of ear tips to ensure the size you're using fits well and creates a tight seal. If one of your earbuds doesn't fit well, please try a combination of the ear tips, such as medium on the left and large on the right.

2. Open the app, switch to "Manual Mode", and adjust to "Min Noise Cancellation" or select the corresponding "Ambient Sound" mode to see if it helps at all.

3. Try these earbuds with a different audio input and Bluetooth device (phone/tablet/etc.) and see if the issue persists.
