If you feel that the soundcore P41i's noise reduction is not effective, you can find a solution in this article.

1. Experiment with different sizes of ear tips to find the best fit and achieve a tight seal. If one earbud doesn't fit well, try using different sizes for each ear, such as medium in one ear and large in the other.

2. Use the Fit Test in the soundcore app to check how well your earbuds fit. A poor fit may affect the quality of noise cancellation.

3. Turn on Adaptive ANC on the Device Features page: Noise Cancellation > Mode > Adaptive ANC.

4. Turn on ANC Personalized to Ear Canal on the Device Features page: Noise Cancellation > Mode > ANC Personalized to Ear Canal.

5. Test the earbuds in various environments to see if there's a difference in performance. Since ear canals can differ between ears, try different ear tips for each ear if the Fit Test fails.

Note: In noisy environments or at high volumes, noise cancellation might seem less effective.
