You can perform the following actions to improve noise cancellation:

1. Try different sizes of ear wings to ensure they fit well and create a tight seal. If one ear wing doesn't fit properly, try mixing sizes—for example, using a size 2 ear wing on the left and a size 3 on the right.

2. Ensure the ear wings are positioned correctly for a tight seal. Check for optimal placement—improper positioning can affect noise reduction.

3. Test the earbuds in different environments to determine whether environmental factors are causing the variations.

4. Liberty Buds are semi-in-ear Bluetooth earbuds designed for comfort during extended wear and do not come with separate ear tips. Because ear shapes vary, the fit may differ from person to person, resulting in varying noise cancellation performance compared to in-ear Bluetooth earbuds.

Note: Noise cancellation reduces ambient noise but does not eliminate it completely. Some background sounds may still be heard, especially in very loud environments.
