Replacing the earpieces may improve the symptom.
The medium-size silicone ear pieces are attached when purchased.
Choose an appropriate ear piece from the five sizes (S, MS, M, ML and L) to enhance your listening experience and for the best fit.
Incorrect ear piece size can result in sound leakage and lack of bass.
Check that the ear piece is securely attached as shown in the figure.

If the ear piece is not securely attached, it may slipped off when in use and remain in your ear. If the ear piece remains in your ear, be careful not to push it further into your ear.

The effect may not be noticeable due to the surrounding environment.
The noise canceling function reduces the noise by generating sound that is exactly opposite in phase to the noise from the external environment.
Although the effect on low frequency noise such as noise from vehicles and air conditioners in a room is noticeable, it may not be as noticeable in a quiet place and with certain types of noise.
Move to another location and check the effect.
