3. Sound leakage: Ensure the earcups are properly positioned over your ears and the headband is adjusted for a secure fit. Note that these headphones may leak more sound than some other closed-back models.
4. Uncomfortable fit: Adjust the headband for a more comfortable fit. If you still experience discomfort, consider replacing the earpads with a different type or material.
