One aspect that some users may find less favorable is the open-back design, which allows sound leakage and does not provide isolation from external noise. As a result, these headphones are best suited for quiet environments or personal listening sessions. Additionally, the HD 660 S may require a bit of power to reach their full potential, so pairing them with a quality headphone amplifier is recommended for optimal performance.
