With a wide frequency range, the headphone captures deep lows and clear highs without distortion. This ensures accurate monitoring across different audio types, including music, dialogue, and sound effects.

Noise Isolation and Focus

The closed-back design of the HD 300 PRO provides strong passive noise isolation. This helps block out surrounding noise, allowing users to focus fully on their work.

This feature is particularly useful in noisy environments such as live stages, control rooms, and outdoor recording locations. The isolation also prevents sound leakage, which is important during recording sessions.
