NDH-81 specifications

The NEC NDH-81 is a high-performance headphone designed to deliver an exceptional audio experience, using a blend of advanced technologies and ergonomic design. This model is recognized for its professional-grade sound quality and is particularly appealing to audiophiles and sound engineers alike.

One of the NDH-81's standout features is its closed-back design, which provides excellent sound isolation. This allows users to immerse themselves in the music without distractions from ambient noise. The headphones utilize a well-engineered bass reflex system that enhances low-frequency response while maintaining clarity across all ranges. This ensures that listeners can experience deep bass without sacrificing the integrity of mid- and high-frequency sounds.

The NDH-81 is equipped with large, high-fidelity 38mm dynamic drivers. These drivers are meticulously crafted to ensure a balanced sound stage, making it suitable for critical listening and professional audio applications. The headphones have an impressive frequency response range, typically between 5 Hz to 40 kHz, which encompasses the full spectrum of human hearing. This broad range allows for accurate reproduction of audio signals, capturing nuances that are often lost in lower-quality headphones.

This ergonomic design ensures enduring comfort during extended listening sessions, crucial for professional use where long hours of wear are common. Additionally, the adjustable headband provides a secure fit without causing fatigue.
