随时随地享受监听和混音的极致体验

NDH 20采用新设计的、带有较高高斯值钕磁铁的驱动器（38毫米/1.5英寸），以确保高灵敏度和最小的失真，从而让用户只听到纯音频信号，而没有不必要的着色。机械结构也符合最高标准。可调头带由柔性钢制成，耳罩由轻质铝合金加工而成。为了便于随身携带，耳机可以折叠起来，并可放置在随附的软布袋中。还附赠两条可拆卸耳机线（一条直线，一条盘绕线）和一个6.3毫米（1/4英寸）的适配器。

应用

NDH 20适用于所有需要高度隔音效果的应用，例如音乐家和工程师在室内跟踪监听任务以及FOH (调音师现场)工作。它也是进行重要聆听的绝佳选择，不受外界干扰，反之亦然——不会因声音泄漏而对附近的人造成干扰。由于其扩展频率响应范围在5 Hz至30 kHz之间，NDH 20非常适合检查音频频段的上下限。

与其它大多数封闭式耳机不同，诺音曼 NDH 20也适用于混音。异常均匀的频率响应和自然的立体声图像让用户可以放心地进行混音，并确保兼容所有播放系统。因此，NDH 20是外出工作时移动办公不可或缺的工具。当然，它也是音响爱好者享受音乐娱乐的绝佳耳机。
