哪位高人能给科普一下SILYNX C4OPS 这个东西

blackhawk1985

看了一些资料，也去了官网，官网介绍说是有降噪和辨别声音方向的功能，但是感觉这个C4OPS就是个多路信号传输器，没明白是怎么起到降噪和拾音功能的，耳机貌似也只是个耳塞啊？
下面是官网的资料，望高人指点：
Details The Micro C4OPS is a 20m immersible, in ear modular, smart, tactical hearing protection/hearing enhancement headset system.  The Micro C4OPS was designed to allow 5 x 5 communications in extreme noise environments and optimized for operations in air and maritime platforms.  The Micro C4OPS suite includes optional covert config, maritime config and earmuff config (see Headsets tab).
The Micro C4OPS is combat proven and widely used by the US Special Forces and tier one NATO Special Forces.
Features:•   Low profile, noise cancelling Ops Core Chinstrap Boom Mic with quick disconnect connector
•   Ops Core Chinstrap Boom Mic easily removed automatically allowing continuous operation of headset via in ear mic, for low vis operations
•   Helmet clip to secure to internal back strap of a MICH or Ops Core helmet
•   Micro Wireless PTT (MWPTT) with Picatinny Rail/Molle Attachment
•   Powered from MBITR/JEM and AN/PRC 152 side connectors

在军号论坛有个评测的帖子，不知道LZ看过没有，在评测区。

看过了，只讲了与对讲机的兼容性，没有它耳机降噪拾音的测试，我就想搞明白它一个小耳塞怎么降噪拾音的

原理极其简单,把传统耳机上的"拾音降噪"组件做到那个硕大的PTT一起了而已，耳机只是一个声音传输终端，包含的只是声音采集和发送功能，对声音进行处理的工作交给和PTT在一起的那些部件去完成了。

不知这东西能不能当手机的耳机用呢？有点浪费哈哈

手机又不必“降噪拾音”，再说山货早就出了能够手机用的外形类似的PTT了，装装样子也够了。

理論上是這樣升級，但實際上還會涉及到配件元件的定制和設計，在極緊湊的設計上的組裝，工藝加固，那個難度大呀。

对于工业技术如此发达的今天，这点设计和定制根本就不算什么难点了，又不是吧这些东西都集成到指甲那么小的地方，那个硕大的PTT的容积绰绰有余，技术亮点是不用耳机而用耳塞可以有效解决隐蔽问题和舒适性问题，别的真没什么。
