耳机有多种形式和功能。耳机的主要功能是提供高质量的立体声音乐和声音，但最先进的耳机还包括许多其他功能，包括用于语音捕获和噪声消除的麦克风、声音处理、用于音频播放和呼叫处理的耳机线控、无线连接和无线充电。骨振动传感与MEMS麦克风的高质量语音捕获和优化的信号处理相结合，使微型入耳式装置实现前所未有的语音质量。

ST提供的一系列产品可以提高耳机的设计质量。主要产品包括具有高动态范围的低功耗模拟和多模态数字MEMS麦克风、运动和振动捕捉传感器、用于控制和声音处理的低功耗微控制器、超低功耗蓝牙连接、以及音频放大器。我们提供的无线电池充电系统解决方案简化了设计，占用空间小，确保安全可靠地进行有效充电。
