此人體感應藍牙耳機，主要由QUALCOMM藍牙CSR8670晶片和SEMTECH公司的SX9310感測器晶片，兩部分組成的高端人體感應藍牙耳機。對比其他的藍牙耳機，額外具備“當來電 或 音樂時，耳機可以檢測是否為佩戴狀態，以決定語音 或 音樂是否轉回手機播放”高級功能。
SX9310 是電容比吸收率控制器（SAR）。擁有三個感應器件( CS0, CS1, CS2)，可以使用其三個中的兩個來精確地連接到SAR的智慧引擎,來做無生命的物體和人體區分。第三個感測器輸入可獨立用於標準電容傳感。I2C的通信介面，在檢測到接近物時由NIRQ腳輸出信號。SX9310包含一個片上的自校正控制器,定期進行敏感度調整以保持在寬溫度變化下的峰值性能，濕度和雜訊環境，提供簡化產品開發和提高性能。
