Unverified报警灵敏度与误报率是核心矛盾：灵敏度调高会把久坐不动、深睡浅呼吸误判为异常，调低则可能漏报真实跌倒；选购应关注是否支持多级灵敏度可调+静止时长自定义阈值，而非追求单一高灵敏79% similarUnverified震感相比欧乐B旋转式或飞利浦高频声波款偏柔和，追求强烈清洁反馈感的用户可能觉得力度不够79% similarUnverified灵敏度越高越容易推响但通常动态压缩感越强、失真控制越弱；追求高解析监听宁选低灵敏度配大功率功放，追求省事简单选高灵敏度77% similarUnverified静音效果越好（实心硅胶）触感反馈越单一，趣味性和解压"爽感"越弱；带声音和按键的产品刺激更强但扰民，需按场景取舍76% similarUnverified指向性越锐利（超心形/枪式）离轴抑制越强、抗环境噪音越好，但对拾音角度要求越严格，人一偏头声音就变小变闷；单人固定位置选锐利指向，走动多选心形容错更高76% similar
