Unverified防水等级与音质权衡：高防水机型往往采用密封结构，会牺牲部分音质通透度，纯家用不接触水的场景不必为高防水付费90% similarUnverified防水等级越高机身密封越好，但会牺牲音质通透度（防水膜阻挡声音）和充电便利（需胶塞遮挡接口）；纯室内用户无需追求高防水89% similarUnverified防水与音质存在矛盾：高防水需密封网罩和防水膜覆盖发声单元，会削弱高频通透度，纯追求Hi-Fi音质者浴室场景难两全，应优先防水88% similarUnverified防水等级越高机身密封越严，往往牺牲音质表现（防水膜阻碍振膜发声），追求Hi-Fi音质与高防水难以兼得，泳池派对可接受音质折中86% similarUnverified防水性能较好但并非完全密封设计，长期暴露在车底或无遮挡位置仍可能因积水导致音质下降或锈蚀，建议安装时喇叭口朝下以利排水84% similar
