Unverified入耳硅胶塞尺寸是佩戴与降噪的关键，配件含多组耳塞（S/M/L）的机型更易找到密封贴合，密封不好会同时导致漏音和降噪失效90% similarUnverified入耳式降噪耳机对耳道密封度依赖极高，耳塞尺寸不匹配会导致降噪和低频严重损失，购买后必须试戴至少3种硅胶套并做贴合测试88% similarUnverified隔音效果主要由耳塞硅胶套的贴合度决定而非价格，硅胶套需选对尺寸（S/M/L），换用记忆海绵套可比标配硅胶套提升5-10dB隔音，通勤/地铁场景优先关注被动隔音而非主动降噪88% similarUnverified降噪效果与佩戴密封性强相关：入耳式Pro 2需用配套三/四种硅胶耳塞做密封性测试选对尺寸，尺寸不对降噪和低音都会大幅衰减87% similar
