各種事物都可能對藍牙通訊造成影響，導致藍牙耳機出現聲音或雜訊問題。請依照以下各個可能情況的對應解決方法進行操作：
在混合多種無線電波使用的地點或環境時，例如Wi-Fi 路由器、個人電腦、微波爐、冰箱等附近，一旦遠離則可避免發生無線電波干擾可能導致之雜訊 ,如果使用具有降噪功能的耳機，請關閉降噪功能。
使用耳機的位置遠離了播放器，例如：在另一個房間。則會影響藍牙接收強度, 請盡可能讓藍牙耳機或喇叭靠近藍牙播放器。
透過網際網路串流播放音樂或音訊資料 ： 串流播放的音樂 (音訊資料) 會傳輸至藍牙耳機，因此聲音會受到網際網路的通訊條件影響。此外，播放容量較大的音樂或音訊資料也可能會對播放流暢度造成影響。
在許多應用程式同時執行時使用藍牙功能時可能會造成聲音中斷或雜訊，請關閉播放裝置上其他應用程式以減輕負載即可。
若仍有問題，請依照這些步驟進行操作：
兩邊耳機長按5秒關閉耳機，在長按3秒重新啟動耳機。
在連線裝置上（例如手機）重新進行藍牙連線。
注意：如需重新設定已連線耳機的相關詳細資訊，請參閱重新設定與配對。
如果耳機剩餘的電量不足，請先將充電盒充電，然後再進行上面的程序。
