When BEANS PRO 2 activates the ANC (Active Noise Cancellation) mode, it will assign part of the low frequency sound into pin noise frequencies.
So if you want to experience the best sound quality of BEANS PRO 2, we recommend switching to "Ambient Sound Mode Off"
當BEANS PRO 2 啟動 ANC ( 主動降噪)模式的時候 , 將會分配部份低頻聲音轉換成銷噪音頻率。
所以如果想體驗 BEANS PRO 2 的最佳音質,我們建議轉換為"環境聲音模式關閉"
