缺點：
Disadvantages:
1、由于jbl音響的配置比較高，自然在價位方面也相對較高，這對于一般的用戶來說還是有點難以接受。
1. As the configuration of JBL audio is relatively high, the price is also relatively high, which is still a bit difficult for ordinary users to accept.
2、jbl音響有些款型的體積偏大，聲音開到足夠大的時候感覺三頻不均衡，高頻略有破音，低頻下不去。
2. Some models of JBL sound are bulky. When the sound is large enough, I feel that the three frequencies are not balanced. The high frequency is slightly broken, but the low frequency is not.
3、jbl音響電源管理模式有問題，當聲音信號小時，音響會自動關閉。當在筆記本上盡管實際音量很大，但播放一段時間后音響會自動關閉。當在臺式機上正常，但一旦把音量條拖小，音響就會自動關閉。
3. There is something wrong with JBL audio power management mode. When the sound signal is small, the audio will turn off automatically. Although the actual volume is very high on the notebook, the audio will automatically turn off after playing for a period of time. When it's normal on the desktop, but once you turn down the volume bar, the stereo will turn off automatically.
