well headroom

基本解釋

I can push the drivers to high levels of volume without distortion, so safe listening volumes are well within the headroom of the drivers.
我能將音量開得特大而耳塞卻不會聽出失真，而且在安全的聽音音量下單元也能良好地發(fā)揮應(yīng)有的水準(zhǔn)。
In any case, it shouldn't matter to most people wanting a card like this, knowing full well that a quality PSU with plenty of headroom makes for a much more stable gaming rig.
在任何情況下，這一問題竝不應(yīng)該對大多數(shù)人希望這樣的卡，竝且充分認識到一個足夠的空間使優(yōu)質(zhì)電源爲(wèi)一個更加穩(wěn)定的遊戯鑽機。
