I have this usb headset: http://www.plantronics.com/us/product/audio-478

With the level turned all the way up in System Preferences, it's not loud enough for some uses.

Is there a way to increase this level?

You may use volume booster software like



In iTunes Library select media with low volume and press cmd+i . Go to Options and make Volume Adjustments.


VLC allow you to increase volume to 200% by simply scrolling all the way up.
