The notebook is usually very bad, but can improve a lot with this portable USB sound box iKanoo.
Along with the box we also have a support for laptop screen and a vertical support. In addition to the instruction manual.
The box is very pretty and was designed to be placed on top of the monitor.
The back is plastic. There is no audio cables, the box connects only via a USB sound card.
You can also put the box in a vertical support.
I really liked the product. Pity that works only on the PC because it was designed to be used as a sound card. Even so, worth it especially for notebooks. I leave below link to DealExtreme:
