My audio output on the laptop was broken, so I was looking for a new solution to listen to music through external speakers (great sound system). And I have come to this simple USB solution. The sound is great, the service also. If desired to change between sound through USB port or by the internal laptop speakers a little enabling and disabling the audio controller ranges in the sound options.
The only drawback, the small device is very poorly compacted. The USB interface is fast easy and the housing starts early to wiggle, but this does not change the functionality.
