Ok for the faint sound sources. But: no sound profit

One more gain in sound quality does not give the headphone amplifier of Creative. On the contrary, I had the impression that the bass a little more volume and less precision was available.
With very weak, portable sound sources, the small amplifiers eigenet naturally good. Especially when you want to listen to music with higher resistance headphones. It is also good that you can use it as an external sound card for the netbook or laptop. For traveling it is recommended conditionally, because the whole tangling disruptive.

Solely because of the sound profit, the mini-amplifier is not recommended. For this purpose we have to turn deeper into their pockets. As a low-cost solution with acceptable sound amplifier for mobile PC, it is still recommended.
