Because Logitech builds good speaker and I was looking for portable boxes without power supply and cables I slammed directly with this offer. Visually, the speakers are designed beautifully and the mobility is paramount. The supplied bag even has a reinforced outer wall is good and really what. The installation runs without problems (I only have to select in Winamp as the output device, the speakers and not my sound card from the notebook, Windows Media Player, the output is automatically set to the boxes and only here also operate the additional keys with me). For Sound: If you expect great music enjoyment here should not be fooled. A USB port provides happens to only 500 mA at 5 V and that is enough, of course not large sound pressure to generate (especially in the bass range). The music playback is a little disappointed me because I expected more fidelity from the speakers, the maximum volume is maxed out quickly, but in between for some music you get used to the sound. When video but look I was surprised how pleasant the other hand and according to the tone (quite Space Frame) is. I would advise anyone who has a desktop PC recommend 10 - spend 20 euros more and to buy a 2.1 system from Logitech, which brings across clearly frivolous music. However, if speakers for a notebook studied that are lightweight and durable, but also can not give large "soundscapes" that can access without any problems.
