Unfortunately, the sound quality is really quite modest: deep bass does not exist, for the upper bass roars mightily. The much too low altitudes can bring with the built treble controls to a reasonable level, but to wean the speaker the roar, you have the bass rausdrehen very far. The sound is a little bit when the speaker stood in a bucket.
The electronics is great: Two ports, one of which is analog RCA, the other analog jack or digital optical (TOSLINK) or electrical (coaxial). Both ports can be separately regulated via two volume controls on the front, which is not switched between the inputs, but always are both active. Perfect to z. B. to listen to music from an input, but output the sound from the PC via these speakers. Headphone output is attending, and controls for bass and treble, the incredibly nonlinear, however, are (and absolutely necessary to make it sound the speakers at least halfway acceptable). Absolutely not hear noise and no humming, no signal.
Processing is quite good, the plastic smell is not so bad. A cable for connecting both speakers is, however well hidden in the styrofoam packing material. Power cable is also included, otherwise nothing.
Conclusion: These speakers can not match the sound forth with HiFi speakers; for the price that would have been a sensation. As computer boxes they are certainly quite good, if you have the space, no real bass needs and no demands on the hi-fi sound has. Here the two mixbaren inputs and the digital input play IMHO its strengths. To get an mp3 player loud, they are certainly not wrong; the recoverable volume is well above room volume. For me, they have found a place in the kitchen, because they mean quite high demands on the computer does not have justice - they are perfect for this purpose: inexpensive and loud.
Despite the practical electronics and the recoverable volume only three stars because they can not quite convince in the main discipline, the sound.
