From around 150 Hz upwards and at low volume it sounds quite pleasant, with a slight tendency towards sharpness and harshness, the highs do not quite up to the threshold of hearing and radiate very directed, with side earhook they disappear quickly. In the very near distance and listening on a tabletop, or even better put in a corner of the room, the bass get a little more body, but of course are not enough in the deep cellar because the physics is unfortunately insurmountable limit. Snare and tom-toms are still beautiful audible, but bass drum and bass guitar are more than erahn.- audible. Human voices are discolored slightly nasal, but have enough brand recognition.
Until about 1 m distance is even a little stereo effect audible beyond the Stereobox but quickly due to their minimal stereo base for Mono Speaker. The achievable volume is quite impressive but, of course, limited to the small speaker and goes on noisy end smoothly into more and more distortion.
Better than my portable speakers it is always, for the party sound he is of course overwhelmed and not think so.
Very good, I like that thanks to USB Audio, the speakers connected with just one USB cable to the notebook both plays and loads.
Battery life is very good with several hours non-stop sound at low volume.
Etc. A transport bag supplied would have been nice since the lightweight speaker due to its smallness like mitmöchte, but this will not be scratched in your pocket or backpack.
Conclusion: Small, handy and conveniently powered stereo speakers, the sound quite a bit taller than he is.
