The kit consists of a pair of speakers (one on the right incorporates a potentiometer - on / off, volume - and includes all the connectors), transformer and mini jack audio cable to connect the audio source to the system. Note that there is no subwoofer, but it is not at all annoying to listen. Moreover, it is often better to do without a subwoofer that have poor quality. Heavy bass lovers (for games, for example) will still unsatisfied.
The finish is good, but the appearance of the speakers is terribly banal. This sobriety is obviously a matter of taste. Compactness is an undeniable advantage of this kit (about 20 cm high and 15 deep and 8 cm wide.)
The choice of a specific connector for the left speaker is a bad idea: the cable is rather short (less than 2 m, to be connected to the other speaker) and it will be impossible to get an extension. The power cable is not very long either.
The right speaker can connect two different audio sources (mini jack plugs) and also has a headphone output.
Regarding sound quality, the results are really excellent for small speakers. The music is very pleasant to listen to, it's also true for movies. Given the quality and achievement, we would have better appreciated the bass can go lower without cabinet ... it's impossible. But the result is an excellent level, many other speakers of the same kind are much less well. The whole can achieve a very respectable sound level.
Remains a fairly high price positioning. At this rate, we can find decent kits 2.1 or 5.1 "first prize" ... of uncertain quality audio.
