Pros: + The sound is good to listen quietly to music, Skype, and YouTube movies: the sound is clear and nice. + The quality is rather good, low bass but they spend a little: they are not completely stifled. + No parasites. + USB Power: it releases an electrical outlet and it avoids the transformer.
Cons: - The cable that connects the two speakers is about 70 cm so we can not really spacing (1 star less) - The length of the audio cable jack is also relatively short.
