These are the ideal solution for laptop users, due to their portability and usb power.
Sound quality is reasonable as you'd expect at this price point - although volume is quite impressive there is a little bit of tinny distortion when turned right up. However it is perfectly acceptable for music and general web use (youtube etc)
The build quality is excellent, the speakers are pleasingly solid and they look impressive with a black gloss finish.
With just a usb connection (no mains power) I expected something of a battery drain on a laptop, but they didn't cause anything notable on this front.
So, if you're after a good value set of speakers to chuck in the laptop bag for holiday or anywhere else on-the-go, then these are a decent option.
