Summary: The sound from these things is nice, but the only input is USB which means they're only useful when attached to a computer. There isn't a separate 3.5mm input for an MP3 player. They're supposedly portable, but they're a bit heavy to be lugged about all the time. The trade-off is that their weight helps produce the nice sound but also makes me want to leave them on a desk in a semi-permanent installation, but I've already got an adequate 2.1 speaker setup and.
Summary: Admittedly, it is quite loud considering that it is powered via the USB 2.0 port. However, it sounds quite mediocre to bad given its original price tag. For the £20 I paid, they are not brilliant either, just a little above average. If portability is not a issue, you are better off buying traditionally speakers - my old Cambridge Audio 5.1 can easily blow they away.

Summary: Happy considering that I paid £17.99 for these as IMHO that is a fair price for them, but had I paid any more than that I would have been returning them for a refund. The quality is excellent, but I find that they are nowhere near 30W, more like 2w to be honest.I was impressed that they worked with an android Tablet too but again nowhere near 30W.
Summary: I like the speakers: they look and feel great, they're well made, heavy, and unobtrusive on the desk. The sound is also excellent. BUT, if and when my PC goes into sleep mode, the speakers no longer work afterwards. A re-boot of the PC is required to make them work again, which is a hassle. Having read up on this on the net it seems others have reported this problem too. The question is, can you live with that?
Summary: Bought as a gift for someone, they look good, feel heavy, just lack a bit of oomph so left me feeling as as if I had been a bit mean! I have small USB speakers myself which were cheap and I have had for years, and whilst they had won no awards, they have a lot more substance. Yes they have great clarity, but overall a little underwhelming.
Summary: These are excellent travel speakers, presented very nicely in a smart travelling bag, they are obviously soundly built with quality linking cables. On my desktop Mac they produced a very clear sound, picking up a great deal of detail that I don't hear normally, making me realise that I really do need a pair of quality desktop speakers. Just not these.
