On the plus side, it gave me good sound while it worked. And at only £0.40 with free shipping, the price was more than right.
On the not-so-positive side, it stopped working after 6 months. No matter how I adjust the cable, I just get muffled, bass-only sounds so this is clearly no good. The only negative is that the cable is fairly short, so I have to keep my speakers close to the sound source, usually my laptop.
Still, if I can get good sound for £0.80 a year, that's something to celebrate, hence the average review.
