These Ergo fit headphones are extremely comfortable. They come with three different sized ear buds, but I found the size which came already fitted were perfect for my ears - not too big, not too small. The headphones themselves are light and come with a decent length cable, though it is quite thin, so is prone to tangling quite easily.
Sound quality is very pleasing. It's a tad weighted towards bass and can sound a little 'muddy' depending on the type of music you listen to, but is certainly not disappointing.
These are as good as any other headphones under a tenner I've tried. As always though, the real test will be their durability - anything which lasts 6 months is alright by me!
