I was looking for a few different earplugs to try out at live music events (listening and performing) and found these. At £2.49 for 10 pairs I thought they were worth a go. A good fit on me, although everyone's ears are different, but at this price you can afford to try them out. They seem to block out a lot of noise, possibly too much for listening to music! Although disposable, you should be able to use them several times before they lose springiness (or you drop them in the mud at a festival!). Major plus points are well written fitting instructions and very quick delivery (they came the next day, although the supplier only specifies 3-5 days). I have bought much more expensive ones at camping shops (about a fiver for three pairs) and these ones are better.
