I have been using the auritech ear plugs for over 3 years now, which makes the high price much easier to swallow. Simply run them under the tap with some water and soap to clean them, and they are as good as new.
I find them really good, and they don't block out the noises you need to hear. Clever stuff (maybe witchcraft
They also come in a neat metal storage tube (which I attached to my keys) so I don't lose them... like Murf did!!!
