I have tried a lot of other ear plugs, but the wax ones suit me the best. Having said that, not all wax ear plugs are as effective as these. I have found others to be too sticky, but these are easy to insert and with practice at the initial moulding they stay in place very well. I use them for sleeping, almost every night, and would not be without them. Despite being described as single use, I rinse them in soapy water and reuse them for the best part of a week, with no ill effects.
