"Simply moisten the tip before insertion - perfect!"4.5 starson by ronrpeterson
Pros: Price, performance, value.
Cons: Durability could be better, pulled cord out on several pairs when at work.
Summary: If you moisten the tip before inserting them in your ear it makes a perfect seal, eliminating at least 25% more noise and creating a perfect reflex chamber in your ear. The difference between moistening and not has to be heard to be believed. I buy these things half-dozen at a time, give them away to friends and to replace them when cord gets tangled and breaks-pulled out.
