If you don't mind spending $40, it appears the earasers are among the best on the market. I've heard some horror stories of Dubs brand ear plugs falling apart in people ears resulting in doctors visits. Erasers come in many different sizes. Source: did hella googling and it appears these have good sound and build quality comparable to custom ear plugs. If you are spending $15-20 on a crap pair, might as well fork out the extra $20 and get a lasting, quality pair IMO.
