I picked up a pair of Etymotic GS-PRO plugs for Black Friday last year. They worked pretty well, but just not comfortable for more than a few stages without readjusting. However, I did just get custom ear molds made for them and now they work great. Well great until yesterday, l noticed one of them stopped working, so it's time to test their customer service department. https://www.etymotic.com/consumer/hearing-protection/gsp15.html Sent from my Nexus 7 using Tapatalk
