Custom earplugs are a great way to protect your hearing in loud environments. Constructed using 3D-Fit technology, these custom earplugs fit more comfortably than universal sets, making them more enjoyable to wear longer. Made with hypoallergenic, hard acrylic, each earplug is built for longevity and durability. And their low-profile design makes them subtle to wear out and about.Our earplugs are designed to fit our apex modules or our solid noise isolating plugs. Apex comes in -15dB or -20dB modules and uses pneumatically interactive vents to alleviate stress on the eardrum created by the occlusion effect. This ventilation also provides a high fidelity listening experience for concerts or other loud venues.Our solid plugs do not feature our apex technology but offer up to -26dB of isolation. The solid plug is designed to be the same size and shape as our apex modules, so listeners can swap out the units for different levels of isolation in different environments.Custom Earplugs Come With: Our zipper case A cleaning tool A discreet, removable lanyard Your choice of mX, m15, m20 or m26 Solid plugsBuild time: 1-2 Weeks
