DUBS Acoustic FiltersTM use Dynamic Attenuation, an intricate mechanical process that filters sound. While traditional earplugs distort and muffle, DUBS engineers developed a proprietary combination of high- and low-pass filters that allow DUBS to reduce volume while preserving the proper balance and clarity of the audio you hear. Instead of blocking all noise, these advanced earplugs are pre-tuned to target specific frequencies, allowing you to hear the world the way it was meant to be heard. Built to last. Designed to be worn. DUBS are constructed using premium materials–including high-strength plastics, stainless steel, polymer foams and silicones–to create a durable product that can be worn over and over, every day. Unlike awkward foam earplugs, the unique form factor of DUBS Acoustic Filters allows them to be worn comfortably and to sit flush against your ear. They’re also reusable, and come with a convenient portable case that you can carry around anywhere you go. Hear the world better–order your DUBS Acoustic Filters from Brookstone today!
