Microsonic Earplugs Do we already have your impressions on file?:Yes Crossover: Integrated 4-way passive crossoverDescription Custom fit Musician Earplugs reduce all frequencies evenly so they avoid the skewed, muffled sound effects common to over the counter earplugs. The 15dB filter is a good balance between hearing protection and still feeling very live. The 25dB filter is for extremely loud environments. All filters are interchangeable. *please note 30 day money back guarantee does not apply to these Microsonic earplugs.
