Stealth Sonics have gathered research from a vast network of audiologists and breakthroughs in the aerospace industry to create a new range of IEMs which engineer ultra-precise, second-bend ear canal impressions to position the earpiece within just a couple of millimeters of the eardrum. The advantage of this is the ability to listen at a lower, safer SPL; going as close to the eardrum as possible ‘reduces uncontrollable acoustic gain along the ear canal and therefore lends itself to higher fidelity sound’.
