Discreet and ideal for musicians.  These custom made high-fidelity musician ear plugs replicate the natural response of the ear canal so that the sound you hear with them has the same high-fidelity quality, just at a safer level.  Filters are interchangeable and selection will depend on acoustic and instrumental factors.  Music teachers, band teachers and students, and concert attendees will also benefit from the flat attenuation when the need to hear accurately in high-noise environments is expected.
