Why Musicians Earplugs?
Regular earplugs are great for protecting your ears from loud noises, however an uneven noise attenuation makes it unsuitable for musicians. Musicians are often exposed to high level of sounds, putting their own hearing in danger if not protected. Jomo Audio's Musician's earplugs comes fitted with a filter that evenly reduces the sound entering your ears.

3 Different attenuation levels for different users (Note: Attenuation level filter cannot be swapped)

Suitable for:
9dB Strings, Vocalists, Acoustic Guitar users
15dB All users
25dB Brass, percussion, Amplified Instruments users
