    ER 6 (#186)
    ER 6 Isolator Earphones are in-the-ear, high-fidelity transducers
    developed to combine flat frequency response. We combine them with
    custom db Blocker experience to provide isolation from external noise.
    When properly sealed in the ears, these earphones provide 15-20 dB of
    external noise exclusion. This allows the listener to hear the full dynamic
    range of recordings at lower reproduction levels.
        • Perfect for travel and commuting – plug into any audio source
            (airplanes, laptop, computers, CD, DVD, MP3, Motorcycle)
        • Smooth, extended high-frequency response
        • Excellent bass
        • Requires custom earpiece for maximum effect (#2700)

           ER 4
           ER-4S (stereo #171)) earphones have a flat frequency
           response that is the closest to a perfect fidelity response of any
           in-the-ear earphones, and equal to that of electrostatic
           earphones that cost thousands of dollars. Designed for home
           stereo systems or as monitors, these earphones can be used with
           a headphone amplifier when using low-power portable devices.

    Sweet Tones                       (#3200, #3000, #4000)
    Sweet Tones Musicians hearing protection replicates the natural
    response of the ear canal so the sound heard with these earplugs
    has the same quality as the original, just quieter.
    Musicians practice and perform in a variety of different settings
    and they are exposed to high levels of sound, sometimes for
    long periods. They require different amounts of protection
    depending on the sound levels they encounter during rehearsals
    and performances, therefore musician plugs are available in
    different levels of sound reduction:

    ER-9: Flat 9 dB sound reduction through the mid-range. Same high frequency
    protection as the ER-15.

    ER-15: Provides uniform 15 dB sound reduction across all frequencies.

    ER-25: Provides 25 dB of relatively flat sound reduction across all frequencies.
    Important: Sweet Tone hearing protectors require custom earmolds. Impressions
    must be taken to create these earplugs.
