  • Unequaled Performance

    The EarPeace custom fit acoustic filters provide the flattest response of any hearing protection. These ear plugs deliver an accurate representation for anyone that requires complete fidelity from their ear plugs. Originally designed and perfected for musicians and vocalists, EarPeace custom fit is now retooled with the wearer in mind. For starters, it’s smaller than many competing filters which means it can fit into smaller ears without any protrusion which is great for both comfort and style. The filters can also be swapped to any other level as your environment demands, giving you complete control over your protection with just a single set of custom molds. In addition, EarPeace custom fit are water resistant so they can be used outside or in high moisture environments and can withstand perspiration without it damaging the filter membrane.

    We solved the “occlusion effect”

    Trying to create a natural sounding earplug is hard. Sounds that you create are carried to your ear canal through bone-conducted vibrations along the side of the head. These vibrations normally escape through the open ear canal so they not “heard”. When you block off your ear canal, the sound of your own voice / what you ‘hear’ is amplified inside your head because the vibrations don’t escape. Audiologists call this the ‘the occlusion effect’. A large amount of occlusion can be eliminated by ensuring that the ear plug sits deep enough in the ear canal so the vibrations hit the plug rather than entering the canal at all. EarPeace custom fit goes a step further and are vented to allow sound to pass both ways, delivering a natural sound experience.

  • Fitting Guide

    Each of your hearing protectors is marked with red or blue detail. The EarPeace with red detail fits the right ear and the one with blue detail fits the left ear. Hold the hearing protector as in Figure 1 and insert into the ear canal twisting it backwards while applying slight pressure as in Figures 2 & 3. Press the protector until it fits comfortably in your ear as in Figure 4.

    Where your hearing protectors have a grip, hold the grip when inserting the earpieces.

    To remove, grip the hearing protectors and twist in a forward motion while pulling gently from the ear. NEVER remove by pulling on the (optional) connection cord or the cable (Communicator variant only).

    A tube of comfort cream is provided which can help with insertion, by spreading a small amount on the tip of the earpiece that fits into the ear canal. Pay attention not to get cream into the sound duct.

    Care and Maintenance of your Hearing Protectors

    It is important that you read these notes to ensure longevity of your custom hearing protectors. Failure to care for your hearing protectors in accordance with the instructions could severely affect their performance.

    Use a moist cloth or sterile wipe to clean the silicone moulds. Visually inspect the sound ducts on each earpiece to check that no wax, skin debris or dirt has penetrated. Use the wire loop pick provided to carefully remove any matter. Always return to the carry pouch when not in use. Keep away from moisture and heat or direct sunlight. DO NOT immerse the filters in any liquid. The filters can be removed by gently squeezing the mould around the filter until it ‘pops’ out allowing the moulds to be thoroughly cleaned. After cleaning, ensure that the filter socket is completely dry before replacing the filter.

    If your hearing protectors incorporate wired components do not immerse your earpieces in any liquid.
