See What Others Are Saying

  • It really was quite impressive

    They worked extremely well, and I was not bothered by any ambient noises.  I move around a bit when I sleep; they stayed firmly inserted and did not cause any discomfort.

    The fit and comfort are a direct result of their innovative custom photo-measurement software and manufacturing process. It really was quite impressive.

  • A fantastic product and process

    As someone with ear sensitivity, I could never have custom molds made; the process would cause discomfort. Thanks to Fen X, I now have several custom pairs for a number of activities: competitive shooting, hunting, sleeping, etc.

    I keep a set in my car and at work, just in case I need a pair. What a fantastic product and process!

  • No more tossing and turning

    My husband and I recently got these, and we’re honestly wondering why we didn’t do this sooner. The process of scanning with my phone was a lot of fun and they fit perfectly.

    They block out noise but let you hear the things you need to. No more tossing and turning, just uninterrupted sleep and happier mornings.

  • These ear plugs are amazing

    I work in the construction field and have used these on the jobsite many times. When you work with nail guns, saws and hammers, etc., it makes the jobsite comfortable to work on.

    I was still able to hear my coworker, which most plugs don’t allow. I would definitely recommend to anyone in the trades – these earplugs are amazing!

  • I'm glad to have them

    These earplugs fit really well, and I could feel the positive impact of sound reduction immediately. As I age, I'm very in-tune to the importance of being cautious with my ears in loud environments.

    These are easy to carry with me in my purse, and I'm glad to have them available at a moment's notice.

  • Fast, easy, and non-invasive

    The scan on my ears was fast, easy, and totally non-invasive – the custom plugs fit perfectly. I keep them handy in my purse, it’s so easy to just slip them in.

    Very comfortable and you can barely see them. I wear them in the office whenever I need to concentrate.

  • Love them

    I swim a mile in open water (weather permitting) or pool a mile 3 to 4 times a week and have been using Fen X ear plugs for about 3 months and love them. I can hear with them in and no water is getting in my ears.

  • Highly recommend

    I use these ear plugs for Target practice and when I am duck hunting and I can honestly say, I have never owned a better pair of hearing protection.

    At the range it’s gets loud and I can still hear my friends talking. I highly recommend them!

  • Makes the riding experience better

    As a motorcyclist, these earplugs blocked out wind and other loud, damaging sounds without making everything you want to hear sound muffled or distorted. They're comfortable to wear and are custom molded to your ears.

    They make it easy to do the right thing and protect your hearing while making the riding experience better, not worse.

The Painful Truth

There are a high concentration of sensory nerve endings in the ear canal making them very sensitive to pressure. At each curve of the ear, a standard earplug is forced to bend, creating pain points.


Fen X Custom plugs are shaped like your ear canal, eliminating the pain.
