Message from the Founder


There are many devices we use today that perform incredible tasks to make our day-to-day life a little easier and more enjoyable. However, for reasons unknown to us, we still use off the shelf ear plugs, hearing aids, and ear buds. WHY!? Don't we all want the best possible sound in our lives at any given moment?

That's why The Listening Stack offers the largest selection of customized products to fit any lifestyle of sound. Whether you need custom ear plugs to get a good night's sleep, custom hearing aids to enhance your way of life, or custom in-ear monitors to deliver the best quality music, we have a solution for you!

Protect. Enhance. Enjoy!

Custom Ear Plugs & In-Ear Monitors

The biggest complaint we hear about over-the-counter ear protection products (earplugs) and in-ear monitors (custom earphones) is "They just don't fit comfortably." This is because ear canals are like people, they're all unique! At The Listening Stack all of our products are custom molded to your ear canal, improving the consistency of their seal and making them extremely comfortable to wear.

We believe that if your custom products are easy to use, work well, and fit comfortably, then you're much more likely to wear them! And when you're protecting your ears, enhancing your music, or improving your comfort, life is just that much better!
