FitKit Walkthrough


Ultimate Ears headphones are your ticket to a rich and varied world of sound and getting them is easily done through a few exciting and simple steps.

Where Do I Start?

The process begins at the Ultimate Ears CSX site where you select from four CSX models. Each model is equipped with high-performing speakers containing a range of two to six balanced armatures drivers, an award-winning cable system and a custom tuned sound. If you are unsure about which model is right for you, Ultimate Ears has designed a short set of questions about your musical preferences to introduce you to your perfect sound. Once you’ve identified the model that matches your needs, you can choose from a variety of faceplates or completely customize your own from color and material down to your initials.

Taking the customization further, your earphones are modeled after your one-of-a-kind earprint which is captured in a specialized ear impression. For the CSX series, impressions are created using the patented FitKit developed by Ultimate Ears to increase accessibility to the amazing sound revered by music professionals and music lovers alike. A process that was once limited to the office of an audiologist, the FitKit uses unique technology to make an impression in minutes and from the comfort of home. After placing your order, a Fitkit is shipped with each piece of equipment conveniently packed in a small box.

Set Up Your Fit Kit

When you open your FitKit, you’ll be prompted to download the companion app which will guide you step-by-step through the entire process. The app includes easy to follow instructions and uses the incredible FitKit technology to trigger the impression process. It’s helpful and fun to find a friend or family member to engage in the process as you’ll need someone to take pictures of your ears with the impressions in place.

Create Your Impressions

Inside the box are molding tips that will fit the majority of ear sizes. The app will instruct you to try on the molds and direct you to your ideal fit. Every person’s ears are completely unique to them and even differ from left to right. In some cases, you may require a large molding tip on one side and a small on the other. Should you be concerned that you’ll need an even smaller size, Ultimate Ears can provide an additional molding tip to accommodate even the smallest of ears.

Easy App Guided Process

When you determine the right size tips, you’ll attach them to the fitting device which wirelessly connects to the app. You’ll be instructed to carefully reinsert the molds which go in easily. Before the impressions are made the app will prompt you to check that everything is in place prior to hitting the “start” button. Now your impressions are underway and a timer appears to count down the 60 seconds to completion. In exactly a minute, the molding tips heat up creating a warm sensation as they conform to the shape of your inner ear. As they comfortably harden into place, your ear print is locked in. The fitting device communicates with the app throughout the entire process ensuring accuracy at every stage.

When you take out the molds, you’ll hear and see the difference. As the molds adjust during the impression process, ambient sounds are reduced confirming that the process has created an accurate fit. Before taking them out, have your friend or family member take pictures that will be used by Ultimate Ears technicians to enhance quality and fit. Once removed, you may notice ridges or grooves have formed reflecting your inner ear shape.

Send Your Molds Back To Us

With the process completed you’re ready to return your impressions and the FitKit with the return shipping label provided. When they arrive at the facility, they’re 3D scanned to create a precision shell and an unparalleled custom fit.
