Please do not go through support as per usual for any requests pertaining to the UERM, but rather direct all questions and inquiries to Daniel.Liu@massdrop.com.

As CIEMs are a time-intensive product to make in bulk, expect longer lead times. Updates following the end of the drop will only occur: When ear impressions are shipped to the manufacturer and when the final product is shipping out to members.

99 Problems But Fit Ain't One

Do the shells of universal IEMs feel strange in your ears? Are foam and silicone tips just not doing it for comfort? Make your worries about fit and comfort things of the past with Ultimate Ears Pro. The UE Reference Monitor is molded exactly to your ear shape, providing you the noise isolation and accurate presentation required by professionals and enjoyed by serious audio enthusiasts.

At checkout, choose your cable and case of choice, as well as your name engraving. The faceplate is restricted to the stock UE and Capitol logos.

To individualize the UE Pro IEM to your ears, you will need to visit an audiologist for ear impressions. Visit the UE Pro preferred audiologist map to find one near you. We will contact you after the drop to coordinate sending the impressions to the manufacturer. You are responsible for the shipping of impressions to Massdrop.

Studio Sound

Developed in tandem with the engineers at Capitol Studios, these reference monitors combine the Ultimate Ears Pro signature sound with a flat frequency response curve ideal for recording, mixing, and mastering. Thanks to the noise isolating construction and three balanced armature drivers, the outside environment never intrudes and the presentation is always upfront and powerful. As passive crossover technology tunes and separates the specific frequencies, you get clarity and detail across authentic highs, clean mids, and visceral lows.

Hot Acrylics

Digitally hand crafted and 3D printed with 100% acrylic housing, the UE Reference Monitor is durable, lightweight, and effortlessly stylish. The opaque black faceplate, clear back housing, and subtle logos add just the right amount of aesthetics and the overall package is small and light enough to take with you everywhere you go. Rounded out with a low distortion cable, engraved carrying case, and cleaning tool, the Ultimate Ears Reference IEM tailors your music experience for maximum comfort and pleasure.
