Know before you buy
These are custom-molded in-ear monitors designed specifically for professional stage use. Unlike universal-fit earbuds, they are crafted to the exact shape of your ear canal to provide a secure fit and superior acoustic isolation.
The custom-fitted design provides 26dB of passive noise isolation. This is significant enough to block out the majority of ambient stage noise, allowing you to monitor your mix at safer volume levels.
With an impedance of 37.5Ω and a sensitivity of 105dB, these monitors are efficient enough to be driven by most professional audio interfaces, mixers, and high-quality portable players without requiring a dedicated external amplifier.
This configuration splits the audio signal into four distinct frequency bands, assigning specific drivers to handle lows, mids, and highs. This prevents the drivers from overlapping, which results in much higher clarity and detail across the entire 5Hz to 22kHz range.
Yes, the included cable is built with 168 strands of silver-plated copper litz wire and features a pull strength of 120 Newtons. It is specifically engineered to be sweat-resistant and withstand the physical demands of live performances.
Because these are custom-molded, you will need to visit an audiologist to have professional impressions taken of your ear canals. These impressions are then sent to Ultimate Ears to create your unique, personalized shells.
