How many speaker drivers do headphones need to deliver great stereo sound? One for each earphone? two? six? Knowles has teamed up with Ultimate Ears Pro to release the UE Premier in-ear monitors, which, frankly, have 21 drivers per headphone.
Originally unveiled in April at the 2023 NAMM show at the Anaheim Convention Center in California, the Ultimate Ears Pro, “the most powerful, nuanced and versatile in-ear monitor ever made,” is said to set a new standard for audio excellence. The gold standard, it’s now ready for performance musicians, studio producers, demanding audiophiles, and more.
The UE Premier IEM is reportedly the industry’s first headphone to feature 21 drivers per headphone in a five-way passive crossover design, including eight Knowles dual-diaphragm balanced armature receivers to deliver “warm, natural sound , along with four Knowles super tweeters for a “warm, natural sound”. Extend the top end with UE Pro’s True Tone Plus drivers.
Philippe Depallens, Vice President and General Manager of UE Pro, said: “The dual-diaphragm and supertweeter receivers allowed us to define new dimensions of sound, achieving the best possible frequency response and acoustic resonance for airy, rich and versatile sound. Listening experience.”
UE Pro says each driver is individually tuned to accurately reproduce different frequency bands, as low as 5 Hz and as high as 40 kHz. To ensure a secure fit and optimal passive isolation, buyers are required to submit an audiologist-created impression or obtain a digital ear scan so that the UE Pro can precisely 3D print a custom shell to individual requirements.
The UE Premier in-ear monitors are available now in a variety of colors for $2,999.
