Monitor your performance with 64 Audio's professional universal in-ear monitors (UIEM) specifically designed for musicians and live music professionals. Whether you're just getting into monitoring with in-ears, not ready for customs, need a backup set, or simply prefer generic fitting products Aspire 4 offers best-in-class sound and ergonomics.


World Class Sound

With live music at the forefront of our tuning criteria do we make a highly accurate unforgiving studio monitor or a contoured device that helps musicians hear themselves more effectively? As with many of our monitoring tools the answer is somewhere in the middle. Huge bass that can reproduce some of the toughest frequencies in the audible spectrum with quick ease. Forward mids that are precisely elevated for articulation in the most vital region of instruments and voices. Plenty of top end sparkle really separates Aspire 4 from any other UIEM in its class, making this powerful sound signature a perfect blend of accuracy and musicality.


Professional Heritage

Since 2010 we've crafted thousands of custom in-ear monitors for some of the world's greatest musical talent. Working with these discerning and critical entertainers has shaped our products and technological development, culminating in our most accessible UIEM to date. Sharing that same legendary DNA and patented technology, Aspire 4 is the ultimate UIEM for anyone who needs to HEAR LIKE A PRO.
