The Ultimate Ears journey began in the back of a Van Halen tour bus in 1995, when they developed the first in-ear monitor to help drummer Alex Van Halen protect his hearing and improve his performance. Over the last 25 years, Ultimate Ears' relentless pursuit of innovation and craftsmanship has led them to the world’s biggest stages as the monitor-of-choice for thousands of legendary artists, from the Eagles to Ben Harper to Lady Gaga.
