Ultimate Ears by Logitech has a loyal following of touring musicians, sound engineers and mainstream music lovers, due to the sound quality and comfortable fit of their earphones.

Ultimate Ears was founded in 1995 to address the sound-monitoring needs of on-stage rock musicians, developing the first high-performance two-way, custom in-ear stage monitors. An estimated 75 percent of today's top touring rock musicians now use the Ultimate Ears custom-fit in-ear monitor while performing. Since 2005, using patented, proprietary technology, Ultimate Ears has expanded its product line with universal-fit earphones for audiophiles as well as mainstream music enthusiasts.
