The U3 universal-fit earphones are extremely versatile and possess impressive clarity and warmth for any instrument or genre. The U3 faithfully reproduces vocals and instruments and brings their overtones to life. With their musically inspiring sound signature, they are ideal for vocalists and instrumentalists, or anyone seeking accuracy and balance in their IEMs.

The U3 also features our innovative apex® technology. Apex (air pressure exchange) is an enhanced version from the previous technology that relieves air pressure caused by miniature speakers in a sealed ear canal. Apex gives you a superior listening experience that simply cannot be achieved by traditional IEM’s.

Like all 64 Audio universal-fit products, the U3 earphones are inherently noise-isolating and are designed to work well with a wide range of personal audio devices as well as all personal monitoring systems.
