The 64 AUDIO U4 universal-fit earphones were designed with bass lovers in mind. They are built on the revolutionary ADEL™ technology. Because of this technology and its effect on the human ear, they offer a listening experience that cannot be matched by conventional IEMs. In addition to having dedicated mid and high drivers, their proprietary dual low subwoofers produce powerful yet controlled bass. Previously, this sound could only be possible with large, bulky "over-the-ear" headphones, but due to their advanced design the U4s deliver the richness and low-end impact with ease. This product is ideal for drummers, percussionists, bass players and the like.
Like all 64 AUDIO universal-fit products, the U4 earphones are inherently noise cancelling and are designed to work well with a wide range of personal audio devices as well as all Personal Monitoring Systems.
