The first mass-produced 3D printed quad balanced in-ear monitor. The result is a remarkably consistent sound between the FA7 pairs as well as reduced sound resonances that allow for smooth music flow. Hi Res monitors with four Knowles converters, body made of high quality resin. The bass is equipped with the CI-22955, which provides a robust yet fast bass with low distortion due to the fact that the membrane is much larger than a typical BA controller. Wednesdays are equipped with classic and proven ED-29689, with full, sweet and thorough sound. The tweeter is made from the double BAF SWFK-31736 driver, which is specially adapted for the FA7 to deliver extremely extended and detailed heights, for extra natural and clear sound. The FA7 standard cable is the LC-3.5B and is made of the finest pure silver wire terminated with MMCX connectors. The FA7 shell texture resembles water ripples that naturally come with turbulent waves or gently flowing currents, giving IEM a strong yet elegant look. In addition to the two cases, the Fa7 is equipped with 13 pairs of extensions that differ not only in size but also in acoustic tuning. There are 3 different sets of small, medium and large attachments designed for balanced bass and vocal sound, 3 pairs of medium sized and one silicone pair.
