TRN has released its latest IEM, the TRN X7. As the name says X7, the pair features seven balanced armature drivers per side. The X7 has been designed with a specially-developed sound duct system that serves as an independent 3-channel frequency crossover system. 3D printed medical-grade resin material was used for the shells. The hypo-allergenic medical-grade resin is specially imported from Germany.
TRN X7 uses seven customized BA drivers per side. A customized 22955 low-frequency driver, two customized 50060 for upper midrange and high-frequencies, one customized 29689 for lower-midrange and bass response, and three customized 30095 drivers for treble frequency reproduction.
TRN X7 uses a 3-channel independent sound duct system (acoustic tubes) for physical frequency crossover and a professional audio-grade electronics SMT surface-mount PCB Board for electrical frequency crossover.
TRN packs the latest X7 with a 4-core silver-plated cable. Other accessories include an aluminum earphone case, 6.35mm adapter, airline adapter, seven pairs of ear tips.
