Softears – RSV-MKII 5BA 4-Way Crossover IEM

The Softears RSV MK2 sets a new benchmark for reference-grade all-BA IEMs. It features 5 Balanced Armature Drivers on each side with a unique four-way crossover and four independent acoustic tubes. It uses Dual Knowles CI-22955 drivers for powerful yet textured bass with an upgraded dual-tube design that delivers punchy mid-bass and extended sub-bass without any bloat. The improved midrange ED driver offers lush vocals and precise imaging, while the SWFK composite driver produces fatigue-free highs. Softears has also utilized its patented dual-pressure relief and passive air-damping system balance ear canal pressure for exceptional comfort during long sessions. The ergonomic shells combine resin construction with CNC-machined alloy faceplates and a carbon-fiber V inlay. The package includes a high-purity 6N7 cryo-treated OFC cable with 4.4mm balanced and 3.5mm termination plugs, plus premium ear tips for a secure fit and superior audio experience. The RSV MK2 is designed for audiophiles seeking top-tier clarity, dynamic bass and refined tonality in an elegant yet durable form.
