S12 PRO in Ear Headphones 14.8mm Planar Magnetic Driver Wired HiFi Earphones for Smartphones/PC/Tablet (Deep Space Blue, 2.5mm / 3.5mm / 4.4mm Connector)

Custom 14.8 mm planar magnetic driver - This unit employs a custom 14.8 mm large-diaphragm driver for excellent detail retrieval, dynamic bass, and crisp trebles. 102dB high sensitivity ensures it can be easily driven to volume, whether from a cell phone or dongle DAC, and will perform optimally when paired with most sources or amplifiers. Balanced chassis design - The chassis design continues from the predecessor. Multiple vent holes on both sides effectively alleviate negative pressure build-up within the ear canal, thus protecting hearing. Swappable jacks on stock cable - The stock cable is built with silver-plated monocrystalline copper, with four 98-strand cores woven together.

It is terminated in standard 0.78 mm dual-pin connectors, and the other end features a swappable jack with 2.5 mm, 3.5 mm, and 4.4 mm options. This system is compatible with a great amount of source gear and IEMs. Five-axis machining process - The aluminum chassis is shaped for a snug fit in the concha. The finish is smooth to the touch due to the five-axis CNC machining process. It is strong, durable, and without sharp edges
