- Custom 14.8mm planar magnetic driver - The S12 pro utilize a custom 14.8mm large-diaphragm driver with great details retrieval, punchy bass and clear trebles. 102db high sensitivity means that it can be easily driven to volume, be it a cell phone or dongle DACs, S12 will sound optimal pairing with most source / amps.
- Balanced chassis design - S12 Pro’s chassis design is a continuation of the predecessor. Multiple vent holes on both sides are effective in alleviating negative pressure build up within the ear canal, and thus protecting the hearing.
- Swappable jacks on stock cable - The stock cable is constructed with silver-plated monocrystalline copper, and four 98-strands cores are then weaved together. It is terminated in standard 0.78mm dual pin connectors, and the other end is a swappable jack with 2.5mm / 3.5mm / 4.4mm jacks. This system will work with a great amount of source gears and IEMs.
- Five-axis machining process - S12 Pro’s aluminum chassis is shaped to have a snug fit in the concha. The finishing is smooth to the touch thanks to the five-axis CNC machining process. It’s strong, touch and without sharp edges.
