Letshuoer S12 Pro In Ear Monitors

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. The independent rear acoustic chamber design makes channel matching to be more consistent. In terms of sound performance, the structural design of the front and rear acoustic chamber effectively discharges the pressure inside the chassis, thereby attaining a more natural sound.

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. The chassis comes in a minimalistic profile, with not a lot of wiggle room within the acoustic chamber to minimize reverberation. Dual-pin receptacle is a separate piece protruded from the faceplate so that the irregular shape would not cause distortion.
