Unique Melody / UNM1086

Unique Melody / MEST MKIII CF is a high-end canal earphone that uses a dual conduction system that transmits sound using two methods: ""air vibration"" and ""bone vibration.""

■Exquisitely placed quad hybrid driver
・MEST MKIII CF boasts a combination of four types of drivers, and the dynamic driver is in charge of the low range. The BA driver is responsible for the mid-high range. Ultra-high frequencies are handled by electrostatic drivers, and silver-palladium alloy piezoelectric bone conduction provides complete frequency correction, providing superior layering and separation for everything from holographic imaging to 3D rendering. The impactful bass, texture of the midrange, and beautiful treble are all vividly displayed. The MEST MKIII CF is a breakthrough product that represents a major advancement in IEMs, surprising the ear with its perfect tuning and driver configuration. A silver-palladium alloy piezo bone conduction driver is the key to providing cohesiveness. Benefiting from bone conduction effects in all frequency bands, MEST MKIII CF creates a well-balanced sound thickness and density, an all-round experience, and excellent sound quality.

■Strengthened electrostatic type and optimized tuning
・Selecting an electrostatic driver improves frequency response range and treble extension. Your ears can pick up details in sounds that you wouldn't normally feel. Equipped with four electrostatic drivers, MEST MKIII CF has higher sensitivity, extremely low distortion, superior detail, and richer atmosphere. By placing greater emphasis on detail and volume in the bass range, it highlights delicate sound quality and produces a rich sound full of energy. It also uses bone conduction to transmit sound directly to the inner ear through bone contact, without passing through a nozzle. It has an ultra-wide frequency characteristic of 20Hz to 70kHz, and the dynamic driver and BA driver are responsible for 20Hz to 20kHz. The electrostatic driver is responsible for correction of all frequencies from 10kHz to 70kHz, and the silver-palladium alloy bone conduction is responsible for correction of all frequencies from 500Hz to 16kHz. Air conduction and bone conduction interact to create an innovative and completely new sound.

■Patented technology “Silver palladium alloy piezoelectric bone conduction driver”
-The silver-palladium alloy piezoelectric bone conduction unit consists of 27 layers of ceramic coatings, each 23-25μm thick. Each bone conduction unit is rigorously tested for capacitance, dielectric loss, displacement, and resonant frequency. Using high temperature resistant conductive palladium paste, the ceramic can be sintered at 980℃, fully guaranteeing the performance of the product. Compared to the 14-layer ceramic coating of double vibration bone conduction, silver-palladium alloy piezoelectric bone conduction has the characteristic of being multi-layered and thicker, which improves the vibration effect of bone conduction with high quality and makes the acoustic effect more prominent. The MEST MKIII CF adds a gold-plated PCB board and integrates all the dividers on the board for increased stability and consistency, and the gold plating improves conductivity. The circuit board uses high-precision components to ensure good sound quality and strong stability.

■Dedicated custom cable
-MEST MKIII CF uses a new customized cobalt blue shielded cable. This is a pure 4-core OCC copper cable with nylon sleeve and eco-friendly soft PVC coating, offering 26AWG, ultra-low resistance, low distortion, and the purest details.
