Never will you find an IEM like the Shanling ME700. Featuring a hybrid driver configuration, premium accessories and a luxurious design, each ME700 has been crafted from cultured marble. The delicate white veins over the deep black background ensure a design that #39;s unique amp; exquisite. Due to this, no two ME700s look the same. The Shanling ME700 has been certified Hi-Res by the Japan Audio Society thanks to its drivers that can reach a frequency of even 40,000Hz. However, to experience high-resolution sound at its full potential, it is recommended that it be used with Hi-Res audio players. The Shanling ME700 houses a 24k gold-plated dynamic driver which helps in delivering a cleaner, tighter bass along with a lush and natural overall sound output. It also includes four custom-designed balanced armature drivers. These include two larger drivers for the midrange amp; lower treble and two combined drivers for the higher frequencies. The Shanling ME700 utilizes a special octa-core Neotech silver cable for detailed sound and better high-frequency output without any disturbances. Aviation-grade stainless steel which is resistant to corrosion is included in all parts of the cable. The cable terminates into a 2.5mm connector for a balanced sound. For improved signal transmission, Shanling engineers have employed an advanced welding process.
