Know before you buy
No, you don't necessarily need one. With a sensitivity of 102dB/mW and low impedance, these earphones are efficient enough to be driven easily by most smartphones, tablets, or standard laptop headphone jacks.
The 14.8mm planar driver provides a fast, clean, and highly detailed sound. You can expect quick transient response and extended treble, which results in a wider soundstage and better instrument separation compared to many traditional dynamic drivers.
Yes, the S12 features an ergonomic chassis with a dual vent hole system that helps equalize pressure in the ear canal. This design reduces the 'suction' feeling often associated with sealed in-ear monitors, making them more comfortable for extended use.
Yes, the S12 uses a standard 2-pin connector system. This allows you to easily swap or upgrade the cable if you prefer a different length, material, or termination type.
The chassis is crafted from a single piece of aluminum using a 5-axis CNC process. This construction method ensures a robust, lightweight, and smooth finish that is designed to withstand daily wear and tear.
The S12 carries an IPX3 rating, meaning they are protected against light sprays of water. While they are fine for a light commute, they are not designed for heavy sweat or submersion, so they are best suited for indoor or casual listening.
