These earphones provide a clear, expansive and rich audio experience with clear midrange and high-pitch sounds. The product employs a balanced armature driver that excellently reproduces midrange and high-pitch sounds and is frequently used for monitor headphones. To realize clear and expansive midrange and high-pitch sounds and sharp bass sound, our originally developed Sonic Resonating Structure and highly rigid brass housing are employed. This product's shape represents a drop of water and its characteristic rich sound.
