10MM CARBON DIAPHRAGM DYNAMIC DRIVER: Blon Bl03 IEM is equipped with 10mm Carbon diaphragm dynamic driver, which is designed to enhance the sound quality by reducing the mid-low frequency drum point and providing a more powerful and dynamic bass experience. The carbon diaphragm is lightweight yet rigid, allowing it to vibrate more efficiently and accurately, resulting in improved sound clarity and detail.

KIRSITE MIRROR POLISHED METAL SHELL FOR STUNNING APPEARANCE: The BLON BL-03 earphones are designed with a Kirsite mirror polished metal shell, giving them a stunning and eye-catching appearance. The heart-shaped cavity design adds a unique touch to the earphones, while the mirror polishing creates a sleek and elegant look.

U SHAPED SOUND SIGNATURE: The BLON BL-03 earphones are designed with a smooth U-shaped sound signature that ensures a seamless transition between the lower, mid, and higher-end frequencies. This creates a clear and balanced sound that is free from any muddiness or overlapping, allowing for crisp sound reproduction.

HIGH QUALITY STOCK CABLE: BLON BL-03 earphones come with a high-quality stock cable that features a 2-pin 0.78mm connector and a 3.5mm jack. The 2-pin connector ensures a secure and stable connection between the earphones and the cable, preventing any audio dropouts or disruptions.

ERGONOMIC DESIGN AND COMFORTABLE TO WEAR: The BLON BL-03 earphones are designed with an ergonomic shape that fits comfortably in the ear canal. The earphones are molded based on professional ear canal data analysis, ensuring that they fit securely and comfortably for extended periods of use.

COMPLIMENTARY EARPHONE CASE: We provide complimentary earphone case as a good gesture to all our customers to protect IEMs from Scratches, rain/water and dust. High quality Leatherette material can prevent moisture. Unique appearance is suitable for carrying. It is soft, comfortable and durable.
