1 Year Manufacturer's Warranty


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.

Hari Narayanan (Ernakulam, IN)
Great sound but faulty

I received a pair of faulty iems and concept kart are politely helping me get a replacement. Great customer service.

Pritish P. (Jaipur, IN)
Blon BL03 as per expectations, they're awesome.

BL03 IEMs are great to have, wide sound stage which u won't find in sony headphones like MDR-EX155AP OR MDR 255AP. Small ear👂 beware you've to buy a pair of buds for best fit. Spinfit buds are perfect pair for this IEMs.

I've attached my Sony MDR Ex155ap buds and works well with them.

suggestion for concept kart, instead case please provide a pair of earbuds with this. Really great deal it will become.

Blo(w)n away
I had Sennheiser cx275s compared to that this is mile ahead in clarity and soundstage vocals are perfect you can hear more instruments and even a smaller amount of details but this need a burn-in time like 10 hrs or more than that
Cable quality is not that much horrible as many reviews fitting is also good not that bad and absolutely have to change the tips
And thanks for the concept kart for perfect timely delivery and free earphone case And guys we all can trust this website 👍🏻

Thank you for your kind words. We really appreciate the time you took to write such a detailed review

Sanzy (Guwahati, IN)

Just received my first IEM.
Pros: Sounds great for my taste. Proper quality. Great pakage.
Cons: Earbuds issue(loose). Stuck on my ear tbh on first try xD.

Prasanth gunipe (Roorkee, IN)
Best IEM at any price point

I have tried many budget iems from kz, cca, moon drop, and seltos and many high end iems like tin t3 plus, aria, etc. But the amount of enjoyment i get while listening blons is next level. No of the iems i tried came close to blons.
