Powerful Bass, Hi-Fi Sound

The PLEXTONE FRO NB3 is built around a 10mm Hi-Fi dynamic driver with a 15% low-frequency boost, delivering deep bass and fine detail. An 18 Hz–20 kHz frequency response lets you hear every explosion and footstep in-game with clarity.

Dual Noise Immunity, Cleaner Audio

The in-ear design combines physical isolation from ambient noise with an advanced control system that pushes white noise to a minimum. The result is purer sound that keeps you immersed in the detail, distraction-free.

Clear Mic for Calls & Team Chat

An omnidirectional microphone captures your voice cleanly from every angle, making team comms and calls clearer whether you're gaming or running. It's tuned for both competitive chat and everyday use.

Ultra-Pure Copper Cable, No Interference

The 120 cm cable is made from 99.995% high-purity crystal copper with a tear-resistant 500D build that eliminates crosstalk and electrical noise. It's a stable connection that preserves audio purity from the first second.

Light & Comfortable for Sport and Gaming

At just 3.7 g per earbud and with reverse ear-mould tech, it delivers a stable, comfortable fit through long hours and won't fall out while you run. A high-strength polycarbonate shell pairs durability with lightness.

3.5mm Connection, Wide Compatibility

With a comfortable L-shaped 3.5mm plug, the NB3 works with Samsung, Xiaomi, Redmi, Oppo, Huawei, and Vivo phones, plus Asus and MSI laptops and PS4 and PS5. Instant readiness across all your favorite devices.
