KO-STAR NBC90 ANC TWS Earbuds Wins Industry Golden Ear's Choice Award
2026-04-24
Great news for audio lovers: our KO-STAR NBC90 TWS earbuds have officially earned the prestigious CAIA CGEC Golden Ear's Choice Certificate — a top industry recognition reserved only for products that pass rigorous sound quality evaluations.
What Makes This Award Special?
Hosted by the China Audio Industry Association (CAIA), the Golden Ear's Choice is no easy win. To qualify, products must pass three critical tests: subjective listening evaluation, total harmonic distortion (THD) checks, and left-right channel consistency assessments. The NBC90’s win is third-party proof that our engineering delivers true, studio-grade sound quality you can trust.
The Tech Behind The Award: NBC90’s Standout Features
Let’s break down the performance that made the NBC90 a winner, and how it elevates your daily listening:
1. 10mm Neodymium Driver: Pure, True-to-Life Sound
At the core of the NBC90 is a 10mm neodymium full-band speaker unit, which was key to acing the award’s sound quality tests. The oversized driver delivers dynamic bass, rich mid-range tones, and crisp, distortion-free treble — no flat audio, no imbalanced frequencies, just every note as the artist intended.
2. ANC+ENC Noise Reduction: Clarity For Every Scenario
Award-winning sound isn’t just about music — it’s about being heard, too. The NBC90 features 25dB active noise cancellation (ANC) to block out background noise like traffic, office chatter, or plane engines. Combined with ENC call noise reduction, you’ll get crystal-clear voice calls even in busy environments. Switch between 4 modes (Noise Canceling, Transparent, Gaming, Music) to match your day.
3. Bluetooth 6.0 + 30-Hour Battery Life
Great audio needs great connectivity. The NBC90 uses upgraded Bluetooth 6.0 for a stable, low-power connection up to 10 meters away — no dropouts, no lag. Plus, enjoy up to 6 hours of playtime on a single charge, with the compact charging case adding 24 extra hours for a total of 30 hours of use. Perfect for all-day commutes, work trips, or weekend adventures.
4. App Customization + All-Day Comfort
The NBC90 is built for your life. Use the KO-STAR app to customize touch controls, pick from 6 EQ sound effects, enable low-latency gaming mode, or even locate lost earbuds. The ergonomic, lightweight design fits securely in your ears, whether you’re working out, running errands, or working at your desk.
