August 27th, 2025 — Together with USound, the leading provider of MEMS (Micro-Electro-Mechanical Systems) speaker technology, we are proud to announce that the MeloBuds N70 integrates USound’s MEMS tweeter. This milestone highlights the arrival of high-resolution, distortion-free sound powered by MEMS speakers in the mainstream consumer audio market.
The MeloBuds N70 features our DualCore Acoustic System, combining the Obo Pro.2 ring-shaped dynamic driver with the USound MEMS tweeter. This dual-driver approach allows us to deliver audio that is precisely tuned for authentic sound reproduction, free of distortion—raising the benchmark for true wireless stereo (TWS) earbuds.
“This launch proves that MEMS speakers are no longer a future promise—they are here today, delighting consumers,” said Ferruccio Bottoni, CEO of USound. “Our collaboration with QCY demonstrates how USound MEMS technology enables smaller form factors, superior performance, and reliability unmatched by legacy dynamic speakers.”
“The MeloBuds N70 perfectly integrates high-fidelity sound, noise-cancellation technology, and a lightweight design. Through close collaboration with USound, we will continue to launch more innovative TWS products in the future, bringing a higher-quality listening experience to users worldwide,” said Wei Shiweng, our Chief Acoustic Engineer.
Key Benefits of USound MEMS Technology in Our MeloBuds N70:
Ultra-Wide Frequency Response – Hi-Res level performance up to 40 kHz+, delivering superior high-frequency detail compared to legacy dynamic drivers.
Low Distortion and High Consistency – Semiconductor-grade precision ensures minimal variation across units and consistently clear sound.
Compact, Lightweight, and Energy-Efficient – Optimized for TWS form factors, reducing housing volume and power consumption.
Hi-Res Certified Audio Potential – MEMS technology positions the MeloBuds N70 for Hi-Res Audio certification, enhancing the immersive listening experience.
With features such as Adaptive Hybrid Active Noise Cancelling, long battery life, and ergonomic design, the MeloBuds N70 combines USound MEMS speaker advantages with our innovation in wireless audio. The MeloBuds N70 with USound MEMS tweeters is now available globally through Amazon and our distribution partners.
We will continue to work closely with USound, jointly exploring the combination of high-fidelity sound and intelligent interaction to usher the wireless audio industry into a new era.
The MeloBuds N70 is now available for purchase worldwide. Consumers can order directly via our official website and major online retailers such as Amazon.
