In the fiercely competitive TWS earbuds market, sound quality remains one of the key factors in determining whether a product stands out. With the growing demand for high-quality audio experiences, Huawei has set a new benchmark with its flagship TWS earbuds, Huawei FreeBuds Pro 4, combining cutting-edge technology and unmatched sound quality.
This innovative wireless earbud is centered on delivering exceptional sound and groundbreaking technology. Huawei achieved this through breakthroughs in audio technology and close collaboration with the Central Conservatory of Music’s premier tuning team, ensuring every note evokes profound emotional resonance.
Revolutionary Audio Technology
On December 18, two in-depth interview videos were released, unveiling how Huawei FreeBuds Pro 4, supported by end-to-end audio technology and precise sound tuning, restores the beauty of original sound. Professor Yang Gefang, a violin professor and doctoral advisor at the Central Conservatory of Music, praised the collaboration:
“The tuning has surpassed the sound quality of leading global headphone brands. While past tuning was about beautifying sound, this approach enables hardware to achieve completeness, reproducing the most authentic original sound without deliberate enhancement.”
2.3Mbps High-Resolution Lossless Audio
Huawei has made significant investments in audio R&D, with seven global research centers, over 1,000 audio team members, and numerous patents. The FreeBuds Pro 4 benefits from over 500 patented innovations, including Huawei’s Kirin A2 chip, the proprietary Polar Code technology for Starflash connections, and the self-developed L2HC 4.0 Lossless Codec Protocol, making it the industry’s only TWS earbud to support 2.3Mbps lossless transmission. It is also certified with the HWA Lossless Gold Label, capable of delivering 48kHz/24-bit high-quality lossless audio.
Perfect Tuning by Experts
Sound quality ultimately lies in the listening experience, and artistic tuning plays a critical role in bringing the sound to life. Renowned violinist Jin Haiyin emphasized this integration of technology and art:
“By combining science and artistry, we bring authentic sound to the public, ensuring the highest standards for an unparalleled auditory experience.”
Huawei partnered with the Central Conservatory of Music’s top tuning team to fine-tune the FreeBuds Pro 4. Leveraging their expert “golden ears,” the team injected rich cultural depth into the earbuds. The result is the ability to reproduce live-like sound with precision and depth.
Two tuning modes were introduced during this process:
“Master Classical Sound” mode: Designed for classical music lovers, it replicates the acoustics of a concert hall’s “golden position,” revealing every nuance.
“Master Balanced Sound” mode: Tailored for pop and cinematic music, it balances vocals and effects to vividly recreate scenes with immersive sound.
Notable Highlights
- Huawei Yuezhang Certification: FreeBuds Pro 4 is Huawei’s first “Yuezhang” certified earbud, setting scientific benchmarks for sound quality assessment, moving beyond subjective interpretations.
- Advanced Features:
Dual-way quiet calling with up to 100dB background noise cancellation for clear conversations.
Integration with HarmonyOS NEXT ensures seamless pairing with Huawei flagship phones for a smarter ecosystem.
Summary
While many TWS manufacturers aim for “good enough” sound quality, Huawei aspires to redefine industry standards through cutting-edge technology and expert tuning. The FreeBuds Pro 4 delivers unmatched sound quality, thanks to rigorous innovation and the contributions of top musicians.
Renowned violinist Jin Haiyin praised the collaboration:
“These earbuds perfectly replicate the feel of a live performance, with unparalleled spatial, depth, and positional accuracy. Particularly in recreating the fixed positions of instruments in a symphony orchestra, the professionalism is extraordinary.”
This seamless fusion of technological innovation and artistic aesthetics sets a new industry benchmark, making every listening experience as authentic as being at a live performance.
