On May 31st, Ren Xianqi's "Qi Ji · 2025" Shenzhen concert will kick off at the Universiade Center. When AI acoustic black technology meets the music sentiment of the golden age of Chinese language, a visual and auditory carnival that revitalizes the memories of the times is about to explode this summer! As the "acoustic partner" accompanying Ren Xianqi across six cities, Cleer sets off once again with an exclusive naming identity, and will work together with Ren Xianqi's team to create an immersive music feast that is "heart warming" for fans. The story of Cleer and Ren Xianqi, from their first encounter in 2023 with "love at first sight" to their current ninth concert with "tacit coexistence", has already surpassed the simple cooperation between brands and spokespersons, becoming an industry legend of the symbiotic growth of intelligent acoustics and music art.

Strong Alliance | Cleer and Ren Xianqi's "Sound" Fate Meeting

Looking back at the collaboration between Cleer and Ren Xianqi, it was a two-way journey that began in 2023. In August 2023, Cleer officially announced Ren Xianqi as the brand spokesperson, and the two sides began a comprehensive cooperation in the music field such as concerts and new song MVs, deeply rooted in the hearts of the people with the strong alliance between high-quality Cleer headphones and music king Ren Xianqi. In 2024, the cooperation between the two sides will further deepen. In June, at Ren Xianqi's concert in Chengdu, the CEO of Cleer personally presented the renewal contract, writing a new chapter of cooperation in the form of a "birthday gift". Entering 2025, cooperation will reach a new peak. On April 22nd, the Cleer Global New Product Launch Event was grandly held at the Shenzhen Low Carbon City Airfilm Hall. Ren Xianqi was invited as a special guest to unveil the mysterious veil of the new generation Cleer ARC 5-tone arc open AI earphones and Cleer Clip star arc open AI earphones with the brand. At the concert with tens of thousands of people and on the stage of technology release, Cleer and Ren Xianqi always resonate on the same frequency, making the concept of "acoustic technology empowering music expression" deeply rooted in people's hearts.

Behind these deep interconnections is the shared commitment of both parties to the concept of 'ultimate'. As a "multi talented legend" in the Chinese music industry, Ren Xianqi not only established his position as an "evergreen tree" in the Chinese music industry with his popular hits such as "Heart Too Soft" and "The Girl Across from You", but also demonstrated an endless spirit of exploration in his more than 30 year career, constantly expanding his personal career boundaries and actively crossing multiple fields such as film and television, racing, etc. He always challenges boundaries with a breakthrough attitude, which resonates deeply with Cleer's parent company, Shenzhen Guanxu Electronics Co., Ltd., who has been researching acoustic technology for 28 years, accumulated over 3400 intellectual property rights, and completed the evolutionary trajectory from a leading OEM manufacturer to a leader in intelligent acoustics.

With a solid technological barrier built through continuous investment in core technology, Cleer's smart earphones have ranked 7th in the world in terms of patent applications (following closely behind Apple 5th and Qualcomm 6th), and have won over 100 international innovation and creativity awards, including the 2025 Geneva Invention Award, China Excellent Industrial Design Award, and US CE Week Gold Award. It has become one of the important drivers for China's smart acoustics industry to go global. When Ren Xianqi praised Cleer as the "new ear" that musicians cannot do without at the Cleer new product launch event in 2025, it was not only a recognition of the brand's technological strength and innovative achievements, but also a resonance with the "voice to heart" concept of both parties.

Acoustic Evolution | Cleer's Self Transcendence from Open Listening to Sound Quality Ceiling

From conceptual resonance to product implementation, Cleer's craftsmanship spirit is manifested in perceptible technological breakthroughs in acoustic research and development. From the early ARC Sound Arc series pioneering the open headphone track, to the ARC 5 once again breaking the ceiling of open headphone sound quality, every product of Cleer is fulfilling the promise of "using technology to restore the authenticity of sound". Since the debut of the first ARC sound curve in 2021, Cleer has leveraged "open listening" as a pivot to drive industry change - while traditional headphones are still pursuing the closed nature of physical noise reduction, Cleer has found a golden balance between sound quality and comfort through a suspended design that is "close to the ear but not in the ear". In 2024, this innovative spirit gave birth to ARC 3, which broke the technical barrier of "openness without noise reduction" for the first time. By virtue of the innovative integration of excellent sound quality and breakthrough AI noise reduction technology, it was outstanding during 618, and won the top 1 in the cumulative turnover list of three major industries, namely, Tiktok platform commodity list, store list and AV appliance list; During the Double 11 Shopping Festival, it was selected into the "Must Buy List on Double 11" of Tiktok and topped the hot sales list and buy back list of Tiktok AV appliances for many times, becoming a "phenomenal blockbuster" loved by users.

And with the latest release of ARC 5 Sound Arc this year, the sound quality ceiling of open headphones has been pushed to a new dimension. It integrates for the first time three of the world's top audio technologies: THX spatial sound effects, DTS spatial sound effects, and Dolby sound effects with head tracking, becoming the world's first open earphone to receive both THX certification and DTS endorsement. THX certified cinema grade sound field ensures precise reproduction and dynamic balance of sound; DTS spatial sound effects are known for their excellent multi-channel surround sound effects, allowing open headphones to showcase a multi-dimensional and wide sound field; Dolby sound effects with head tracking technology allow sound to adjust direction in real-time following head movements, as if you were in a music scene. Whether it's the stunning low-frequency impact or the delicate high-frequency resolution, ARC 5 can perfectly present in a precise, dynamic, and three-dimensional manner.

In terms of AI performance, ARC 5 has also taken a leap forward, equipped with Cleer's self-developed AI intelligent agent "Tingdao", which can easily perform tasks such as real-time transcription of AI voice notes and AI simultaneous interpretation, transforming from a listening device to a multifunctional AI productivity tool. Cleer is demonstrating through repeated technological iterations that open headphones not only break the physical constraints of traditional headphones, but also reshape the auditory experience with revolutionary sound quality and functionality. With multidimensional breakthroughs in acoustic technology and functional design, ARC 5 has already won high recognition in the industry before its official launch, winning honors such as the Bronze Award of the 2025 Geneva Invention Award and the 2025 German Red Dot Design Award. It also won the highest honor of the exhibition, the BEYOND BEST CHOICE Awards, at the recent BEYOND Expo 2025, fully demonstrating its top strength and market potential.

Future prospects | Using sound as a bridge, we can explore infinite possibilities together

Music is the bridge that connects people's hearts, while technology is the cornerstone that makes this bridge stronger and better. This is the belief shared by Cleer and Ren Xianqi. In the future, Cleer will continue to focus on technological innovation and explore the boundaries of sound quality, bringing users a more ultimate listening experience. Just as Ren Xianqi continues to break through style limitations on the path of music, Cleer will also constantly challenge himself in the field of acoustics, building more complete sound solutions from open headphones to intelligent acoustic ecosystems.

The "Qi Ji · 2025" Shenzhen concert by Ren Xianqi on May 31st will be a brilliant new chapter in this music and technology feast. Cleer cordially invites every friend who loves music to wear Cleer headphones and enter the concert venue with Ren Xianqi, to feel the warmth of music with their ears and touch the power of technology with their hearts. Let's look forward together to the collision of Ren Xianqi's singing voice and Cleer's acoustic technology, which will create a strong sound of the times!
