On November 7th, the "Deep Exploration of Standard Practice Empowering Industrial Upgrading - Advanced Standards' Look at Shenzhen 'Visit and Research Activity" visited Shenzhen Grandsun Electronic Co., Ltd. (hereinafter referred to as "Grandsun Electronic"). A delegation of representatives from the Shenzhen Municipal and District People's Congress, CPPCC members, market supervision departments, and media representatives participated in this visit to closely decode how Grandsun Electronic uses "standards" as anchor points to leverage industrial upgrading and global competitiveness.

As another vivid example of the deepening of the "Shenzhen Standards" strategy, this event not only explores the "vivid stories" of "Shenzhen time-honored brand" Grandsun Electronic in standard formulation, implementation, and iteration, but also listens to the "voices" of enterprises in the process of standard internationalization, building a "communication bridge" for government enterprise collaboration, and injecting "standard momentum" into the high-quality development of Pingshan's industry.

Building a standard foundation gives "innovation" a scale 

As one of the top 500 companies in Shenzhen, Grandsun Electronic has been based on standards and driven by innovation since its establishment in 1997, exploring a unique cycle path of "innovation defining standards and standards nurturing innovation".

Nowadays, this national level intellectual property advantage enterprise has established a solid "standard matrix": 162 international standards for products or technologies have been implemented, and 53 international standards are being accelerated; From acoustic technology and AI intelligent algorithms to green manufacturing and low-carbon management, enterprises deeply participate in the construction of multi-level standard systems in industries, groups, and localities, ensuring that technological breakthroughs are efficiently transformed within the regulatory framework.

At the same time, the company has established an internal quality management system covering the entire product lifecycle, represented by the Q/GXDZ series active noise cancelling headphone standard, which connects the three-level linkage of "national standard industry standard enterprise standard" and forms an innovative closed-loop of research and development, production, and quality control collaboration.

As of 2025, Grandsun Electronic, as a national level intellectual property advantage enterprise, has a research and development team of over 760 people, accounting for nearly one-third of the total number of employees; The average annual R&D investment remains stable at 9% to 12% of revenue, with a total of 3426 intellectual property applications (including 2845 patents). The number of patent applications for smart earphones ranks seventh in the world, following closely behind Apple and Qualcomm, and firmly occupying the top tier in the industry. As one of the few "acoustic giants" in China with independent acoustic laboratories, its technological strength has won over a hundred international innovation awards, providing a clear "standard scale" for the innovative achievements of "Shenzhen Intelligent Manufacturing".

Make 'green' a visible productivity

Entering the Guanxu Electronic Park located in Longgang Low Carbon City, Shenzhen, with over 65% green coverage, more than 200 ecological barriers constructed by planting, an intelligent "cloud brain energy consumption management system", and a green "zero carbon production line"... Here, the roar of machines is synchronized with the chirping of birds, and the rhythm of production runs parallel to the breathing of ecology.

Behind the process standards is the standards of people. Investing in things is investing in people, "said Wu Haiquan, CEO of Grandsun Electronic, in an interview. Only by respecting people and the environment in manufacturing can products truly have sustainable vitality.

This "forest factory" with a building area of 52000 square meters, based on the concept of "visible carbon emissions and controllable energy efficiency", embeds green standards into the entire production process: the annual power generation of the distributed photovoltaic system is 700000 kWh, the annual power saving of the old injection molding machine upgrade is 634000 kWh, the annual power saving of the air conditioning AI intelligent management system is 150000 kWh, and the annual carbon emissions are reduced by 476.73 tons; Realize circular purification and reuse of production and domestic water, weave a "green closed loop" from the source, and make green a computable and convertible "real productivity"

With quantifiable emission reduction achievements and standardized management system, Guanxu Electronic Low Carbon Park was selected as one of the top ten green cases in Shenzhen at the 2023 United Nations Climate Change Conference COP28 "China Corner" in Dubai; National level green factory, EU sustainable development organization NG gold certification, zero carbon factory certification, waste zero landfill certification and other qualifications are added; In October 2025, the company teamed up with Wuxi High tech Zone to win the "EU Green Transformation Award", becoming one of the typical representatives of Chinese companies' green transformation under the framework of China EU climate cooperation.

The green standard extends to the product end. In 2024, Cleer brand under Grandsun Electronic launched the world's first open zero carbon (carbon neutral) headphones - Cleer ARC 3 sound arc, with zero carbon emissions throughout the entire lifecycle; On World Earth Day 2025, Cleer ARC 5 Sound Arc and Cleer Clip Star Arc, two "Green Beauty Earphones", will continue their new journey. The carbon emissions during the manufacturing stage will be reduced to below 7%, far below the industry average, using "small headphones" to interpret the industry's pursuit of "big low-carbon".

Innovation leads, breaking industry boundaries

If green standards are the "ecological foundation" of Grandsun Electronic, then intellectual property is the "backbone" that supports innovation, and product innovation is the "sharp knife" for enterprises to explore the market. In the field of intelligent acoustics, the Cleer brand under Grandsun Electronic has always broken industry boundaries with innovation, transforming standardized technological accumulation into tangible product competitiveness.

The pioneer of global open AI earphones, the pioneer of global open zero carbon (carbon neutral) earphones, and the pioneer of global open AI noise cancelling earphones All of them are from the Cleer brand and continue to lead the new track of open earphones.

In 2025, Cleer's flagship new product, Cleer ARC 5 Sound Arc Open AI Earphones, made a stunning debut - as the world's first open earphone that integrates three international standards: Dolby sound effects, THX spatial audio, and DTS spatial audio, it breaks through the limitations of open earphone structure with multi-dimensional spatial sound field and high fidelity resolution, achieving a master sound quality experience of 360 ° surround sound. It is equipped with a 6-core 6-nanobelt AI engine neural network processor, injecting powerful computing power into the self-developed AI intelligent agent "Tingdao", and activating functions such as AI voice to note taking and AI simultaneous interpretation with just one click; A simple "Hi Cleer" can awaken the "AI new quality productivity" and transform headphones from "audio terminals" to "AI productivity tools".

In response to the pain point of "difficult noise reduction" in open earphones, the Cleer ARC 5 noise reduction version uses a combination of "AI chip+self-developed algorithm" to achieve a breakthrough of -15dB noise reduction and fill the technical gap.

Empowering design to seamlessly integrate luxury and technology

Innovation is not just about functional innovation, but also about aesthetic guidance. Cleer has collaborated with the chief designer of Rolls Royce Phantom to create a series of classic works that combine aesthetics and technology, including the world's first flexible display smart speaker "Mirage" Cleer Mirage, giving "sound" a visible luxury texture.

As the world's first open top AI headset, Cleer Clip achieves a dual breakthrough in lightweight and fashion. Traditional headphones suffer from excessive weight (generally over 200 grams), which affects comfort. However, Clip has reduced the weight to less than 40g through structural innovation and material optimization, making it a reality to wear headphones without burden all day long.

What's even more ingenious is its interchangeable headphone accessory design, allowing users to freely match and dress as they please, achieving personalized expression of "one headphone with multiple styles". This innovation has shifted the focus of head mounted devices from "functional orientation" to "aesthetic orientation", promoting the cross-border integration of technology and fashion.

With the dual advantages of design and technology, Cleer has won over a hundred international innovation and creativity awards, including the Geneva International Invention Award Gold Award, the China Excellent Industrial Design Award Gold Nomination Award, and the US CE Week Gold Award, allowing "Made in China" to be seen and heard on the world stage.
