Choseal (Chinese: 秋叶原, often styled as Choseal 秋叶原) is a Chinese manufacturer and brand specializing in cables, connectivity products, audiovisual transmission systems, structured cabling, and related intelligent connection equipment. The brand originated in Shantou, Guangdong, in 1989 before relocating its operational headquarters to Shenzhen. It operates under the primary corporate entity Shenzhen Choseal Industrial Co., Ltd. and is part of the broader Guangdong Qianhai Choseal Group. 1

The company’s product range serves both consumer electronics markets—offering HDMI, USB, Ethernet, and audio cables—and professional engineering applications, including structured cabling for security systems, audiovisual installations, stage systems, and smart-building infrastructure.

Foundation and Early Years (1989–1997)

According to official corporate records, Choseal was founded by Sun Yikai in Shantou, Guangdong, in 1989. The initial business focus was specialized, centering on high-end audio cables and high-quality AV connection cables. This established the brand’s roots in signal transmission rather than general consumer electronics.

In 1997, the company moved its operating base to Shenzhen. This relocation coincided with an expansion into OEM manufacturing and retail/supermarket distribution channels. Shenzhen subsequently became the central hub for Choseal’s corporate and commercial activities.

Product Diversification (1997–2003)

During this period, Choseal broadened its portfolio beyond traditional AV cables. New additions included intelligent engineering cables, power converters, and additional cable varieties. The company also developed further R&D and manufacturing capabilities, marking the beginning of its transition toward an integrated model combining research, production, and sales.

Brand Expansion and Recognition (2005–2014)

Between 2005 and 2006, Choseal increased its national visibility through involvement in projects such as the “Olympic Lecture” (奥运大讲堂), which included a nationwide dealer conference at the Great Hall of the People in Beijing. In 2007, the Choseal/秋叶原 brand was recognized as a Guangdong Famous Trademark.

Manufacturing capacity expanded significantly in 2008 with the opening of a factory complex in Huizhou covering more than 50,000 m². This facility included copper and PVC-related business units, allowing the company greater control over upstream materials. During 2008–2010, Choseal’s cable products received recognition in the “Safe City” construction sector.

In 2013, the company entered a strategic partnership with JD.com, launching a comprehensive online-sales strategy. This shift made Choseal visible not only to professional installers but also to ordinary consumers purchasing cables and computer accessories. By 2014, the brand received recognition as a “China Famous Trademark” (中国驰名商标), positioning it among the early recipients of this status in China’s security-cable industry.

Modern Era (2015–Present)

From 2015 to 2017, Choseal enhanced its R&D and manufacturing positioning, achieving High-Tech Enterprise status and appearing in various Guangdong manufacturing rankings. From 2018 onward, the company increasingly focused on security cabling, smart cities, IoT, AV systems, structured cabling, and system integration. In 2018, the China Ordnance Society Security Research Institute Shenzhen Branch was established at the company’s headquarters.

In recent years, Choseal has moved toward high-bandwidth connectivity solutions. Its current portfolio includes HDMI 2.1/8K products, optical-fiber HDMI, Cat 8 Ethernet, professional audio cables, SDI, low-smoke zero-halogen cables, stage AV products, 3C digital accessories, and smart-home connectivity. This evolution reflects a transition from a traditional cable maker to a broader connectivity and system-integration brand. 2

Choseal is primarily a brand operated by several legal entities within a larger corporate structure. The principal operating company is Shenzhen Choseal Industrial Co., Ltd. The parent group is described as the Guangdong Qianhai Choseal Group, whose activities extend beyond cables into industrial parks and technology-oriented services. The group operates two main brands: Choseal/秋叶原 and Mengke Park/梦科园. 1

Headquarters and Manufacturing

As of current information, Choseal’s headquarters is located in Bao’an District, Shenzhen, Guangdong. Key manufacturing bases are situated in:

• Huizhou, Guangdong: Historically significant for the company’s manufacturing infrastructure.
• Shanwei, Guangdong

The English-language website lists the headquarters address as Zhongliang Chuangzhi Factory Zone 67, Xin’an, Bao’an District, Shenzhen, and identifies the Choseal industrial park in Huizhou as a primary manufacturing site.

Choseal’s product catalog is extensive, covering consumer electronics, networking, professional AV, and engineering infrastructure.

HDMI and Video Cables

HDMI represents one of the brand’s most recognizable consumer categories. Products include conventional HDMI cables and newer high-bandwidth variants designed for 4K, 8K, high refresh rates, HDR, eARC, home theater, gaming, and professional AV installations. Flagship engineering products include optical HDMI cables supporting configurations such as 8K 60 Hz, 4K 120 Hz, HDR, and eARC. The company also offers long-distance optical HDMI products capable of transmission over distances up to 150 meters in suitable configurations. 3

Ethernet and Networking

Networking is a major product family for Choseal. The catalog ranges from Cat 5e to Cat 8, including shielded and unshielded options, outdoor networking cables, patch cables, network modules, keystone accessories, patch panels, RJ45 connectors, and cable-management products. Current Cat 8 engineering products advertise 40 Gbps transmission speeds and bandwidth up to 2000 MHz, utilizing double shielding and thick conductors. These products serve both home networking and professional structured cabling needs. 4

Audio Cables

Audio remains a core area, reflecting the company’s origins. The portfolio includes 3.5 mm audio cables, RCA cables, hybrid 3.5 mm–RCA cables, 6.35 mm audio cables, XLR cables, instrument cables, coaxial digital audio, optical audio, and professional audio interconnects. These products are marketed for applications ranging from home entertainment to recording, live performance, microphones, musical instruments, and professional AV systems. 5

USB and Digital Accessories

Choseal sells a wide array of consumer connectivity items, including USB cables, extensions, adapters, USB-C products, charging/data cables, computer peripheral cables, display adapters, and other 3C accessories. This category allows the brand to appear as a consumer electronics accessory provider on e-commerce platforms, distinct from its engineering-focused identity in professional catalogs.

Professional Engineering Products

A significant portion of Choseal’s business involves infrastructure components for engineering projects and system-integration solutions. This includes structured cabling, security systems, surveillance, AV installations, conference systems, data rooms, smart buildings, public-address systems, and stage/entertainment systems.

Low-Smoke and Fire-Safety Cables

The company produces LSZH (Low-Smoke Zero-Halogen) cables intended for environments where smoke and corrosive gases during fires are critical safety considerations. These are promoted for use in large buildings, public facilities, data rooms, security systems, commercial buildings, and engineering projects, emphasizing safety, environmental characteristics, durability, and stable transmission.

Choseal’s positioning has evolved from a high-quality audio/AV cable manufacturer in the late 1980s to an integrated connectivity and intelligent-engineering brand in the 2020s. Today, it describes itself as serving the audiovisual, structured cabling, and system-integration markets.

The brand occupies a unique position between budget generic cables, mass-market accessory brands, and premium audiophile or specialized engineering manufacturers. Its competitive advantage lies in the combination of vertical manufacturing capabilities, a large product range, engineering experience, and strong distribution networks in both physical retail and e-commerce. This allows Choseal to sell affordable consumer cables while simultaneously participating in large-scale structured cabling and AV projects.

Choseal maintains a substantial presence in Chinese e-commerce alongside its traditional engineering distribution. Official sales channels include Tmall, JD, Pinduoduo, and Douyin/TikTok-related platforms. 6 The JD storefront features a broad selection of networking, HDMI, USB, and other connection products.

Choseal has accumulated various industry recognitions and certifications within China, including:

• Guangdong Famous Trademark (2007)
• Safe City construction product recognition (2008–2010)
• China Famous Trademark (2014)
• High-Tech Enterprise status
• Rankings in Guangdong and Shenzhen enterprise lists
• Specialized and Innovative (“专精特新”) enterprise designation
• National Enterprise Standard Leader recognition in multiple product categories
• Continued Enterprise Standard Leader recognition from 2023 through 2025

The company’s official site references several major projects and venues where its products have been utilized, demonstrating its engineering and system-integration capabilities. These include:

• Beijing National Stadium
• Beijing APEC Main Venue
• Shijingshan Gymnasium
• National Theatre of Senegal
• Shanghai World Expo China Pavilion
• Shanghai Tower

These references indicate project participation rather than exclusive supply of all components within these venues.

Choseal is best understood as a long-established Chinese connectivity manufacturer that has expanded from niche audio cables to a broad ecosystem of digital and engineering connectivity solutions. As of 2026, the company actively emphasizes high-speed networking, optical HDMI, professional audio, and smart infrastructure while maintaining its large consumer-oriented cable catalog. 7 The brand’s longevity, vertical manufacturing, and dual focus on consumer and professional markets define its current identity. 8
