Choseal (Chinese: 秋叶原, often styled as Choseal 秋叶原) is a Chinese brand that specializes in cables, connectivity products, audiovisual transmission, structured cabling, and related intelligent connection equipment. The brand originated in Shantou, Guangdong, in 1989 before moving its operating base to Shenzhen. It is associated with Shenzhen Choseal Industrial Co., Ltd. and the broader Guangdong Qianhai Choseal Group. 1

Its product line targets both consumer electronics—including HDMI, USB, Ethernet, and audio cables—and professional or engineering applications, such as structured cabling, security systems, audiovisual installations, stage systems, and smart-building infrastructure.

The company describes Choseal not merely as a consumer cable manufacturer, but as a brand serving the audiovisual, structured cabling, and system-integration markets. 2

Foundation and Early Years

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

In 1997, the company moved its operating base to Shenzhen and expanded into OEM manufacturing and retail/supermarket channels. Shenzhen subsequently became the center for Choseal’s corporate and commercial activities.

Product Diversification (1997–2003)

During this period, Choseal broadened its portfolio beyond AV cables to include:

• Intelligent engineering cables
• Power converters
• Additional cable products
• Related R&D and manufacturing capabilities

This era marked the beginning of the company’s transition toward an integrated model of research, development, manufacturing, and sales.

Brand Visibility and Recognition (2005–2014)

Between 2005 and 2006, Choseal participated in the “Olympic Lecture” (奥运大讲堂) project, which included a nationwide dealer conference at the Great Hall of the People in Beijing. The company cites this as a key step in building national brand recognition.

In 2007, the Choseal/秋叶原 brand was recognized as a Guangdong Famous Trademark. A major manufacturing expansion followed in 2008 in Huizhou, where a factory complex exceeding 50,000 m² began production alongside copper and PVC-related business units. This move aimed to give the company greater control over upstream materials. During 2008–2010, the company reports that its cable products received recognition in the “Safe City” construction sector.

In 2013, Choseal entered a strategic partnership with JD.com, initiating a more comprehensive online-sales strategy. This increased visibility among ordinary consumers buying cables and computer accessories, in addition to professional installers.

In 2014, Choseal states that 秋叶原 received recognition as a “China Famous Trademark” (中国驰名商标). The company describes itself as one of the early firms in China’s security-cable industry to achieve this status.

High-Tech and Smart Infrastructure (2015–Present)

From 2015 to 2017, the company expanded its R&D and manufacturing positioning, later reporting recognitions such as High-Tech Enterprise status and appearances in Guangdong manufacturing rankings.

Since 2018, Choseal has increasingly positioned itself around security cabling, smart cities, IoT, AV systems, structured cabling, system integration, and intelligent connection products. In 2018, the China Ordnance Society Security Research Institute Shenzhen Branch was established at its headquarters.

In recent years, Choseal has moved further toward high-bandwidth connectivity, including HDMI 2.1 / 8K products, optical-fiber HDMI, Cat 8 Ethernet, professional audio cables, SDI, low-smoke zero-halogen cables, stage and professional AV products, 3C digital accessories, and smart-home engineering connectivity. 3 As of 2026, the company actively emphasizes high-speed networking, optical HDMI, professional audio, engineering cables, smart connectivity, and system integration while maintaining its large consumer-oriented cable catalog. 8

There are two names commonly associated with the brand:

• CHOSEAL: The English/Latin brand name.
• 秋叶原: The Chinese brand name, pronounced approximately Qiūyèyuán.

Both refer to the same entity. In China, products are frequently labeled as 秋叶原（CHOSEAL）.

Choseal’s portfolio extends significantly beyond standard HDMI cables.

HDMI and Video Cables

HDMI is one of its most recognizable consumer categories. Products include conventional HDMI cables and newer high-bandwidth versions designed for 4K, 8K, high refresh rates, HDR, eARC, home theater, gaming, and professional AV installations. Current flagship engineering products include optical HDMI cables, with configurations supporting 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 m in suitable configurations. 4

Ethernet and Networking

Networking is a major product family, ranging from Cat 5e through Cat 8, including shielded and outdoor versions. The catalog includes patch cables, network modules, keystone-style accessories, patch panels, RJ45 connectors, and cable-management products. Current Cat 8 engineering products advertise 40 Gbps transmission and bandwidth up to 2000 MHz, utilizing thick conductors and double shielding. 5 This makes the company relevant to both home networking and professional structured cabling.

Audio Cables

Audio remains a core area historically linked to the company’s origins. The portfolio includes 3.5 mm audio cables, RCA cables, 3.5 mm–RCA adapters, 6.35 mm audio cables, XLR cables, instrument cables, coaxial digital audio, optical audio, and professional audio interconnects. 6 These products serve applications ranging from home entertainment to recording, live performance, microphones, musical instruments, and professional AV systems.

USB and Digital Accessories

Choseal sells a wide range of consumer connectivity products, including USB cables, extension cables, adapters, USB-C products, charging/data cables, computer peripheral cables, display adapters, and other 3C accessories. Depending on the channel, the brand can appear as an engineering cable company in professional catalogs or a consumer electronics accessory brand on e-commerce platforms.

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 installation, 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 products broadly serve five market segments:

1. Consumer Electronics: TV, PC, game consoles, routers, smartphone/tablet accessories, home theater, speakers, and headphones.
2. Home Networking: Home Ethernet, Wi-Fi router connections, smart TVs, NAS, gaming setups, home servers, and CCTV.
3. Professional AV: Conference rooms, broadcast, recording, stage production, digital signage, professional audio, and home cinema.
4. Security: CCTV, access control, surveillance, security networks, and smart-city infrastructure.
5. Infrastructure: Offices, data rooms, commercial buildings, structured cabling, smart buildings, and large engineering projects.

Choseal is a brand operated under several legal entities. The principal operating company is Shenzhen Choseal Industrial Co., Ltd. The broader corporate group is known as the Guangdong Qianhai Choseal Group, which operates two principal brands: Choseal/秋叶原 and Mengke Park/梦科园. The group’s activities extend into industrial parks and technology-oriented services.

As of current information, the headquarters is located in Bao’an District, Shenzhen, Guangdong, China. The specific facility is identified as Zhongliang Chuangzhi Factory Zone 67, Xin’an, Bao’an District, Shenzhen. Manufacturing bases are located in Huizhou, Guangdong and Shanwei, Guangdong. The Huizhou operation has historically been central to its manufacturing infrastructure.

Choseal is best understood as a long-established Chinese connectivity manufacturer and brand, rather than a luxury electronics label. Its competitive advantage lies in combining manufacturing, a large product range, engineering experience, distribution, and consumer e-commerce. This allows it to sell inexpensive consumer cables (¥10–¥50 range) while also participating in larger structured-cabling or AV projects.

Industry Recognition

The company has accumulated various Chinese industry and corporate recognitions, including:

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

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

These citations indicate that Choseal products were used in these projects, though not necessarily every cable component.

In addition to its engineering and distribution business, Choseal maintains a substantial presence in Chinese e-commerce. Sales channels identified by the company include Tmall, JD, Pinduoduo, and Douyin/TikTok-related channels. 7 Its JD storefront features a broad selection of networking, HDMI, USB, and other connection products.

If summarized concisely: Choseal (秋叶原) is a Chinese connectivity and cable brand founded in 1989, headquartered in Shenzhen, whose product portfolio spans consumer AV and digital cables, Ethernet and structured cabling, professional audiovisual equipment, security infrastructure, and intelligent engineering connectivity. 9 The brand represents a comprehensive ecosystem of cable and connection solutions rather than a single type of product. 10
