What It Is

grandsun.com is the official website of Shenzhen Grandsun Electronic Co., Ltd. According to the website, the company was founded in 1997 and is headquartered in the International Low Carbon City, Pingdi, Longgang District, Shenzhen. It specializes in the R&D, manufacturing, and brand marketing of smart terminal products such as professional audio, smart headphones, and smart speakers. The website itself is not an e-commerce store, but rather a corporate portal and business cooperation gateway.

Core Features

The official website primarily offers modules such as product overview, news center, about us, sustainability, join us, and contact information. The product focus is on smart headphones and smart speakers. The headphones cover open-ear, true wireless, neckband, and over-ear form factors, and showcase Cleer-related products like the ARC series. The company profile emphasizes its long-term partnerships with international brand owners, chipmakers, platform solution providers, and cloud service providers, as well as its global layout encompassing R&D, manufacturing, and brand sales centers.

Pricing

The website does not disclose retail prices, ODM/OEM quotes, minimum order quantities (MOQs), delivery lead times, or after-sales policies. Procurement, group purchases, investment promotion, and overseas business all require manual communication via the contacts, phone numbers, or emails listed on the page, making it more of a project-based business cooperation model.

Pros & Cons

Pros: Clear corporate background with a long history, covering R&D, manufacturing, and brand marketing. It publicly highlights products winning design awards like CES, ISE, German Red Dot, iF, and Good Design. Contact methods are categorized into business cooperation, corporate gifting, investment promotion, and overseas business, facilitating easy connection for different partners. The site also features ESG, environment, social responsibility, and corporate governance sections, showcasing awareness of compliance, privacy, information security, and anti-bribery management.

Cons: The website is relatively static, lacking procurement-critical information like product specs, chip solutions, acoustic metrics, certifications, mass production capacity, and client case studies. It also lacks online inquiry, resource downloads, after-sales tracking, or online purchasing features. Some product details redirect to the Cleer website, making the information flow less centralized.

Who It's For

Suitable for brand owners, distributors, corporate gifting clients, investment partners, and overseas audio business clients looking for R&D and manufacturing partnerships for smart headphones and smart speakers. General consumers looking to purchase specific headphone products may need to turn to the Cleer brand channels.

Access from China

This is an ICP-registered domestic website (registration number: 粤ICP备17044769号-1), offering Simplified Chinese and English portals for Chinese-speaking users. It is expected to be directly accessible from mainland China.
