The Mystery Behind JL (JieLi) Audio Bluetooth Chips for 9.9 - Yuan Wireless Bluetooth Earbuds with Free Shipping

Can you believe that there are 9.9 - yuan wireless Bluetooth earbuds with free shipping? Regardless of the quality and sound quality of these earbuds, the fact that they can achieve normal operation of functions such as Bluetooth wireless connection and pairing, earbud audio playback via Bluetooth, and charging case charging at such a low price is undoubtedly an ultimate manifestation of cost - effectiveness and a miracle of Made in China. Now, let's explore the core of these earbuds - JL (JieLi) Audio Bluetooth Chips, and find out what advantages they rely on to help Bluetooth earbud manufacturers achieve this.

1.High - integration Design：JL (JieLi) Bluetooth chips adopt a highly integrated design, integrating multiple functional modules into a single chip. Some chips have a rich built - in driver library, allowing developers to achieve functions like Bluetooth connection and audio codec without adding a large number of additional chips or modules, significantly reducing the overall hardware cost.

2.Self - developed IP Core and Local Supply Chain Cooperation：

• Self - developed IP Core：By developing its own IP core, JL (JieLi) reduces its dependence on external intellectual property, thus lowering the intellectual property licensing fees.

• Local Supply Chain Cooperation：Collaborating closely with local supply chains such as SMIC, JL (JieLi) takes advantage of the cost - advantage of the local supply chain to compress the chip cost to 60% of that of international giants, laying a solid foundation for low - cost Bluetooth earbud solutions.

3.Mature Production Process：

• Advanced Process：Some chips adopt a mature production process. For example, the KT6368A Bluetooth chip is based on a 40 - nanometer process and 12 - inch wafers, which not only improves performance but also effectively controls costs.

• Optimized Packaging：The adoption of SOP8 packaging further reduces the development and production costs for customers.

4.Cost Reduction through Mass Production：As of 2023, the cumulative sales of JL (JieLi) Bluetooth audio chips have exceeded 10 billion pieces, with a high market share. Mass production has significantly reduced the unit production cost. As fixed costs are allocated to more products, the cost per chip decreases, creating price space for low - priced Bluetooth earbuds.

5.Rapid Chip Iteration：JL (JieLi) shortens the chip iteration cycle to once every six months. By continuously launching chips with better performance and lower costs, it continuously optimizes product solutions. Each iteration has local breakthroughs, enabling better cost control while improving chip performance to meet the market demand for low - priced products.

6.Simplified Development Process：

• Abundant Development Tools：JL (JieLi) chips provide a wealth of development tools and development environments, with built - in hardware accelerators that improve the chip's computing efficiency and data processing speed, reducing the system cost.

• Shorter Development Cycle：Developers can carry out product development more conveniently and quickly, shortening the product launch time and reducing development costs, which indirectly reduces the cost of Bluetooth earbuds using JL (JieLi) chips.

The ability to produce Bluetooth earbuds with normal functions at such a price is already an ultimate display of cost - effectiveness and a miracle of Made in China.
