1. Raw material procurement

First, we need to purchase various raw materials from all over the world, including sound transmission components, electronic components,
plastic materials, etc. These raw materials need to undergo strict quality testing to ensure that they meet the factory's production standards.

2. Design and R&D of headphones

After purchasing the raw materials, the factory’s team of designers and engineers will begin the design and development of the headphones.
They make repeated modifications and improvements based on market demand and user feedback to ensure that the performance, comfort
and appearance of the headphones are optimal.

3. Production and processing

After the design is completed, the factory will begin production and processing. This process includes injection molding of plastic materials,
processing of sound transmission components, assembly of electronic components, etc. Every link needs to undergo strict quality testing to
ensure product quality and stability.

4. Quality inspection

After production and processing is completed, each headset needs to undergo strict quality inspection. This process includes sound testing,
durability testing, functional testing, etc. Only headphones that pass these tests can be deemed qualified.

5. Packaging and delivery

Finally, qualified headphones are packaged and shipped to customers around the world. Each headset comes with a professional packaging
box and accessories to ensure that users can enjoy the best experience after purchase.

Through this visit, we gained a deep understanding of the entire manufacturing process of high-quality headphones from raw material
procurement to final products. Every link needs to undergo strict quality control and testing to ensure product quality and stability. It is
precisely because of these professional and sophisticated manufacturing processes that we have the high-quality headphone equipment in
our hands.
