Can the Bluetooth device name or voice prompts be customized?
Selected product platforms can support Bluetooth device-name changes, voice prompts or selected firmware configuration. Availability should be confirmed for the specific model and chipset platform before the project is approved.
What affects the manufacturing cost of TWS earbuds?
Cost can be influenced by the product platform, chipset, speaker and microphone configuration, batteries, charging case, ANC or ENC functions, branding, packaging, accessories, order quantity and project-specific requirements.
How should a TWS sample be evaluated before mass production?
Buyers should check the agreed appearance, fit, sound, microphones, Bluetooth connection, charging, functions, branding and packaging. The approved sample and confirmed project specification can then serve as references for mass production.
What quality-control steps are used for Bluetooth earbuds?
Quality control can include incoming material inspection, in-process inspection, applicable functional testing and finished-product verification according to the selected product and project requirements.
