To ensure the "true" performance of each TWS earphones, each earphones must be tested in production. If the data learned by the appeal can know that the annual shipment of TWS earphones is huge, so how to measure the production test?

01. What needs to be tested are several major key indicators of the Bluetooth earphones, including transmission power, frequency offset, reception sensitivity, etc.

02. Select the typical channels for testing.

03. Most earphones do not have an RF test connection port, so they should be tested through OTA.

04. Need to choose a cost-effective (economical, fast, accurate) test scheme.
