With the continuous development of electronic technology, headphones have experienced the development from wired to wireless ones. As the market share of Bluetooth headphones is getting higher and higher, their quality inspection is becoming more and more important. The traditional single Bluetooth test solution is slow and inefficient. Our TWS single-head Bluetooth parallel dual-testing solution has such characteristics as fast test, simple operation and fewer active device channels. It is the leading efficient solution in this industry.
Parallel dual Bluetooth test
- Place two TWS single-head receivers into the left and right shielding boxes respectively for testing
- Bluetooth connection, Bluetooth SPK test, and Bluetooth MIC test are the same as the general single test
- The left and right shielding boxes are completely independent and independent tests can be performed simultaneously
- UPH can be twice as much as the previous one
