Parallel dual bluetooth headphone audio test
With the continuous development of the 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.
