What is TWS headset

TWS is the abbreviation of True Wireless Stereo in English, which means true wireless stereo. TWS technology is also based on the development of Bluetooth chip technology. According to its working principle, it means that the mobile phone connects to the main earphone, and then the main earphone quickly connects to the secondary earphone wirelessly, so as to realize the wireless separation of the left and right channels of Bluetooth. When the slave speaker is not connected, the main speaker returns to mono sound quality. TWS technology has been applied to the field of bluetooth headsets, so a new product-TWS bluetooth headset was born.

TWS headset CE certification test items

1. The CE testing standards and items required for TWS headsets include EMC testing, RF testing, SAR evaluation, and LVD testing.

2. EMC tests whether the headset conforms to the CE directive on electromagnetic compatibility standards;

3. The RF test is aimed at the test of radio communication products. Since the wireless headset uses wireless Bluetooth technology, it must meet the requirements of CE-RF;

4. SAR is the electromagnetic wave absorption ratio, which is aimed at the safety and health protection requirements of electronic and electrical products;

5. LVD test is a low voltage directive to ensure that the equipment is safe to use under low voltage conditions. The part with a charging box also needs to meet the requirements of the LVD directive.
