Wireless devices
Provide all kinds of wireless product equipment testing certification
Wireless electronic products are more suitable for use on the occasion of many people, in the real society is used more, used more widely, the product has a plastic shell and metal interior, in real life when buying products, we will choose to buy the safe, reliable, durable, environmental protection products on the market.Electronic and electrical products with a wireless module that can transmit and receive data in a certain frequency band.
Wireless headphones are the middle wire replaced by radio
waves, which are connected from the audio outlet of the computer to
the transmitter, and then sent by radio waves from the transmitter
to the receiver of the headset, which is equivalent to a radio.
Wireless headphones are becoming so common that they are almost
replacing wired headphones. That's because wireless headphones are
easier to use, prettier to look at, and, as technology changes,
better sound quality.

Export of wireless earphones to the EU must pass CE certification.
In the European Union, wireless headsets must comply with various
directives, in particular the EMC Directive and the Radio Equipment
Directive (RED). These directives define a number of technical
requirements.
Radio modules built into radio products must comply with the
relevant instructions and be marked by the module manufacturer in
accordance with the instructions and bear the CE mark. Therefore,
it is not sufficient for the final wireless headset to have a CE
mark, and the module installed must have its Conformance Statement
(DoC) and CE mark.
RED includes radio performance for all devices that contain radio
functionality, transmitters, or receivers
EMC performance and product safety (including RF exposure)
assessment.
Module manufacturers must perform all of the above tests on their headsets and then formulate a compliance declaration and CE mark. The CE mark for a radio module is the manufacturer's statement that the radio module complies with the RED Directive. The radio module installation instructions and DoC describe the conditions under which this applies. In addition, specific equipment is required to obtain an EU type Inspection Certificate from the EU Notification body before being placed on the market. In these cases, the EU type Inspection certificate is a prerequisite for the development of a valid declaration of conformity; Only type inspection certificate is not product approval document. To put a radio product on the market, it is not enough that the installed radio module has DoC and CE marks. The entire product itself serves as a transmitter product and also meets RED safety requirements. The manufacturer of the final product is solely responsible for drafting the compliance statement and labeling the final product with the CE mark.
