1. Wireless earphone
Wireless earphone is a device that allows you to listen to audio or make calls without wires or cables. There are three common types of wireless earphones: Bluetooth, infrared and RF (radio frequency).
2. Preparing for global market access
We provide full compliance testing for prototype or finished electrical/electronic products, and also obtain regulatory certifications recognized both domestically and internationally. Our goal is to certify your products and ensure their compliance with regulatory standards in order to help you access worldwide markets.
