Wireless Earphone Testing & Certification

GTG Group provides comprehensive safety, EMC, RF testing and certification services to ensure your products are compliant with the relevant regulatory requirements.

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.
