I. Introduction to Audio Certification Products
Wireless speakers include: Bluetooth wireless speakers, wifi wireless speakers, 2.4G wireless speakers, FM wireless speakers, etc. From the early low-cost FM wireless speakers and high-cost 2.4G wireless speakers to Bluetooth wireless speakers and wifi wireless speakers, Bluetooth wireless speakers have been widely accepted by consumers for their price, anti-interference effect, sound quality, portability and popularity. Most of the speakers on the market are Bluetooth wireless speakers.
