Basically, all Bluetooth headsets are wireless, but not all wireless headsets use Bluetooth technology. Wireless headphones transmit sound through low-power radio signals, taking the cord out of the product. This process requires two devices: one that acts as a transmitter (like a smartphone) and one that acts as a receiver (like a headset or speaker).
While both types of headphones work via a wireless connection, their fundamentals are different. The main difference is how the headphones connect to the source.
Bluetooth headsets transmit audio signals using short-range radio waves that are Bluetooth technical specifications, while other wireless headsets can use RF radio waves, infrared, KleerNet wireless signals, or even SD cards.
1, Radio frequency (RF) wireless: One of the most stable wireless technologies for connection, RF wireless headphones transmit sound through a specific radio wave frequency.
2, infrared (IR) wireless: stable high quality short distance. Infrared (IR) wireless headphones, as the name suggests, use infrared technology to transmit audio signals, similar to TVS and air conditioning remote controls in the home.
3, storage wireless: is a headphone player.
4, AM\/FM wireless: radio type wireless headphones. In fact, that's how the world's first wireless headphones worked.
