What are the different types of wireless headphones?
wireless headphones include one of many technologies to prevent a conventional wire that improves the headset to the sound source. All wireless headphones use the transmitter and built -in headphone receiver to send and receive sound signals through the universe wirelessly. The three technologies used are waves of radio frequencies (RF), infrared waves (IR) and Bluetooth® technology. Let's look at them. The transmitter must be connected to the sound ports of sources, commonly a television or home entertainment center. Radio waves can pass objects and walls and ceilings. This makes RF wireless headphones suitable for use in the home or office.
Another favorable quality of RF wireless headphones is that the signal remains strong outside. For those who have terraces, swimming pools or barbecue, you can not imagine in the sun, hovering on an inflatable raft or cooking your favorite food while listening to music or television program.
One disadvantage of RF technology is that it can pick up interference from other radio waves at the same frequency zone or near it. Wireless phones, wireless networks and even electric fields radiating from home entertainment or appliances can cause static or buzzing in the background. RF transmitters are made in various frequency strips, including 900 megahertz and 2.4 Gigahertz. You may want to choose a model that uses a different band than your wireless phone. Also note that RF waves can be picked up by eavesdroppers.
Infrared (IR) wireless headphones use different technology. Rather than broadcasting radio waves, the IR transmitter uses an infrared light beam, similar to remote control, light emitting diodes (LED). IR Cosluchátka without Rdless must have a clear line of supervision of the transmitter, undisturbed furniture or people who pass between the transmitter and the receiver.The efficiency range is generally up to 30 feet (~ 10 meters) for basic models. These wireless headphones are ideally intended for use in one room within a relatively close range.
occupies a different area of electromagnetic spectrum than radio waves, the advantage of IR wireless headphones is that they do not get interference from radio waves, appliances or equipment. And while the RF transmitters combine the stereo signal for sending and rely on the headphone receiver back to stereo, IR models transmit stereo signal from the base, resulting in a better overall audio experience through a cleaner channel separation.
Because the walls block the waves of light waves, the IR signal does not leave the room, so IR wireless headphones is a good choice for compartmentized listening. If you are in the living room RF wireless headphones, you can decide that children will receive wireless headphones for their bedroom. Each can listen to their own music without signals from each otherAsked or with RF headphones. IR is also a good choice for any environment that requires privacy, such as a medical office, a courtroom or a meeting room, an infrared infrared infrared will not interfere with the surrounding equipment, ensuring that it is safe to use in places such as hospitals or on board aircraft.
Bluetooth® wireless headphones are other technologies. These headphones are made for use with mobile personal electronics. Some applications include a hands-free mobile phone, MP3 players and personal digital assistants (PDA). Bluetooth® technology creates a personal area of network (PAN), grouting equipment together for interior. Connected or network devices use radio waves to communicate with less robust radio than RF wireless headphones. This saves strength, primary for dough-run personal equipment. The result, however, is a shorter effective range, but roughly compared to an infrared without limiting obstacle. However, Bluetooth® signals may interfere withOther radio wool devices, including RF wireless headphones.
Wireless headphones of all kinds are available anywhere where electronics are sold. Prices start up to $ 20 USD (USD) reaching up to more than $ 200. Although the least expensive models may not satisfy discriminatory customers, the most expensive couple in the desired category does not always bring the best quality or sound.
