By the time you finish reading this article you will understand how do the Wireless Headphones works and what are the best product you can purchase depending on your needs.
How do Wireless Headphones work?
When you turn on your already paired Wireless Headphones or Earbuds, a Bluetooth connection channel is established in order to send information back and forth. As soon as you start playing music, your smartphone grabs the auto data from its flash storage chip, decompresses the audio and stores it in your phone’s working memory.
The audio is represented digitally as a long set of digits, and in order to send it to your Wireless Headphones, your smartphone compresses and divides the information into packets, according to Bluetooth specifications.
Next, your smartphone converts these packets into electromagnetic waves and sends the data to the headphones over Bluetooth connection. The headphones or earbuds, receive the data and disassemble and decompress the packets into long sets of values. These values are then sent to the Audio Codec, which converts the digital values into an analog electrical waveform.
This waveform is sent to the voice coil, which is attached to the back of the diaphragm. The voice coil moves back and forth, depending on the given waveform, thus moving the diaphragm which in turn creates pressure waves in the air. These pressure waves are sensed by your ear and interpreted as sound by your brain.
Are Wireless Headphones safe for health?
There are a lot of questions about the amount of the health risk that the Wireless Headphones may cause but let me say that there is no identified risk yet. The amount of the radiation that comes out from these devices isn´t something that is going to potentially cause long-term damage. Honestly, by having your smartphone to your ear , you are going to potentially have more radiation to your head area then you will with a Wireless Headphones.
