How do Wireless Bluetooth headphones work ? Wireless Bluetooth headphone works solely with the help of radio waves instead of wires or cables.

Bluetooth equipped headset can be connected to your cell phone, computers or your smartphones.

Bluetooth systems create a personal-area network (PAN), or piconet, and that network is of very short range (Usually few feets). Bluetooth sends and receives radio waves on a frequency band of 2.45 GHz within its piconet and hence the communication happens.

They use virtually no power and, because they don’t travel far, are theoretically more secure than wireless networks that operate over longer ranges, such as Wi-Fi.

Bluetooth devices automatically detect and connect to one another and up to eight of them can communicate at any one time (because they use different channels/frequency ranges). Lets dive deeper into this.


What is a Bluetooth?

A Bluetooth is a wireless short-range communication technology that is nowadays found in mostly all electronic products that we use in everyday life. They are found in headsets, phones, laptops and portable speakers.

A Bluetooth headphone comprises Bluetooth technology. It has a tiny computer chip that contains a blue tooth radio and software that helps devices connect to each other. Bluetooth enabled products pair up with each other if they are in close proximity – called as personal-area network (PAN), orĀ piconet – to each other and turned on.

A single Bluetooth headphone can connect to various devices at a single point in time because of they communicate through different channels (A band of 79 different frequencies). Thus listening to music, speaking on the phone from a distance and performing other activities with your hands-free.

The technology in the headset is safe and high quality and many people are nowadays seen to be using it while traveling, driving or working on something.

So how do wireless bluetooth headphones work?

The Bluetooth headphones require a parent device to pair with – which is your phone. A Bluetooth headset, which is connected, becomes a part of a specialized wireless network of your smartphone.

The headphone acts as a transmitter and the receiver of the wireless signal.

The radio waves are configured in a complex algorithm so that you can hear clearly. The headphone allows clear transmission of sounds and clear speech through your microphone.

So by sending radio waves aka frequencies within its piconet, wireless headphones connect and works with your smartphone.

Pairing the device

A Wireless Bluetooth headphone needs to be paired with the phone in order to transfer information. Both the devices must have Bluetooth pairing turned on and be set at a mode where both are visible to each other.

Bluetooth headphones have a password PIN number that can be entered into the phone to activate the pairing. This makes it safe and protected from intruders.


Battery life is very significant for a blue tooth headphone. The Wireless Bluetooth headphones, however, require very less power to operate as they are of less frequency and shorter ranges.

The low power nature also limits the distance between the headphone and the device. If the two devices are far away from each other, then the Bluetooth gets disconnected.

The maximum distance that can be covered by a headphone and the parent phone is approximately 164 feet. Nowadays Bluetooth devices require even lesser power because of technology.

Headset technology

The signal quality of sound in Bluetooth connection is pretty good. The better the microphone and earpieces, the better would be the sound quality. Sound qualities can also improve, based on the bluetooth.

How to use wireless Bluetooth headphones and pair with another device

  • Start with your headset in the power off mode
  • Press and hold the power button for a while until the light starts flashing and the headset is turned on
  • Release the button and set the headset aside
  • Follow the pairing instruction with your device
  • Once the instruction for pairing appears, search and then press ok.
  • Your Bluetooth headphone is now paired with your device
  • Listen to music, see movies and also speak on the phone with the help of the Bluetooth headphone.

So we hope now you have idea about How do Wireless Bluetooth headphones work.
