How Bluetooth Headphones Work?

For businesses around the world, staying connected has never been more important. The rise of hybrid and remote work has necessitated an increase in the frequency of team meetings and conversations via online meeting software. 

Having the equipment to enable these meetings to run smoothly and keep the lines of communication open is critical. For many people, that means investing in quality Bluetooth headphones. 

Unsurprisingly, a bluetooth headset is a headset that provides a hands-free experience when connected to your computer or phone setup via bluetooth. Audio from your device is played through the wireless headset, which also transmits your voice responses. 

For those who provide customer service in contact centers or spend a lot of time in online meetings, Bluetooth headsets can be a game changer.

They can come in a variety of styles and with different features, from noise-canceling headphones to headphones with a charger or charging case, and even true wireless earbuds. The intended use of the headset will influence which features and quality you prioritize.

For example, those who use a Bluetooth headset for hours on a business phone system will be looking for a headset that captures sound clearly and is comfortable to wear for extended periods of time. 

Bluetooth is no longer a new technology and can be used to wirelessly connect laptops and Macs, iPhones and other smartphones, Sony Bluetooth speakers, scanners, microphones, Samsung tablets, Sennheiser sound bars, printers, keyboards, and even wireless headphones. 

It eliminates the need to use restrictive wires to transfer files, sounds, and audio to other devices. This wireless setup is great for engaging in long calls, especially when working remotely.

Bluetooth devices work in localized networks, which means they must be within range of the device you want to connect to. A Bluetooth connection uses radio waves to create a wireless signal between devices and is configured using an algorithm to determine the frequency with the least interference with other similar wireless signals. 

Configuring in this way means that all audio should be clear on both ends of transmission and reception. 

In order for your Bluetooth headset to transmit your voice and receive audio signals, a parent device is needed to build the Bluetooth network—usually your computer or phone. 

The parent device can connect to up to seven other Bluetooth devices at the same time and communicate with them individually (though no other devices can communicate with each other). The parent device creates the signals to be sent across the Bluetooth network and receives audio input from its Bluetooth connection. 

Pairing your Bluetooth headset is the term used to connect it to the parent device. Once paired, devices can create transmissions and receive signals from each other. Using a Bluetooth headset changes the speaker and microphone used by the parent device to the speaker and microphone in the headset for dialing into conference calls, watching videos, or recording. The parent device creates and stores a list of previously paired devices for future reconnection. 

To pair your devices, both need to have Bluetooth turned on and their devices set to be discoverable. These options can usually be found in your device or connection settings. When pairing for the first time, the device may ask you to enter the wireless headset password and PIN to activate and authorize the connection; however, the parent device will remember this information for future use. 

While they occasionally require charging, the operation of Bluetooth devices consumes the least amount of power. By using short-range signals and frequencies, Bluetooth uses very little power to transmit and receive between devices. This means that you can easily rely on the Bluetooth headset to extend battery life without draining it during a call.

This does limit the possible distance between the parent device and the wireless headset, as short-range signals reach around 60 meters. Using higher transmit power will increase your range at the expense of using more power. For remote workers, this isn't usually a big deal, as being in line of sight of your parent device while on a call isn't usually a challenge.

Different wireless headphones use different methods to minimize noise and interference with sound quality. Noise-cancelling technology has been employed to make the audio transmission from the microphone as clear as possible to improve sound quality. With dual-microphone technology, the headset recognizes your voice and eliminates background noise from the microphone during video conferences or calls.

Technology has also been developed to improve audio reception through headphones. Traditionally, this has involved using over-ear headphones to reduce external noise for wireless headphone users. Recent technological developments have studied bone conduction, which instead of sending audio signals to your ears, uses sound vibrations that pass through the user's temples to provide a clearer connection. 

No matter what you want to use your Bluetooth headphones for - from remote calls, listening to music or podcasts on the move, or minimizing background noise, there's one for you. Although they all use Bluetooth in the same way and share some of the same advantages, there are so many earphones to choose from, each with different features and styles of wireless earphones for every purpose.
