Bluetooth is a wireless technology standard developed by telecommunications company Ericsson in 1994. It uses short-wavelength ultra high frequency (UHF) radio waves in the ISM band (2.4 to 2.485 GHz) to allow the transmission of all kinds of data over short distances.
Since its inception, Bluetooth has enjoyed mainstream popularity across the globe, with an estimated 10 billion Bluetooth-enabled devices in the world by the end of 2018. One of the most common uses of Bluetooth is connecting audio devices such as headphones to a smartphone or a laptop, which enables the user to listen to music or watch movies without the hassle of wires.
If you have wireless Bluetooth headphones but are not sure how to connect them to your MacBook, don’t worry. It’s a simple process that will be detailed in this blog. So read on.
Using Bluetooth headphones with your MacBook
The first thing you need to do is read the manual of your audio device to see if it’s safe to pair with a laptop. When you’ve determined that it’s compatible with your MacBook, follow these steps to pair them:
- Click on the Apple menu on the top-left corner of your screen and then select System Preferences from the drop-down menu.
- Click on Bluetooth to make your MacBook discoverable.
- Turn on your Bluetooth headphones and wait a few seconds for them to be detected by your MacBook.
- Select the device from the list that appears on your screen.
- Click on Pair.
- Click on Accept if a prompt appears on-screen.
You will only have to do this once. Your Bluetooth headphones will remain paired to your MacBook unless you unpair them. To unpair any device from your MacBook, simply Control-click on the device’s name.

Using Bluetooth headphones with your iOS devices
You can also pair your Bluetooth headphones with any iOS devices you may have. Just follow these instructions.
- Turn on your Bluetooth headphones and make sure they’re in discovery mode.
- Go to Settings on your iOS device, then tap on Bluetooth.
- Turn on Bluetooth by tapping on the slider.
- Wait for your Bluetooth headphones to get detected by your iOS device.
- Tap your Bluetooth headphone’s name once it appears on screen.
You can now start using the Bluetooth headphones with your iOS device. If you want to pair multiple Bluetooth headphones or other wireless accessories, all you need to do is repeat the process stated above.
Any Bluetooth peripherals paired with your iOS device will stay that way unless you unpair the specific device.
Is using Bluetooth safe?
Just like cellphones or smartphones, Bluetooth devices emit microwave radiation, albeit to a much lesser degree. Right now, regulatory bodies don’t consider Bluetooth radiation harmful, as its levels are too low to be dangerous.
Since the effects of this radiation to the human body are still being studied, there is no clear-cut statement yet from the scientific community whether Bluetooth radiation is safe or harmful.
However, there seems to be growing evidence with points to biological harm caused by the radiation from Bluetooth devices. There is research that suggests that long-term exposure to Bluetooth radiation is linked to several conditions, which include:
- Brain diseases
Since Bluetooth accessories, especially audio devices like earbuds and headsets, are placed in proximity to the head, scientists believe that long-term exposure can lead to neurological disorders such as brain tumors, multiple sclerosis, and Alzheimer’s.
As far as current data goes, radiation emitted by Bluetooth devices is too low to be cancerous to humans. According to experts, cellphone and smartphone radiation is much more likely to cause cancer. Some argue, though, that over a long period of time, this small amount of radiation can still cause many different kinds of cancer.
- Other negative effects
Researchers believe that long-term use of Bluetooth devices are also to blame for a variety of minor health problems such as hair loss, headaches, neck pain, ear pain, and even skin rashes.
As of now, there is still little concrete evidence to definitively say that Bluetooth devices are harmful, so you can keep using your wireless accessories for as long as you choose. Just keep in mind that if you feel any pain or discomfort in your body that you think is related to your use of any Bluetooth device, seek professional medical help by setting an appointment with your doctor as soon as possible.
