These days, you really have to hunt for a smartphone with a headphone jack.

Apple removed the standard 3.5-millimeter jack for earbuds or headphones starting with the iPhone 7, released in 2016. One Android brand left them off starting in 2012, but major player

Samsung waited until 2019 to make the leap with its Galaxy Note 10 and a set of wireless Galaxy Buds.

Now you can almost count the number of new phones with these jacks on one hand. So if you’ve been using your phone to listen to music or carry on a conversation without wireless earbuds or

headphones, it’s time to embrace Bluetooth.

Bluetooth is a short-range wireless communication technology, named after 10th century Viking king Harald “Bluetooth [Blåtand]” Gormsson, who had a blue-gray dead tooth. You may be using

this tech already if you have a wireless mouse without the separate thumbnail-size receiver that you must plug into a USB port.

Bluetooth. This short-range wireless technology standard allows two nearby devices to connect directly to each other without cables. 

NFC. Near-field communication is a short-range wireless technology that transmits data via electromagnetic induction, which creates a small, invisible burst of electricity when a magnet is

moved near a metal wire, but no battery or other electricity is involved. A special reader tracks metal tags using this technology. Generally, both the reader and the tag need to be within

about an inch and a half of one another. NFC technology is found on contactless credit cards in your wallet.

RFID. Radio-frequency identification also uses electromagnetic induction to track tags, but distances can be greater, valuable for inventory tags in retail stores and toll transponders such

as E-ZPass and TxTag. RFID uses numerous radio frequencies and is the overall technology; NFC is a subset at a specific radio frequency.

Wi-Fi. This radio signal sent from a wireless router provides high-speed internet access simultaneously to multiple devices nearby. Its range is wider than Bluetooth and can handle more

devices. The name is not a shortened form of wireless fidelity.

Most fitness trackers and smartwatches connect to your smartphone using Bluetooth. Wireless keyboards often connect to laptops and tablets via Bluetooth.

Your iPhone’s AirDrop feature and Android phones’ Nearby Share use both Bluetooth and Wi-Fi to share photos and files from smartphones with friends who have similar phones. Video game pads

and controllers communicate with their consoles through Bluetooth.

Some soundbars link with newer smart TVs via Bluetooth. The newest hearing aids connect with smartphones and smart TVs via Bluetooth.

Keyless door locks can use Bluetooth to allow your phone to open them. Travel padlocks ditch the tiny wheels of a combination lock to allow you to open them from an app on your phone. Even

smart toothbrushes that can monitor and track your brushing habits sync with your smartphone via Bluetooth. 

If you’re not plugging your smartphone into your vehicle’s USB port to use a map app for navigation or listen to a playlist via Spotify or another music and podcast streaming service, a

Bluetooth connection can accomplish the task.

But when people think of Bluetooth, they think of wireless speakers, which can broadcast your phone’s or stereo’s music at a party, or wireless headsets, which can be as small as earbuds or

as big as over-the-ear headphones. If you don’t already have a set that was included with your smartphone, you’ll need to buy it.

Be aware that sound quality can vary among the various brands of earbuds, headphones and speakers. If the devices use Bluetooth, they can be connected to any stereo receiver or smartphone

with Bluetooth.

Wireless earbuds and headphones marketed for Android smartphones range from about $10 to nearly $450. Headphones are $20 to nearly $700. Earbuds and headphones that are the same brand as

your smartphone are likely to have additional features, such as Find My Device when you’ve misplaced them.
