Wireless headphones.

Headphones are a pair of small loudspeaker drivers worn on or around the head over a user's ears.

They are electroacoustic transducers, which convert an electrical signal to a corresponding sound.

Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear.

Headphones are also known as earphones or, colloquially, cans.

Circumaural ('around the ear') and supra-aural ('over the ear') headphones use a band over the top of the head to hold the speakers in place.

Another type, known as earbuds or earpieces consist of individual units that plug into the user's ear canal.

A third type are bone conduction headphones, which typically wrap around the back of the head and rest in front of the ear canal, leaving the ear canal open.

In the context of telecommunication, a headset is a combination of headphone and microphone.

Two decades of evolution of mobile phones, from a 1992 Motorola 8900X-2 to the 2014 iPhone 6 Plus.

A mobile phone (cellphone, etc) is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area, as opposed to a fixed-location phone (landline phone).

The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN).

Modern mobile telephone services use a cellular network architecture and therefore mobile telephones are called cellphones (or "cell phones") in North America.

In addition to telephony, digital mobile phones support a variety of other services, such as text messaging, multimedia messagIng, email, Internet access (via LTE, 5G NR or Wi-Fi), short-range wireless communications (infrared, Bluetooth), satellite access (navigation, messaging connectivity), business applications, video games and digital photography.

Mobile phones offering only basic capabilities are known as feature phones; mobile phones which offer greatly advanced computing capabilities are referred to as smartphones.

Technology is the application of knowledge for achieving practical goals in a reproducible way.

The word technology can also mean the products resulting from such efforts, including both tangible tools such as utensils or machines, and intangible ones such as software.

Technology plays a critical role in science, engineering, and everyday life.
