I use headphones all the time, both earbuds and headsets alike, since they let me listen to music without others hearing.
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
Headphones (or head-phones in the early days of telephony and radio) 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 earspeakers, earphones or, colloquially, cans. Circumaural and supra-aural headphones use a band over the top of the head to hold the speakers in place. The other type, known as earbuds or earpieces consist of individual units that plug into the user's ear canal.

Hearables
Hearables or Smart headphones are technically advanced, electronic in-ear-devices designed for multiple purposes ranging from wireless transmission to communication objectives, medical monitoring and fitness tracking. Hearables are therefore a manifestation of the concept of ubiquitous computing. The neologism "hearable" is a hybrid of the terms wearable and headphone, as hearables combine major assets of wearable technology with the basic principle of audio-based information services, conventional rendition of music and wireless telecommunication. The term was introduced in April 2014 simultaneously by Apple in the context of the company's acquisition of Beats Electronics and product designer and wireless application specialist Nick Hunn in a blogpost for a wearable technologies internet platform.
Headset (audio)
A headset combines a headphone with a microphone. Headsets are made with either a(n) single-earpiece (mono) or a(n) double-earpiece (mono to both ears or stereo). Headsets provide the equivalent functionality of a telephone handset but with handsfree operation. They have many uses including in call centers and other telephone-intensive jobs and for anybody wishing to have both hands free during a telephone conversation. Telephone headsets generally use 150-ohm loudspeakers with a narrower frequency range than those also used for entertainment. Stereo computer headsets, on the other hand, use 32-ohm speakers with a broader frequency range.
Bose headphones
Bose Corporation produces headphones for consumer, aviation and military use. The models range includes in-ear headphones, mobile headsets, supra-aural headphones, Circumaural headphones and military/aviation headsets. The company was the first to release active noise cancelling headphones as a consumer product. Bose's consumer range of active noise-cancelling headphones are called "QuietComfort". For industrial noise-cancelling applications, Bose produces the A20 Aviation Headset, Space Shuttle Headset and Combat Vehicle Crewman Headset. According to Bose, the company started noise-cancellation involvement after Dr. Amar Bose went on a 1978 flight to Europe, and "was trying out new set of airline-supplied headphones and found that he couldn't really enjoy the sound with the roar of engines in the background".
IPhone
iPhone ( ) is a line of smartphones designed and marketed by Apple Inc. They run Apple's iOS mobile operating system. The first-generation iPhone was released on June 29, 2007, and there have been multiple new hardware iterations with new iOS releases since. The user interface is built around the device's multi-touch screen, including a virtual keyboard. The iPhone has Wi-Fi and can connect to cellular networks. An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive email, browse the web, send and receive text messages, follow GPS navigation, record notes, perform mathematical calculations, and receive visual voicemail.
In-flight entertainment
In-flight entertainment (IFE) refers to the entertainment available to aircraft passengers during a flight. In 1936, the airship "Hindenburg" offered passengers a piano, lounge, dining room, smoking room, and bar during the 2 1/2 day flight between Europe and America. After the Second World War, IFE was delivered in the form of food and drink services, along with an occasional projector movie during lengthy flights. In 1985 the first personal audio player was offered to passengers, along with noise cancelling headphones in 1989. During the 1990s the demand for better IFE was a major factor in the design of aircraft cabins.
