Bose has sold aviation headsets since 1989 and consumer headphones since 2000.[1] The current range of headphones/headsets consists of over-ear, in-ear, aviation and military models.

Over-ear headphones[edit]

Development of the company's noise-cancelling headphones (and first over-ear headphones) began in 1978 when the chairman, Amar Bose, tried a set of airline-supplied headphones during a flight and found that engine noise from the aircraft prevented the music from being enjoyed.[2]

In 1986, Bose and Sennheiser both presented active noise-cancelling headsets for aircraft pilots, with the Sennheiser design appearing in a Funkschau (see Funkschau article on the German Wikipedia) paper and the Bose design appearing in an ASME paper.[3] A prototype Bose product was used to prevent hearing loss in pilots during the first non-stop around-the-world flight in the Rutan Voyager.[1] The company was the first to release active noise cancelling headphones as a consumer product.[4]

QuietComfort 25[edit]

The "QuietComfort 25" (QC25) over-ear headphones were released in 2015[5] as the replacement for the QuietComfort 15. Unlike its predecessors, the QC25s can be used (without the noise-cancelling function) while the battery is flat. Another change is the elimination of the Hi/Low switch which increased the input gain for low-output sources like MP3 players.

In 2014, the QC25s won the What Hi-Fi? Sound and Vision annual award for "Best Noise Cancelling Headphones".[citation needed]

QuietComfort 35 II[edit]

QuietComfort 35 II

The "QuietComfort 35 II" (QC35 II) over-ear wireless headphones were released in 2017[6] as the replacement for the QuietComfort 35. Compared with its predecessor, the QC35 II has a Google Assistant button, which allows the user to speak instructions to the Google Assistant on Apple or Android devices.[7]

The QC35 IIs were reviewed favourably for their noise cancellation, audio quality and comfort.[8][9][10][11]

Noise Cancelling Headphones 700[edit]

The "Noise Cancelling Headphones 700" is the successor to the QuietComfort 35 II.[12] It is released on June 30th, 2019.[13]

In-ear headphones[edit]

QuietComfort 20[edit]

The "QuietComfort 20" (QC20) and QC20i in-ear headphones were released in 2015 and are the company's first in-ear noise cancelling headphones.[14] The QC20 model is for Android, Android, Windows and Blackberry devices, while the QC20i is designed for Apple devices and includes volume controls on the remote.[15]

The noise-cancelling hardware and rechargable battery is contained with a box located near the headphone jack, similar to the QuietComfort 15. The earbuds are similar to the IE2 headphones. A button on the remote labelled "Aware Mode" reduces noise-cancellation to let in ambient noise.

Industrial headphones[edit]

A20 Aviation Headset[edit]

The "A20 Aviation Headset" was released in 2010 as the successor to the "Aviation Headset X" (aka A10).[16][17] It has a claimed battery life of 45 hours (using two AA batteries) or can be powered by the airplane's electrical system. There are two versions, one with Bluetooth and one without.[18]

An updated version of the A20 was released in 2015.[19]

Combat Vehicle Crewman Headset[edit]

A "Combat Vehicle Crewman Headset" was released in 1998, for use in armoured vehicles.[20]

Triport Tactical Headset[edit]

A "Triport Tactical Headset" (TTH) was released in 2004.[21] It is designed for use in armoured vehicles and can fit under an infantry ballistic helmet.[22][23] An updated version was released in 2012.[24]
