QuietComfort

Bose has sold aviation headsets since 1989 and consumer headphones since 2000. The current range of headphones and headsets includes wireless over-ear models, true wireless in-ear models, as well as aviation and military models.

Wireless over-ear headphones

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.

In 1986, Bose and Sennheiser both presented active noise cancelling headsets for aircraft pilots, with the Sennheiser design appearing in a paper and the Bose design appearing in an ASME paper.p. 13

QuietComfort 35 II

In 2017, Bose released an updated model known as the QuietComfort 35 II, which adds a customizable "action" button on the left ear cap. By default, it is mapped to activate the Google Assistant, making it the first headphones to integrate with the service.

The QC35 II was reviewed favourably for their noise cancellation, audio quality and comfort.

In July 2019, users began to report that a firmware update to the QC35 II had inhibited the performance of the noise cancellation features. Bose stated that it had not made any changes to noise cancellation functions in their firmware. Some users performed firmware downgrades, but Bose later prevented this for security reasons. In October 2019, as part of an investigation, Bose began to allow owners within a "reasonable" proximity to the company's headquarters in Framingham, Massachusetts, to request a visit by a technician.

In 2020, Bose released the Bose QC35 II Gaming, which adds a gaming mic.

Noise Cancelling Headphones 700

In 2019, Bose released the Noise Cancelling Headphones 700, also known as the NCH 700, a new high-end product positioned above the QC 35.

The headphones have a stainless steel band and are controlled using a mix of buttons and touch-sensitive areas on the cups. Unlike the QC 35, they do not fold in half, but their ear cups can rotate for storage. The embedded rechargeable battery is not replaceable which limits the lifespan of the headphones to the life of the battery. Bose promoted improvements to sound quality, noise cancellation and voice call quality over the QC 35. The NCH 700 can also connect to two devices simultaneously, and integrate with Amazon Alexa and Siri in addition to the Google Assistant.

Noise Cancelling Headphones 700 UC

This is the same headphone as the 700 but a Bose USB Link dongle is included, supposedly enhancing sound and microphone quality. But, it is listed for a larger price.

QuietComfort 45

In 2021, Bose released the Bose QuietComfort 45 headphones. This model introduced USB-C support for more convenient and faster charging. Bose also added a fourth external microphone to enhance call quality and integrated Bluetooth 5.1 to improve wireless range and connection stability. The QuietComfort 45 maintains the excellent noise-cancellation capabilities the series is known for and offers a comfortable, ergonomic design for extended use. However, the rechargeable battery is not user-replaceable and lasts for 22 hours.

QuietComfort

In September 2023, Bose released the new QuietComfort headphones this time with no model number designation. The logo returns to the black colour of the 2 generations old QC35 II rather than the light grey of the most recent QC45. This QC model offers 10 levels of adjustable ANC and 24 hours of battery life.

QuietComfort Ultra

In October 2023, Bose released the new QuietComfort Ultra headphones, which feature a modern, more premium design. The QuietComfort Ultra enhances the listening experience with spatial audio capabilities, offering an immersive soundstage. These headphones come equipped with improved active noise cancellation, leveraging advanced algorithms for better performance in various environments. The Ultra model also includes Bluetooth 5.3, providing a more stable connection and lower latency. Additionally, the battery life has been extended, offering up to 28 hours of playback on a single charge. Similar to the QuietComfort 45, the battery is not user-replaceable.

QuietComfort SC

In May 2024, Bose released an SC bundle variation of the October 2023 QuietComfort. The headphones are identical but are bundled with a soft case (hence SC) rather than a hard shell case like all previous models had. This bundle comes at a slightly cheaper price point.

Audio sunglasses Bluetooth headphones

The Bluetooth sunglasses were released in 2019 and come in two styles – Alto and Rondo. The sunglasses have open-ear audio, UVA/UVB protection, an integrated microphone, a Bluetooth range of 9 meters, and are also AR enabled. The battery can sustain up to 3.5 hours of streaming music playback and takes up to 2 hours to charge.

True wireless in-ear headphones

True wireless headphones have no cord to keep each bud connected to each other.
