The name Bose QuietComfort Ultra refers to several products: over-ear headphones, wireless earbuds and a range of colour finishes. This lineup is designed for adults and teenagers aged 14 and over, whether they want to listen to music, work, travel or watch films in noisy environments.
Some marketing claims nevertheless deserve a closer look. Active noise cancellation does not eliminate every sound, spatial audio can reduce battery life, and a splash-resistant product is not designed to be submerged. Here are the key points to check before choosing Bose QuietComfort Ultra headphones or Bose QuietComfort Ultra earbuds.
The Quiet, Aware and Immersion modes are designed for different situations. Quiet activates a high level of noise cancellation, while Aware allows more surrounding sound through. Immersion combines active noise cancellation with spatial audio.
The result depends on the frequency of the noise, the product’s positioning and the isolation provided by the ear cushions or ear tips. On public transport, over-ear headphones also benefit from passive isolation thanks to their cushions. Earbuds, by contrast, depend more heavily on how well they fit inside the ear canal.
Advertised battery life varies depending on the mode in use. The Bose QuietComfort Ultra Headphones 2nd Gen offer up to 30 hours in Quiet or Aware modes, but this drops to 23 hours when Immersive Audio is enabled. The earbuds provide up to 6 hours per charge, with total battery life of up to 24 hours when combined with the charging case, depending on the version.
Fast charging can help offset more limited battery life. The 2nd-generation headphones provide up to 3 hours of listening after 15 minutes of charging, while certain earbuds can recover up to 2 hours of playback after just 20 minutes.
Even a premium headset loses much of its appeal if it applies excessive pressure after a few hours. Earbuds, meanwhile, need to stay securely in place while walking or exercising. Check whether the package includes several ear-tip sizes and stabilising bands.
The 2nd-generation QuietComfort Ultra earbuds carry an IPX4 rating. This guarantees resistance to splashes and perspiration, but it does not mean the product can be immersed in water. The over-ear headphones in the range, meanwhile, should not be exposed to moisture.
According to Bose, CustomTune adapts the sound profile and noise cancellation to the shape of your ears. It is a personalisation feature that must be configured in the Bose app, not a guarantee that every user will achieve exactly the same result.
For daily commuting, compare the physical or touch controls, how easily you can switch between Quiet and Aware modes, and whether you can create custom modes. In situations where you need to remain alert, such as on the street or at a train station, Aware may be more suitable than maximum isolation.
Bose Immersive Audio positions the sound in front of the listener instead of making it seem as though it comes solely from inside the head. The 2nd-generation headphones also add a Cinema mode designed for video content, with a stated balance between dialogue, effects and ambient sound.
This feature can be especially engaging for films and certain tracks, but it consumes more power. If long battery life is your priority at the office, compare standard-mode playback with the runtime achieved using Immersive Audio.
Recent models support Bluetooth and, depending on the version, multipoint connectivity. This allows you to pair two compatible devices — such as a computer and a smartphone — and switch between them more easily.
The 2nd-generation Bose QuietComfort Ultra headphones also support wired listening via USB-C with lossless audio, according to the information supplied with the product, as well as audio connection through a 3.5 mm-to-2.5 mm cable. Microphones equipped with environmental noise reduction can improve voice clarity during calls, but quality also depends on the connection, wind and ambient noise levels.
Why this model is a good fit: These over-ear headphones are well suited to listening at home, working remotely and daily commuting, particularly if you appreciate a full-size design and a white finish.
Quiet, Aware and Immersion modes are clearly differentiated. The stated battery life also distinguishes between listening with ANC and immersive listening, giving you a more realistic idea of expected runtime.
Up to 24 hours according to the product listing, around 2 hours 30 minutes of listening after a 15-minute fast charge, plus Bluetooth 5.3 connectivity with a 2.5 mm jack.
Why this model is a good fit: Designed for those looking for premium headphones for long journeys, work and films, with personalisation features and wired listening support.
The product information distinguishes 30 hours in Quiet or Aware modes from 23 hours with Bose Immersive Audio. Cinema mode is also listed separately for video content.
Bluetooth 5.4, multipoint, USB-C with lossless audio listed in the product information, CustomTune and a 15-minute fast charge providing up to 2 hours 30 minutes of listening.
Why this model is a good fit: The true wireless design slips easily into a pocket, while the stabilising bands are well suited to commuting and moderate-intensity activities.
The IPX4 rating is clearly stated without being presented as full waterproofing. Quiet, Aware and Immersion modes let you adapt listening to your surroundings.
Up to 6 hours per charge, up to 24 hours with the case, Bluetooth multipoint, calls using a single earbud and a 20-minute fast charge for 2 hours of listening.
We have brought together an up-to-date selection of products matching these criteria, with a range of versions and finishes.
Before listening for the first time, charge the device using the supplied USB-C cable. A power adapter is generally not included. Then enable Bluetooth on your smartphone, tablet or computer and select the product name.
The Bose app guides you through setup, lets you adjust the equaliser, create custom modes and install updates. For the earbuds, try several combinations of ear tips and stabilising bands to find a secure yet comfortable fit.
Clean the headphones with a soft, dry cloth. Do not use any liquids and never attempt to disassemble the integrated battery. Prolonged listening at high volume can damage your hearing: keep the volume at a moderate level, particularly for users aged 14 to 17.
Yes. Versions compatible with multipoint can be paired with two Bluetooth devices. This is useful when switching between a work computer and a phone, subject to device compatibility and the settings in use.
This depends on frequency of use, storage conditions, maintenance and the condition of the rechargeable battery. Ear cushions and ear tips are consumable components. Avoid heat, excessive moisture and impacts. If the battery swells, the cable is damaged or the casing is cracked, stop using the product and contact the after-sales service.
Over-ear headphones provide enveloping ear cushions, generally longer battery life and greater comfort for extended listening sessions. Earbuds are more discreet and easier to carry, but their fit needs to be chosen carefully. Ultimately, the right design depends on your comfort, your commute and how much isolation you need.
