People looking for the Bose QuietComfort Ultra Earbuds 2nd generation usually want three things: powerful active noise cancellation, enjoyable sound and a reliable fit. However, even an expensive pair of wireless earbuds can disappoint if you only look at marketing terms. Battery claims, fit and the difference between noise cancellation and spatial audio all deserve particular attention.
The product information below is based on the stated product specifications and brand descriptions. Where Bose makes claims about performance, we identify them as claims made by the brand.
A claim such as “up to six hours” applies under certain conditions. Using Bose Immersive Audio, listening at high volume, making phone calls and maintaining a strong Bluetooth connection can all affect playback time. According to the product description, the Bose QuietComfort Ultra Earbuds (2nd Gen) offer up to six hours of playback in Quiet or Aware mode, and up to four hours with Immersive Audio.
So do not only look at the total battery life with the case. Also check:
Active Noise Cancelling (ANC) is mainly designed to reduce constant sounds, such as engine noise on a train or aeroplane. Sudden voices, car horns and other changing sounds may still be audible. A transparency mode, called Aware Mode by Bose, lets in surrounding sounds.
According to Bose’s own information, CustomTune technology adjusts the sound and noise cancellation to the shape of your ear. This is a brand claim; in practice, your experience also depends on the ear tip you choose, the seal and the shape of your ear.
An in-ear earbud may offer numerous technical features but still become uncomfortable if the tip is too large or too small. A poor seal also reduces passive sound isolation and can affect how well ANC works.
So check whether multiple sizes of ear tips and stability bands are included. The Bose QuietComfort Ultra Earbuds (2nd Gen) come with a Fit Kit containing three sizes of ear tips and stability bands. The second product description lists nine combinations of tips and bands. When buying, check which contents are listed for the version you have selected.
The Bose QuietComfort Ultra Bluetooth earbuds support Bluetooth 5.3. This is a technical connection standard, not a guarantee that every device will support the same features. Also check compatibility with your phone, tablet or laptop.
Multipoint pairing is useful for people working from home: for example, you can keep a laptop and smartphone connected and switch between music and calls. The product description states that connection to multiple devices is supported.
An IPX4 rating means that the earbuds are resistant to splashing water. This is suitable for everyday use, light rain and sweat during a walk or workout. It does not mean you can submerge them or swim while wearing them. The charging case does not automatically have the same water resistance as the earbuds.
For intensive outdoor activities, it is sensible to dry the earbuds after use and keep the case away from moisture.
Touch controls let you pause music, adjust the volume and manage calls. Consider whether you find the controls comfortable to use and whether touching them accidentally triggers actions.
Bose product information mentions microphones for calls and the reduction of wind and background noise. According to Bose, SpeechClarity technology filters background noise so that your voice is picked up more clearly. This is a claim made by the brand and does not guarantee the same call quality on every street, train or in every office.
Why it suits this profile: For anyone who wants to try true wireless earbuds without immediately choosing a model with extensive ANC and audio features.
The specifications clearly state the total battery life, multipoint and IPX4. This makes it easier to see in advance which features you are and are not buying.

Why it suits this profile: A practical choice for home workers, travellers and professionals who regularly use calls, multipoint and different sound modes.
Aware mode can let in surrounding sounds, while the case supports USB-C and wireless charging. This makes it easier to switch between work, travel and home use every day.
IPX4 splash resistance, touch controls, multipoint and microphones for calls.
We have compiled a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
Place both earbuds in the case, open the Bluetooth settings on your smartphone and select the Bose earbuds. Then use the Bose app, if available, to adjust sound modes, controls and further personalisation. First choose the right ear tips and check that both earbuds sit securely.
The stated playback time is up to six hours per full charge in Quiet or Aware mode. With Immersive Audio, the product information states up to four hours. Actual battery life depends on volume, features and usage conditions. The built-in battery is not a separately replaceable component. According to the product information, EU law provides a minimum legal guarantee of two years; this is separate from the expected technical lifespan.
Do not use ANC in situations where you need to hear traffic sounds or warnings. Aware mode can let in surrounding sounds, but always check that you remain sufficiently aware of the traffic around you. Do not use earbuds while driving, and observe local traffic regulations.
