Bose QuietComfort Ultra: Extremely immersive and comfortable

Bose QuietComfort Ultra Review
Bose QuietComfort Ultra Review

The Bose QuietComfort Ultra Earbuds are wireless headphones designed to provide the ultimate audio experience with active noise cancellation and spatial sound, ensuring they are also highly immersive. Considering the three listening modes it supports and the ability to choose from several soft ear tips, we have no doubt that anyone could end up loving them if given the chance. With that in mind, today we will review everything they bring to the table, and at the same time point out what they do well and what they don’t.

Bose QuietComfort Ultra Review

The Bose QuietComfort Ultra headphones are a set of thick wireless headphones that certainly won’t go unnoticed in your ears, as they have quite a bold look. Each earbud weighs 7.1 grams and combines an ear fin and an ovoid-shaped mouthpiece to keep it in place. Unlike other headphones that use a cylindrical mouthpiece, this shape sits more firmly in your ears without putting too much pressure on the ear canal. Simply put, they are comfortable, very comfortable, in fact.

Compared to the last generation model, these have stability bands that extend over the top edge of the earcups to improve fit. Additionally, the package includes three pairs of stability bands, as well as three sets of ear tips of different sizes, so you’re sure to find a combination you like.

In case anyone is wondering, these headphones are IPX4 certified , so they can handle some moisture, enough to withstand sweat, splashes, and light rain, but not enough to withstand submersion.

To physically control the headphones we can use the touch panels on the sides . Naturally, we can perform different actions depending on the movement we make on them. For example, swiping up increases the volume, while swiping down does the opposite. Likewise, tapping once pauses/resumes music or answers calls.

Sound

The sound of the Bose QuietComfort Ultra Earbuds is of the caliber that we can recommend to demanding users, although yes, they are not better in this section than their predecessors. Moving on, in songs with intense sub-bass content, the Bose QuietComfort Ultra Earbuds deliver impressive low-frequency rumble. The bass depth remains powerful at low volumes and there is no noticeable distortion at higher volumes.

Likewise, these headphones put extra emphasis on the treble that keeps the vocals on the tracks clear and present. Meanwhile, tracks with shallower bass exhibit an almost thunderous sound, but never unnatural. The snaps and crackles of higher register percussion share the spotlight. However, the excessive emphasis on the treble may not convince some, but we are aware that many people like this type of sound, and if one thing is certain, it is that Bose has achieved a robust bass response with brilliant treble.

With that last thing in mind, if you’re not convinced by the default sound signature, you can try your luck with the sound equalizer in the official Bose Music app, which is effective at achieving changes in the bass, midrange, and treble.

Then we have spatial audio, which combines EQ, reverb and delay effects with psychoacoustics to create a more realistic dimensional sound experience. As a result, it creates the illusion in our head of listening to live music. Again, with the Bose Music application we can take advantage of additional functions, such as activating head tracking, although we must warn that the latter has not so convincing results and generates a certain delay.

How is the noise cancellation?

Experts agree that the Bose QuietComfort Ultra Earbuds offer some of the best noise cancellation experiences available in TWS headphones. Going into details, despite having a small dip in the mids, the Bose QuietComfort Ultra headphones dampen outside noise below 400Hz by up to 34dB , effectively reducing perceived volume by around 90%. As if that were not enough, they can silence noise above 1kHz by up to 39 dB, which is exceptional. Passive noise isolation is not far behind, and we can thank the shape of the ovoid mouthpiece and the tips that adapt quite well to the ears.

Likewise, we can change the intensity of the active noise cancellation from the App , and believe us, it is necessary if you want to be able to hear what is happening around you when you have them on. In this sense, there are 3 modes: Quiet, Aware and Immersive . It is also possible to combine ANC and Aware modes, as well as enable immersive audio mode and save these combinations in the app. It is important to note that you cannot deactivate ANC as such, only switch between the mentioned modes.

Microphones

Like most wireless earbuds, the Bose QuietComfort Ultra Earbuds have a microphone array for phone calls. Its performance is not bad at all, in fact, it is quite good, as it captures the user’s voice clearly and lets little of the ambient noise pass through to the other side of the call.

Autonomy

When it comes to battery, the Bose QuietComfort Ultra Earbuds can last us 6 hours, a fairly mediocre figure for their price, we must admit. That said, the charging case comes to the rescue and offers us up to 18 additional hours for a total of 24 hours, and that is clearly much better. Furthermore, it is our duty to warn that when using immersive audio, the autonomy suffers a considerable reduction, which leaves us with approximately 4 hours of use for each earphone.

Finally, the recharge time is 2 hours and unfortunately the case does not support wireless charging , so we will have to resort to the classic USB-C cable for this purpose.
