Sonos came out swinging with its first headphone offering. At a very premium price point, the Sonos Ace needs to have near-perfect performance to hold up against an established player like Bose. Does the new offering from Sonos have what it takes to beat the tried and true option from Bose? We put both headphones to the test to find out in this Sonos Ace vs Bose QuietComfort Ultra Headphones comparison.

What’s it like to use the Sonos Ace compared to the Bose QuietComfort Headphones?

The headphones share similar ear pads and headbands.

The Sonos Ace and Bose QuietComfort Ultra share a very similar design. In terms of style, I’d give the edge to the Sonos Ace, thanks to its metal accents on the headband and buttons. While the headband of the Bose QuietComfort Ultra Headphones may look metallic, it is an all-plastic design. At this price, that’s underwhelming.

On the other hand, the Bose QuietComfort Ultra Headphones have the edge in comfort. Thanks to its plastic construction, the Bose headphones are lighter at only 253g, compared to the Sonos Ace at 320g. The ear pads on the Bose headphones are also slightly softer. While I can still wear the Sonos Ace for multiple hours at a time, the Bose QuietComfort Ultra Headphones have all-day comfort.

Both headphones come with a nice carrying case along with cables for charging and wired listening. Neither have any water or sweat resistance, so you should think twice before buying the Sonos Ace or Bose QuietComfort Ultra Headphones for the gym.

You can control music playback on the Sonos Ace using a sliding button found on the right ear cup. There is a separate button for noise control.

Should you use the apps of either the Sonos Ace or Bose QuietComfort Ultra Headphones?

It’s important to download the companion app to get the most out of either set of headphones. For the Sonos Ace, that’s the Sonos app. For the Bose QuietComfort Ultra Headphones, it’s the Bose app. Both apps let you install the latest firmware updates, adjust noise canceling, and have basic equalizer functionality to adjust the bass and treble.

Each app also has some spatial audio features. Within the Bose app, you can activate Still Immersive Audio mode, which simulates the effect of your music coming from a speaker in front of you. Alternatively, there is a Motion Immersive Audio mode which keeps the music centered as you move your head around. Similarly, the Sonos app lets you toggle Dolby Atmos and head tracking modes.

If you have a compatible Sonos soundbar, you can set up TV Audio Swap within the Sonos app. This allows you to seamlessly transfer audio from your soundbar to your Sonos Ace headphones.

How do the Sonos Ace and Bose QuietComfort Ultra connect?

Both headphones support wired and wireless listening.

The Bose QuietComfort Ultra Headphones have Bluetooth 5.3 with support for LE audio. If you have a newer flagship Android phone, you may enjoy near-CD quality via aptX Lossless. Another way to get lossless listening is to simply use the included 2.5 to 3.5mm TRS cable.

Not to be outdone, the Sonos Ace have Bluetooth 5.4 and also bring support for aptX Lossless. You can listen wired with the Sonos Ace with the included USB-C to C and USB-C to 3.5mm cables.

I didn’t experience connection issues with either the Sonos Ace or Bose QuietComfort Ultra Headphones when paired to my iPhone. Both headphones have Bluetooth Multipoint support so you can seamlessly switch from your phone to laptop.

Is battery life better on the Sonos Ace or Bose QuietComfort Ultra Headphones?

In our standardized battery test, the Sonos Ace survived 32 hours and 13 minutes while the Bose QuietComfort Ultra Headphones only lasted for 27 hours and 37 minutes of continuous playback. While Sonos has the edge here, both last long enough to survive any plane trip or a week of normal use.

When it comes to fast charging, Sono also takes the crown. Three minutes of charging from empty gets you three hours of listening time with the Sonos Ace. On the other hand, 15 minutes of charging the Bose headphones only gets you two and half hours of listening time.

As you can see in the noise attenuation charts above, the Bose QuietComfort Ultra Headphones block out more low, mid, and high-frequency noise than the Sonos Ace. That said, the Sonos Ace still have good enough noise canceling for most people. I found that either headphone drowns out most of the noise around me on my commute to work.

Do the Sonos Ace sound better than the Bose QuietComfort Ultra Headphones?

Both the Sonos Ace and Bose QuietComfort Ultra Headphones have good sound quality. Whichever headphones you buy, you’ll probably be satisfied, though each have strengths and weaknesses. The Bose headphones have a default sound that more people will enjoy, but the Sonos Ace have much better spatial audio performance.

Both headphones have very basic equalizer functionality in their companion apps. You can broadly adjust the bass or treble, but you can’t fine-tune the frequency response to your liking with either. The Bose app has EQ presets, whereas the Sonos app does not.

Multi-Dimensional Audio Quality Scores (MDAQS)

The chart below shows how the sound of the Sonos Ace and Bose QuietComfort Ultra Headphones was assessed by the Multi-Dimensional Audio Quality Score (MDAQS) algorithm from HEAD acoustics.

A chart compares the MDAQS scores of the Sonos Ace and Bose QuietComfort Ultra Headphones.
The Bose QuietComfort Ultra Headphones have a slight edge thanks to their higher Timbre score.

On a scale from 1-5, the Bose QuietComfort Ultra Headphones get an Overall score of 4.6, whereas the Sonos Ace have an Overall score of 4.3. You’ll notice they each receive the same score in Distortion and Immersiveness. The difference in Overall score is due to the fact the algorithm puts the most weight on Timbre. In practice, the difference in scores here are non-significant.

Timbre (MOS-T) represents how faithfully the earbuds reproduce the frequency spectrum and temporal resolution (timing information).

Distortion (MOS-D) represents non-linearities and added noise: higher scores mean cleaner reproduction.

Immersiveness (MOS-I) represents perceived source width and positioning: how well virtual sound sources are defined in three-dimensional space.

See here for an explanation of MDAQS, how it works, and how it was developed.
