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

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.

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?

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.

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.

With ANC enabled, our testing shows that the Bose headphones block out an average of 85% of ambient noise, whereas the Sonos Ace only blocks out 74%.
