Sonos has released a new update to its iPhone app, introducing support for Apple’s first foldable smartphone, the iPhone Duo.

The update, Sonos 27.2, arrived on 15 October 2026 and ensures the Sonos app can operate in both the folded and unfolded configurations of Apple’s new device.

With the iPhone Duo launching on 23 October, Sonos is preparing its software ahead of time, allowing customers to control their home audio systems from Apple’s latest smartphone.

The update follows several months of improvements to the Sonos app, including redesigned navigation, new playback controls and additional music management features.

For listeners who already own Sonos speakers and are considering upgrading to the iPhone Duo, the latest update is good news.

Here’s everything you need to know about Sonos 27.2, what has changed and how to get the latest version.

What’s new in the Sonos 27.2 update?

The main addition in Sonos 27.2 is compatibility with Apple’s new iPhone Duo.

According to Sonos’ official release notes, the update introduces user interface support for the foldable device.

This means the app has been updated to accommodate the iPhone Duo’s two different screen configurations.

The iPhone Duo features a 5.4-inch external display, allowing it to function as a compact smartphone when closed.

Unfolding the device reveals a much larger 7.6-inch display, providing significantly more screen space for browsing applications and controlling connected devices.

Sonos has confirmed that its app supports both configurations.

This is particularly useful for people who use their phones to manage music throughout their homes, adjusting speaker volumes, changing playlists or controlling playback in different rooms.

The update is available through Apple’s App Store and can be installed manually.

How will Sonos work on the iPhone Duo?

The biggest difference between the iPhone Duo and a traditional iPhone is its folding display.

On a standard iPhone, the Sonos app operates within a relatively consistent screen layout.

With the iPhone Duo, applications need to adapt to two different screen sizes and potentially transition between them while running.

Sonos 27.2 introduces the necessary interface support for this new form factor.

Using Sonos with the iPhone Duo folded

When the iPhone Duo is closed, users can interact with the Sonos app through its smaller external display.

This provides a familiar smartphone experience for everyday tasks, such as selecting music or adjusting playback.

For many listeners, this will probably be the most convenient way to use Sonos while moving around the house.

There is little reason to unfold a larger screen simply to skip a track or adjust the volume.

Using Sonos with the iPhone Duo unfolded

Opening the iPhone Duo provides a considerably larger screen.

This extra space could be particularly useful when exploring music libraries, browsing albums or managing multiple Sonos speakers.

A larger interface also has the potential to make it easier to navigate music services and review what’s playing throughout the home.

However, Sonos has not published a detailed breakdown of how individual screens will be arranged on the unfolded iPhone Duo.

The confirmed change is interface compatibility, rather than a completely new tablet-style Sonos experience.

How to update the Sonos app on iPhone

The latest Sonos update is available now through the App Store.

To install it:

1. Open the App Store on your iPhone.
2. Search for the Sonos app.
3. Open the app’s listing.
4. Tap Update if a newer version is available.
5. Allow the update to download and install.

If the App Store only shows an Open button, the latest version may already be installed.

You can also refresh the list of available updates from your App Store account page.

The iPhone Duo compatibility update is listed as Sonos 27.2, with iOS app version 90.01.10.

It’s worth remembering that updating the Sonos app is different from updating the software installed on your Sonos speakers.

The new iPhone Duo support is an application interface update and does not require purchasing new speakers.

What other features has Sonos added recently?

Although Sonos 27.2 is a relatively small release, it follows several more substantial changes to the company’s mobile application.

Sonos has spent much of 2026 improving how users navigate music, manage speakers and control audio playback.

Some of the more useful recent additions include:

Redesigned app navigation

Sonos introduced an improved navigation experience with tabs designed to make it easier to move between music discovery, playback controls and search.

This reduces the need to move through multiple screens when looking for a particular song, album or artist.

For listeners who regularly switch between different music services, simpler navigation can make the Sonos app easier to use.

Improved volume controls

The company has also updated its volume interface and introduced additional gesture-based controls.

On supported iOS versions, users can adjust the volume of a room or group using a two-finger tap-and-rotate gesture.

These controls are particularly useful for households with several connected Sonos speakers.

Better music queue management

Sonos has introduced improvements to the playback queue, including the ability to add tracks using gestures and save queues as playlists.

Recent updates have also improved how queued content behaves when switching between radio and television audio.

For listeners who enjoy creating long playlists or regularly changing music throughout the day, these improvements provide more flexibility.

Lock Screen and Dynamic Island controls

Sonos has also brought back playback controls through iOS Live Activities, allowing users to interact with their audio system from the iPhone Lock Screen and Dynamic Island.

This can reduce the need to open the full Sonos app whenever a listener wants to control their music.

Together, these features demonstrate Sonos’ continuing efforts to make its application more convenient for everyday listening.

Does Sonos work with Apple Music on the iPhone Duo?

Yes. Sonos already supports Apple Music, and the new iPhone Duo update introduces compatibility with Apple’s foldable smartphone.

Listeners can use the Sonos app to access their connected music services and play music through compatible Sonos speakers.

Apple Music users can also take advantage of AirPlay with supported Sonos products.

This allows music to be streamed from an iPhone to compatible speakers without always needing to navigate through the Sonos app.

For listeners with multiple Sonos products, the system can also provide synchronised playback across rooms.

However, AirPlay support depends on the Sonos hardware being used, and not every older Sonos speaker supports the feature directly.

The iPhone Duo update does not change those existing hardware limitations.

Can you use Spotify with Sonos on the iPhone Duo?

Spotify is also supported by Sonos, making it possible to listen to playlists, albums and podcasts through compatible speakers.

Users can connect Spotify to their Sonos system through the Sonos app.

Spotify also offers direct playback controls for supported Sonos devices, allowing listeners to select their speakers from within Spotify itself.

That means iPhone Duo owners will have several ways to control their music.

They can browse through the Sonos app, use Spotify’s own playback interface or stream compatible audio through AirPlay.

The latest Sonos update focuses on making the Sonos application compatible with the new phone rather than introducing a separate music streaming integration.

Does Sonos 27.2 improve sound quality?

Sonos has not announced any specific sound-quality improvements as part of the 27.2 update.

The official release notes identify iPhone Duo interface compatibility as the main change.

There is no indication that the update introduces new audio formats, improved speaker performance or additional sound processing features.

For existing Sonos users with traditional iPhones, the update is therefore unlikely to make a noticeable difference to how their music sounds.

Its primary purpose is to ensure the application works with Apple’s new hardware.

When is the iPhone Duo coming out?

Apple’s first foldable iPhone will become available on Friday, 23 October 2026.

Pre-orders opened on 16 October, with prices starting at £1,999 in the UK.

The phone features two displays, allowing users to switch between a compact smartphone and a larger screen suited to multitasking and entertainment.

Its introduction creates new opportunities for app developers, particularly those building services that benefit from additional screen space.

Music streaming apps, media libraries and connected-home applications are among the categories that could benefit from adapting their interfaces to the foldable design.

Sonos is one of the early companies preparing its app for the device ahead of launch.

Will other music streaming apps support the iPhone Duo?

Apple’s move into foldable smartphones means developers will increasingly need to consider how their applications behave across different screen sizes.

Popular services such as Spotify, Apple Music and YouTube Music already offer mobile applications, but optimisation for the iPhone Duo’s unfolded display may vary.

A larger screen could potentially make music apps more useful by providing additional room for album artwork, browsing controls, lyrics and playlists.

For example, a music streaming service could use the expanded display to provide more information about an artist while keeping playback controls visible.

These are possibilities rather than confirmed features across the major streaming apps.

As the iPhone Duo reaches customers, it will become clearer how individual developers are taking advantage of the new hardware.

Why does iPhone Duo support matter for Sonos users?

For people who already own Sonos speakers, the biggest benefit is compatibility.

Buying a new smartphone shouldn’t mean losing access to the applications used to control music and connected devices around the home.

By releasing its update before the iPhone Duo becomes available, Sonos is helping ensure customers can continue using their audio systems when they switch phones.

The foldable design could also make the Sonos app more convenient for people with complex speaker setups.

A larger display may prove useful when navigating music libraries or managing audio across several rooms.

However, the real benefit will depend on how successfully Sonos has adapted its interface to the new hardware.

For now, the update is a practical improvement rather than a major overhaul.

Is the Sonos 27.2 update worth installing?

For anyone planning to buy the iPhone Duo, updating to Sonos 27.2 is a sensible step.

It adds the interface support required for Apple’s new foldable phone and is available ahead of the device’s release.

Existing iPhone users can also install the update, although they should not expect major new functionality specifically from version 27.2.

The more significant Sonos improvements arrived through earlier updates, which introduced redesigned navigation, better music management and additional playback controls.

As foldable smartphones become more common, support for different display configurations is likely to become increasingly important for music and entertainment apps.

Sonos’ latest update is a small but useful example of that transition.

For listeners, the result is simple: whether the iPhone Duo is folded or unfolded, Sonos is preparing to make controlling music at home a familiar experience.
