Sonos dips its toes into hi-res audio streaming with Qobuz

For years, Sonos steadfastly refused to support hi-res music formats on its massively popular line of wireless speakers. Today, that finally changes: All Sonos users who are currently running the S2 version of the company’s software will be able to stream hi-res music from Qobuz, with a valid subscription. Qobuz debuted its streaming music service in the U.S. in 2019.

With a Qobuz subscription, which starts at $15 per month, those who own one or more compatible Sonos products will be able to play hi-res streams at 48kHz/24-bit quality, marking the first time that Sonos speakers have been able to play better-than-CD-quality music. At the moment, the S2 software will support 48kHz/24-bit streams from Qobuz or 48kHz/24-bit music files from people’s personal audio collection.

Compatible products include the Arc, Beam, Five, Move, One, One SL, Port, Amp, Symfonisk Bookshelf, Symfonisk Table Lamp, Playbar, Playbase, and Play:5 (Gen 2). The forthcoming Sonos Roam will also be hi-res compatible. Notably absent from the list is the Sonos Play:1, and yet this older speaker is still compatible with the S2 software. Sonos tells us that in situations where people try to stream hi-res audio to a non-hi-res Sonos speaker (whether on its own or grouped with hi-res capable devices), the non-hi-res speaker will get a 16-bit version of the song, while the compatible products will get the 24-bit version.

Hi-res music is regarded by many as superior to both CD audio as well as virtually all lossy digital formats like MP3 and AAC because it captures and retains more information about the original song. To hear hi-res music, you need a source — like a streaming music service or your own collection of hi-res tracks — and a device that is capable of decoding and playing these tracks. Given that CD audio is captured at a sample rate of 44.1kHz and a sample size of 16-bits, anything that captures and preserves more data than this is usually considered hi-res.

However, it’s worth noting that the Japan Audio Society, which maintains the definition of what qualifies as hi-res audio, claims that any 24-bit file with a sample rate of less than 96kHz does not qualify.

When Digital Trends asked Sonos why hi-res support is currently limited to 48/24, a spokesperson told us that higher-quality tracks are “not widely supported by streaming services. We’re continuing to watch how high-resolution audio evolves and will explore changes to our platform over time.” We’re not entirely sure we agree with this statement. While it’s true that Apple Music and Spotify (and even the upcoming Spotify HiFi) do not support hi-res audio at all, Tidal, Qobuz, and Amazon Music HD all offer hi-res tracks at 96kHz/24-bit (or better) quality.

Now that Sonos has (more or less) joined the hi-res music party, the question is whether and when it will expand this support to higher quality versions of hi-res, other streaming services beyond Qobuz.

We’ll let you know as soon as Sonos has more to say on these issues.

What is Tidal? The hi-fi streaming music service fully explained
Two Tidal UI screens on smartphones.

Most big-name music streaming services have a lot in common. Apple Music, Spotify, Amazon Music, Pandora, and YouTube Music all have similar choices in music and quality -- it's just a matter of picking your preferred platform.

Tidal, on the other hand, breaks the mold. The business structure emphasizes the artists having more control over the platform, and it offers higher-quality audio in comparison to the big names. We have all the details on how this service works so you can decide if it's right for you.

Tidal begins its rollout of hi-res lossless audio
best buy offers free tidal with select products

Tidal has said that starting today, select subscribers will be able to access its catalog of music in hi-res lossless audio that uses the open-source FLAC format. The announcement was made via a Reddit post in which CEO Jesse Dorogusker said that hi-res FLAC tracks, in up to 24-bit/192kHz resolution, are now available to the company's Early Access Program (EAP) users on iOS. Dorogusker says the company wants feedback from this smaller group of listeners before rolling out the format more broadly. All HiFi Plus subscribers are expected to get access to the new format by August.

If you're an EAP member, you can access the new hi-res lossless content by updating your beta app and selecting "Max" quality in the new Audio & Playback settings screen.

Sennheiser updates its Momentum headphones with personal tuning, hi-res audio
Sennheiser Momentum Wireless 4

Sennheiser has released an update to its Smart Control software -- the companion app that Sennheiser customers use to adjust the settings and upgrade the firmware on the company's wireless headphones and earbuds. The update contains a number of new features for the Momentum 4 Wireless headphones and the Momentum True Wireless 3 earbuds, including sound personalization, deeper EQ settings, a fit test, and hi-res audio at up to 24-bit/96kHz.

Both the Momentum 4 Wireless and Momentum True Wireless 3 benefit from the new Sound Personalization tuning feature, which has been designed in conjunction with the Fraunhofer Institute for Digital Media Technology (IDMT). Not sure why that matters? It's the entity that invented the MP3 file format and it has also done tons of research in the intervening years on how people hear audio.
