Sonos launches Ace Ultra headphones, Beam Ultra soundbar and Sonos 27 OS, adding speaker-positioning tech

Somebody carries a Play speaker from the kitchen to the side table behind the couch, sits down, and the movie has rear channels. No app, no setup wizard. That is the quietest thing Sonos announced and the only one that visibly worked in front of press: Sonos Positioning Technology uses high-frequency sounds to sense where each speaker is standing and then changes that speaker's role in the system, which is how a Move 2 or a Play ends up as a rear surround ^[7]. Engadget's reporter had a pair of Play speakers set down behind the seating and join as surrounds on their own, and reported that panning audio became much more noticeable and announcer voices picked up reverb ^[14].

Multi-room audio has always assumed people name their rooms carefully and revisit the configuration whenever the furniture moves. In practice, most people just carry the portable speaker to wherever they happen to be sitting and never open the settings screen again. Positioning is built for that second habit, which makes it the first Sonos software decision in a while that starts from observed behaviour rather than from a redesign.

The marketing weight, though, sits on the headphones. Sonos calls Ace Ultra its first headphone that connects directly into the Sonos system ^[11], and Notebookcheck reports the company presenting the one-button audio handoff as a fix for the original Ace, which never fully joined the wider system ^[12]. Engadget, standing in the demo room, points out that the original Ace could already pull audio off a soundbar once the long-delayed updates arrived, and declines to call the Ace Ultra version a major new feature ^[13]. Thurrott dates the caution behind all of this to two years of playing it safe after Sonosgate ^[18].

Then the money. $699 and $449 come to $1,148 ^[2][20], and that total buys neither the surrounds that carried the best demo nor a subwoofer; the Sinners scene that Engadget rated the most impressive of the day had Play speakers behind the couch ^[16]. In fairness, the Beam Ultra on its own drew a note about impressive bass with nothing else connected ^[15], and it is nearly four inches longer than the second-generation Beam, which is a cabinet measurement worth taking before ordering ^[9].

Sort each announced feature on two axes: whether it removes a step the household currently performs in the app, and whether it needs hardware nobody in the house owns yet. Positioning removes a step and runs on speakers already on the shelf, which is why it is the feature to test first. The new app navigation also removes steps and costs nothing ^[4]. The Ace Ultra button press takes the phone out of the loop for $449. Sonos 27voice and 27mcp add an interface rather than removing one, and they did demo well: Engadget got MTV Unplugged in New York out of "play that acoustic live Nirvana album" and switched All Along the Watchtower from Hendrix to Dylan on request ^[17][6].

For existing owners the recommendation is dull. September 8 is the date that actually matters, well ahead of the September 29 launch. You get 21 days ^[21] to learn whether the rewritten navigation survives contact with your own household before spending anything, and the cost of waiting is a preorder slot. Sonos says full details of the software features are coming soon ^[4], and Conrad's framing is that this is just the start of what the audio operating system can do ^[22]. The measure to hold it to is narrower than that: whether anyone in the house still has to open the app to get sound where they want it.
