The battery-powered speaker includes both 802.11n Wi-Fi and Bluetooth wireless technology, so users can use it as part of their Sonos multi-room system at home and then switch to Bluetooth streaming when out and about.
While the capacitive touch controls remain - matching the newer speakers in the Sonos line up like the Beam, Playbase and portable Move - the Sonos One SL doesn't have the microphone button, nor the holes around the controls.
It also has a line-in, so you can add playback devices like that aforementioned turntable or CD player to a Sonos speaker setup - the Port can wirelessly beam music from that line-in to any other Sonos devices on your network. A "Suspend" mode, which is activated automatically when not in use or by tapping the power button, is created to reserve the battery for up to five days. This is the company's first device to support Bluetooth streaming, so you will finally be able to play music on it without needing a WiFi connection. Rather than continuing to sell the six-year-old Play:1, replacing it with the One SL means all fo Sonos' speakers support AirPlay 2.
Unlike the Sonos One, which lets you request songs, albums, playlists, and podcasts using the Google Assistant or Alexa voice assistants - as well as all the usual AI assistant tricks too - like asking for the latest weather and news updates, ordering a take-away or an Uber, Sonos One SL can't understand any of that.
While the Move may share much of the Sonos One's design DNA, it's has been built to survive its out-of-home adventures with a more durable exterior and IP56 rating.
The Move ships later this month and is available for pre-order now on sonos.com.
Instead, the Sonos One SL is focused on delivering the same room-filling sound we're accustomed to from the Sonos One and, before it, the Play 1.
The Move features two Class-D amplifiers that power a down-firing tweeter for the highs, while a mid-woofer handles the mids and bass.
Sonos One SL is available worldwide from September 12, 2019 and costs £179.
While not competing with Amazon for the sheer quantity of products launched during IFA, Sonos hasn't limited today's announcements to just one new product.
The Sonos Port is the successor to the Sonos Connect box, which some Sonos fans felt is no longer quite in keeping with the rest of the Sonos range's reserved aesthetic.
