    4. USB-C port
      • The USB-C port is designed for line-in and Ethernet connections using the Sonos Line-In Adapter or Combo Adapter (sold separately). It’s not a power source for the speaker and shouldn’t be used to charge other devices.
      • Ethernet: Use the Sonos Combo Adapter and an Ethernet cable to connect Era 300 directly to your router if you want to hardwire your speaker (helpful if your WiFi is unstable).
      • Line-in Use either the Sonos Line-In Adapter or Combo Adapter to connect your turntable, CD player, projector, or other device.

    Select a Location

    Trueplay tuning will balance the sound for wherever you place Era 300, but for the speaker to project sound most effectively, here are a few guidelines.

    • Era 300 should be placed indoors and have approximately two feet (.61 m) of overhead clearance for optimal sound quality. Placement in an enclosed space like a bookshelf is not recommended, as this could impact dispersion and playback clarity.
    • If you are mounting Era 300 within 2 ft (.61 m) of a ceiling, place it upside down for the best sound.
    • When Era 300 is placed next to a wall or on a shelf, leave at least 1″ (2.5 cm) clearance in back and 8” (20.32 cm) on each side of the speaker.
    • When using Era 300 speakers as surrounds, leave at least 8″ (20.32 cm) clearance around the sides of each speaker.
    • Traditional stereo setups often have an ideal place to sit in a room for the best listening experience, but with Era 300, the sound is sent in all directions, so you’ll experience rich detail no matter where you’re seated.
    • Don’t position Era 300 vertically or at a steep angle, or the audio will stop.

    Bluetooth Pairing

    1. Turn Bluetooth on in your device settings.
    2. Press and hold the Bluetooth button on the back of the speaker until you hear a tone, then release.
    3. The status light blinks blue when the speaker is ready to pair.
    4. Choose Sonos Era 300 from the list of available devices in your Bluetooth settings.
    5. Your mobile device will automatically connect next time.

    Microphone on/off

    There are two ways to control the microphones on the Era 300

    A universal microphone switch on the back turns all microphones on and off. A voice services button on top turns voice services on and off without affecting the microphones needed for Trueplay and other microphone-enabled features.

    • When both are on, voice control and all microphone-enabled features are available.
    • When both are off, voice control and all microphone-enabled features are unavailable.
    • When the universal microphone switch is on, and the voice services light is off,
    • Trueplay and other microphone-enabled features are available, but voice control is off.

    Trueplay

    • Trueplay tuning measures how sound reflects off walls, furnishings, and other surfaces in a room, then fine-tunes your Sonos speaker to make sure it sounds great no matter where you place it.
    • During setup, choose the Trueplay option that works best for you and your space.
    • To retune later, go to Settings > System, choose a room, and select Trueplay.
    • If VoiceOver is enabled on your iOS device, Trueplay tuning isn’t available.
    • Turn it off in your device settings before tuning your speakers.
    Advanced Tuning

    Advanced tuning is custom and precise. It takes about 5 minutes and uses the microphone on an iOS device (running iOS 8 or later), so you’ll move around the room while the sound is fine-tuned for your space. Advanced tuning is the best choice for large rooms (open concept spaces may experience less precise tuning).

    Quick Tuning

    Quick tuning is fast, effortless, and accessible. It takes about a minute and uses the microphone on your Sonos product to detect the environment, so there’s no need to move around the room during tuning. Quick Tuning is available for both iOS and Android, and is a good choice for smaller rooms or spaces where it’s difficult to move easily.

    Auto Trueplay

    Portable Sonos products like Sonos Roam and Move can tune themselves automatically. Auto Trueplay uses your speaker’s microphone to detect the environment and make periodic tuning adjustments so you get great sound wherever your speaker is and whatever you’re listening to. Go to > System, and select your portable speaker to turn on auto Trueplay.

    Set Up Tereo Pair

    • Pair two Sonos speakers in the same room for an even wider, stereo experience.
    • One speaker serves as the left channel, and one serves as the right channel.
    • The Sonos speakers in a stereo pair must be the same type.
    • Place the speakers 8 to 10 feet apart. Your favorite listening position should be 8 to 12 feet from the paired speakers—less distance increases bass, more distance improves stereo imaging.
    • Go to > System. Select one of the speakers you want to use in the stereo pair, then choose Set Up Stereo Pair to get started.

    Set Up the Surrounds

    It’s easy to turn two Sonos speakers (same model), or a Sonos Amp and your favorite non-Sonos speakers, into separate right and left channels for your home theater.

    1. Place each surround speaker about 10 ft from your favorite listening position, angling
      them toward the seating area.
    2. Go to > System. Select a room with a soundbar and choose Add Surrounds to get started.
    3. If you group the rooms or create a stereo pair instead, you won’t have surround sound.

    Surround Audio Settings

    During setup, surround sound is optimized for your room. These settings are adjustable.

    SurroundsTurn surround sound on or off.
    TV LevelAdjust the surround volume for TV audio.
    Music LevelAdjust the surround volume for music.

    Voice services

    Use your voice to control your Sonos system with any voice-enabled Sonos product—play and control content, turn the volume up or down, and more.

    Sonos Voice Control

      • Control your whole Sonos system with hands-free ease and unmatched privacy. Sonos Voice Control comes ready to use—it only takes a few seconds to add when you set up your speakers.

    Amazon Alexa

      • You’ll need the Sonos app and the Alexa app with the Sonos skill enabled. You’ll make some changes in both apps during setup.

    Siri

      • You’ll need the Apple Home app. Add your AirPlay2-compatible Sonos speakers to the Apple Home app and then use an iPhone, iPad, or Apple TV to ask Siri to play music (currently limited to Apple Music).

    Line-in

    Connect an audio device, like a projector, CD player, or turntable (with a built-in phono preamp), to any Sonos product that has a line-in port (Era 300, Era 100, Amp, Port, or Five). Then go to > Line-In to select the source and start playback. Era 300 and Era 100 require a Sonos Line-In or Combo Adapter (sold separately). Other products may require a different type of line-in adapter depending on your audio source.

    Product Settings

    You can customize Sonos products for your surroundings. Go to > System and select a product.

    Room NameIf you move your speaker to a new room, you can change its name in Settings.
    Turn off WiFi (not available for Era 100, Era 300, or portable products)You can turn off your speaker’s WiFi when it’s connected to your network with an Ethernet cable.
    EQSonos products ship with preset equalization settings.
    TrueplayTrueplay adapts the sound for your surroundings and content.
    Volume LimitYou can set a maximum volume for each room.
    Status LightDisplays the speaker’s connection to WiFi, indicates when the volume is muted, and signals errors.
    Touch ControlsYou can disable the touch control on your speaker.
    Battery Saver (for portable products only)To save battery life, you can set your portable speaker to power off automatically instead of going to sleep.

    Line-In

    (for Sonos products with line-in capability)

    When a projector, turntable, stereo, or other audio device is connected to a Sonos product, you can adjust these line-in settings.

    • Source name
      • Choose a name for the line-in device.
    • Source level
      • Adjust the line-in source level if you find the default volume setting is too quiet or distorted.
    • Audio Delay
      • Add a delay between the line-in source and Sonos to reduce the chance of audio issues occurring when you’re playing line-in audio on grouped speakers.
    • Autoplay
      • Choose a room if you want line-in audio to start playing automatically when Sonos detects a signal on the line-in port. (Autoplay is disabled by default.)

    FAQs

    Q: What makes the Sonos Era 300 different from other Sonos speakers?

    Compared to conventional smart speakers, this enables the speaker to support Dolby Atmos music and produce a more immersive soundstage.

    Q: Do I need the Sonos app to set up the Era 300?

    Q: How do I enable Alexa on the Era 300?

    You can designate Alexa as your voice assistant during setup. To link your Amazon account, open the Sonos app, select Settings → Services & Voice → Add a Voice Assistant, and then follow the instructions.

    AirPlay 2, Wi-Fi 6, Bluetooth audio, and optional Ethernet with the Sonos Combo Adapter are all supported.

    Q: Does the speaker require a separate subwoofer or amplifier?

    The Era 300 is an autonomous smart speaker. Pairing it with a Sonos Sub or Sub Mini is an optional feature that primarily improves low-frequency performance.

    Q: Can the Era 300 be used as a home theater surround speaker?

    Yes. When paired with a compatible Sonos soundbar (Arc or Beam Gen 2), the Era 300 can serve as spatial audio surrounds, creating a Dolby Atmos-capable surround system.

    Q: What is Trueplay, and should I use it?

    Sonos’ Trueplay tuning technology adapts the speaker’s sound to the acoustics of your space.
