Sonos Era 300 Wireless Smart Speaker — Black, Dolby Atmos, Wi‑Fi & Bluetooth Streaming

The Sonos Era 300 is a compact wireless smart speaker engineered to deliver immersive, room-filling Dolby Atmos sound that surrounds you from wall to wall and floor to ceiling.

Designed for listeners who want more than stereo, the Era 300 blends six precisely placed drivers, custom waveguides, and modern streaming flexibility to create a multidimensional audio experience. It connects over WiFi for lossless streaming, supports Bluetooth for quick pairing, and accepts a 3.5 mm line-in for turntables or other sources. When paired with a Sonos Arc or Beam (Gen 2), two Era 300 speakers extend Dolby Atmos playback to provide true multichannel surround sound.

How does the Era 300 create a three-dimensional listening experience?

Its breakthrough acoustic layout puts drivers around the front, sides, and top so sound can project horizontally and vertically. Custom waveguides steer audio right, left, forward, and upward to generate a broad, enveloping soundstage that makes instruments and effects feel positioned around you.

• Six optimally positioned drivers for directional sound
• Waveguides that disperse audio across the room
• Designed to support Dolby Atmos Music and spatial mixes

What connectivity and streaming options are available?

The Era 300 supports WiFi for integrated streaming from services and multiroom grouping, plus Bluetooth for device-to-speaker playback without WiFi. A 3.5 mm line-in (via Sonos Line-In Adapter) lets you connect analog sources like turntables, and the speaker receives feature updates and new services through Sonos software.

• Stream over WiFi from major music services and Sonos Radio
• Bluetooth pairing with a single button press for quick playback
• Auxiliary 3.5 mm input using Sonos Line-In Adapter for external devices

Can Era 300 be part of a surround or multiroom setup?

Yes—pair two Era 300 units with a Sonos Arc or Beam (Gen 2) to create enhanced multichannel surround sound powered by Dolby Atmos. You can also add Era 300 speakers into a multiroom Sonos system for synchronized playback across different spaces.

• Use two Era 300s as rear surrounds with Arc or Beam (Gen 2)
• Group with other Sonos speakers for whole-home audio
• Automatic software improvements via Sonos updates

How does it fit into daily life and controls?

Controls are designed for convenience: touch controls on the speaker, app-based setup and management, and Sonos Voice Control for hands-free listening with privacy-conscious design. The speaker’s compact footprint and black finish make it suitable for desktops, shelves, or placed on a media console.

• Touch controls for play, pause, and volume
• Sonos app for configuration, EQ, and grouping
• Optional voice control with privacy-first features

Who is this for: The Sonos Era 300 is ideal for music lovers and home theater enthusiasts who want spatial, Dolby Atmos-capable sound from a single compact speaker. It suits people who value flexible connectivity—WiFi, Bluetooth, and line-in—plus those planning to build a Sonos surround or multiroom system over time. If you want a modern, upgradeable speaker that emphasizes immersive audio detail and room-filling presence without occupying much space, the Era 300 is a strong fit.
