Buying Guide: What to Look for in a WiFi Soundbar
Audio Performance and Immersion
The core of any soundbar is how it handles sound. Look for models that support Dolby Atmos and DTS:X for three-dimensional audio. Channel count matters: a 5.1.3 setup like the LG S80TR includes rear speakers and a center up-firing speaker for precise dialogue. The Sonos Era 300 uses six drivers and waveguides to bounce sound around the room, creating a spacious stereo field. If you prefer a slim design that still delivers, see our best slim soundbars guide.
Connectivity and Wireless Features
True WiFi soundbars connect directly to your home network, letting you stream music from Spotify, Apple Music, or your own library without Bluetooth compression. Both the LG and Sonos offer WiFi streaming, but the LG adds WOWCAST built-in for wireless Dolby Atmos transmission. The Sonos Era 300 also includes Bluetooth for quick pairing.

Room Calibration and Smart Controls
Every room affects sound differently. The LG S80TR uses an advanced room calibration that measures dimensions and optimizes audio settings automatically. The Sonos Era 300 relies on Trueplay (available on iOS) to adjust to your space. Both integrate with voice assistants: LG works with Google Assistant and Alexa, while Sonos offers its own Voice Control. For compact setups, see our best compact soundbars.
Final Thoughts
After evaluating both options, we recommend the LG S80TR 5.1.3 ch. OLED evo TV Matching Home for those who want a complete home theater experience with rear speakers and wireless subwoofer, while the Sonos Era 300 Wireless Smart Speaker with Dolby is ideal for music enthusiasts who value multi-room flexibility and expansive stereo sound. Both deliver excellent WiFi connectivity and will transform your listening experience.
