Products in the top-left offer the best value (high score, low price).

Professional reviewers praise the Beam (Gen 2) for its premium sound quality, clear dialogue, and effective Dolby Atmos implementation in a compact form factor, highlighting its strong smart-home features and seamless Sonos ecosystem compatibility, while noting drawbacks such as the absence of Bluetooth, limited Android support for Trueplay, and lack of DTS:X support.
Everyday users overwhelmingly appreciate the Beam's clear dialogue, easy HDMI ARC setup, reliable Wi-Fi and AirPlay 2 streaming, and its sleek design, though recurring complaints focus on missing Bluetooth, Android Trueplay limitations, occasional eARC negotiation issues, and modest bass without a subwoofer.

Professional reviewers commend the S40TR for its powerful, cinematic soundstage, robust Dolby and DTS decoding, and premium build, while noting the lack of Wi-Fi and voice-assistant features as a shortfall for a 2024-era sound system.
Everyday users praise the immersive surround experience, deep bass and dialogue clarity, but report Bluetooth lag, a dated ThinQ app and the need to power rear speakers with AC cords.
“Love the Sonos Beam... Great quality sound in a small package... I have them on both my big screen TVs.”

“Expensive but worth it”
