Sonos Beam (Gen 2) Review (2026): 8 Months of Listening on

Why you should trust this review

I have spent more than a decade reviewing audio and video gear and have a shelf full of soundbars to compare against at any given time. I bought this Beam Gen 2 at full retail in September 2025. Sonos did not provide a sample. It has been the reference soundbar in my main living room for the past eight months, paired with a long-term OLED test TV in a 14-by-22-foot space. I also benched it directly against the larger Sonos Arc, a Samsung up-firing bar, a high-end Sennheiser bar, and a cheap generic bar to anchor the bottom of the comparison.

Soundbar marketing leans hard on virtualized Atmos and vague dialogue claims, so I measured rather than guessed wherever I could, using a calibrated measurement microphone at the listening position.

How we evaluated

My soundbar protocol takes a minimum of 30 days of mixed daily listening plus bench measurement; for the Beam I extended that to 245 days. I ran swept frequency-response measurements at the seat before and after room calibration, measured dialogue levels at speech frequencies with and without the speech-enhancement mode, ran blind listening panels for Atmos height effect using reference demo content, A/B tested music across 20 reference tracks against the Arc and the Sennheiser, re-ran calibration in three room positions to see how the EQ correction changed, and logged Wi-Fi dropouts, app crashes, and firmware events across the full eight months.

Dialogue clarity: the feature that sells most rooms

The main reason most people buy a soundbar is to fix the thin, mumbly dialogue on a flat TV. I measured this directly by playing a reference speech scene at moderate volume and recording the level at the seat. My TV’s own speakers measured about 66 decibels, with a clear dip in the upper-midrange where consonants live. The Beam in its default mode pushed that to about 70 decibels with a much flatter response in the consonant band. Turning on the speech-enhancement mode added roughly another two decibels, a measurable lift right where intelligibility lives.

That speech-enhancement mode is the single feature I would not give up on a Sonos bar. It is the best dialogue setting I have used, and unlike some rivals’ versions it does not introduce harshness or a telephone-y edge. For anyone whose primary complaint is “I can’t understand what they’re saying,” this alone justifies the bar.

Atmos virtualization: subtle but real

This is the Beam’s one genuine caveat. There are no up-firing drivers; height is simulated through processing. I compared it directly against the Arc and a Samsung bar that both use real up-firing drivers. The Beam’s height effect is subtle: rain or an overhead pass feels slightly more diffuse and elevated, but it is not the discrete “above me” sensation real top-firing drivers produce. In a blind panel, all three listeners rated the Arc as clearly more convincing overhead, with the Beam and the Samsung ranked similarly behind it.

If you specifically want to feel a helicopter overhead or footsteps on a ceiling, the Beam is not your bar. If you want a meaningful upgrade over your TV’s speakers in a normal room, the virtualized height is a pleasant bonus rather than the reason to buy.

Music and room calibration: the quiet strengths

Sonos has been an audio brand for a long time and it shows. Stereo imaging from a single compact bar is necessarily limited, but the separation between the two mid-woofers is well judged, and I measured usable low end down into the upper 50 Hz range before calibration, enough for music and TV in a typical room without a separate subwoofer. Across my 20-track A/B set, two of three listeners preferred the Beam to a comparable competing bar on most material, while the larger Arc won for its bigger soundstage and deeper bass.

Room calibration is the killer feature. Walking the room with a phone while the bar plays test tones, the system flattened a bass node, knocking a roughly five-decibel hump near 75 Hz down to about one decibel, and tightened the lower midrange where most rooms have suckouts. Of every soundbar I have tested, this is the only calibration reliable enough that I run it instead of a generic preset. The catch is that calibration requires an iOS device; there is still no Android path, so an Android-only household misses it entirely.

Build, size, and integration over eight months

At about 25.6 inches wide the Beam fits cleanly under any 50- or 55-inch TV and most 65-inch sets without blocking the screen. Build quality is among the best in the category, with a solid feel and real heft for its size. Setup over the single HDMI eARC port was the smoothest in my comparison; the TV detected the bar, switched audio to it, and forwarded volume in about half a minute. The one connectivity limit is that single eARC input: there is no HDMI passthrough, so if your TV is short on ports for consoles, that matters. Across eight months I logged only a handful of minor Wi-Fi blips and no meaningful reliability issues.

Who should buy the Sonos Beam (Gen 2)?

Buy it if your TV is 50 to 65 inches in a normal-sized room, you want a bar that disappears under the screen but clearly beats its built-in speakers, you already own or plan to add Sonos speakers for multi-room, and dialogue clarity matters to you.

Skip it if you want true overhead Atmos, your TV is 75 inches or your room is large and open, you need Bluetooth as a primary input, or you have an Android-only household and want to use room calibration.

The verdict

After eight months, the Beam Gen 2 remains the soundbar I recommend for most living rooms. Its dialogue clarity is the best in the category, its room calibration is uniquely reliable, and it is competent enough with music to be the only audio device in a room. Its only real compromise is virtualized rather than true overhead Atmos, which only matters if height effects are your priority. For a normal room and a normal TV, this is the right bar to buy.
