Sonos Beam Gen 1 vs TCL S65K S
Quick Verdict
Choose the Sonos Beam Gen 1 if you want a compact voice-controlled soundbar with clear dialogue, built in Alexa, and Sonos ecosystem integration. Choose the TCL S65K S if you want a complete 5.1 system with Dolby Atmos, DTS:X, a wireless subwoofer, and wireless surround speakers. The TCL gives more published audio hardware and immersive formats, while the Sonos leads in voice assistant and app support. Both have missing specs, but the TCL advertises a fuller home theater package. Buy Sonos for simplicity and voice, buy TCL for surround and bass.

Sound Quality
Both models score 24 out of 30 for sound quality, so they are tied on paper. The Sonos Beam Gen 1 lists a dedicated tweeter for dialogue clarity, but its channel count, total driver count, and power output are not published. The TCL S65K S publishes a 5.1 channel configuration and a built in center channel tweeter for clear speech, yet it also omits total driver count and power. The difference is that TCL provides more structural detail about its driver arrangement.
The Sonos Beam Gen 1 relies on that single tweeter to improve speech intelligibility, which is useful for TV and movie dialogue. However, without details on other drivers, we cannot assess its full range, stereo separation, or maximum loudness. The TCL S65K S includes a center channel and additional channels, suggesting a broader front soundstage, but the missing total driver count and power limit a complete judgment. The identical sound quality score suggests parity, yet the underlying specifications differ significantly.
Buyers who value a clearly advertised dialogue focused tweeter and a known Sonos tuning approach may prefer the Beam Gen 1. Buyers who want a listed 5.1 array with a dedicated center channel may lean toward the TCL. Since power output is absent for both, neither model can be assessed for maximum output or headroom. The listing facts alone place these bars at a similar level for core sound, but with different design philosophies.
Surround, Atmos and Audio Formats
This is where the TCL S65K S separates itself on paper. The listing states Dolby Atmos and DTS:X decoding, alongside a 5.1 setup with wireless surround speakers. The Sonos Beam Gen 1 does not publish any Dolby Atmos or DTS support in its listing, and its surround and audio formats score is 8 out of 15 compared to TCL's 12. That difference reflects TCL's documented immersive audio formats.
The TCL's inclusion of wireless surround speakers means the system can produce actual rear channel effects out of the box. The Sonos Beam Gen 1 listing does not mention surround speakers or virtual surround processing. Therefore, buyers who want discrete surround sound from a single purchase have a clearer path with the TCL. The Sonos listing does not state any surround expansion options, so we cannot compare them.
For object based audio, Dolby Atmos and DTS:X are important for height effects and precise placement. TCL lists these formats, while Sonos does not. That does not mean the Sonos cannot play Atmos content, but the listing provides no evidence. On the basis of published specifications, the TCL S65K S is the stronger choice for surround and immersive formats.
Subwoofer and Bass
The TCL S65K S comes with a wireless subwoofer that includes a 6.5 inch driver and a Bass Boost feature. This published component gives the TCL a clear advantage for low frequency output. The Sonos Beam Gen 1 listing does not publish any subwoofer information, so its bass performance cannot be assessed from the supplied facts.
Without a subwoofer spec, the Sonos Beam Gen 1 likely relies on internal drivers for bass, but the listing gives no driver size or power. The TCL's dedicated subwoofer should handle deep bass more effectively, especially with Bass Boost engaged. Buyers who prioritize movie rumble or music impact will find the TCL's subwoofer a tangible benefit.
On the other hand, the Sonos Beam Gen 1 may be designed for smaller rooms where a subwoofer is not needed, but again the listing does not state that. In this comparison, the TCL S65K S has an unambiguous subwoofer claim, while the Sonos offers none. That makes the TCL the safer choice for documented bass performance.
Connectivity and TV Setup
The Sonos Beam Gen 1 lists a two cord setup with automatic remote detection, which suggests simple HDMI and power connections, but the listing does not publish HDMI version, eARC support, or other input details. The TCL S65K S also uses a single HDMI cable and does not explicitly state eARC support. Both models appear to rely on HDMI for TV connection, but the lack of eARC confirmation for both is a notable gap.
For wireless connectivity, the TCL S65K S lists Bluetooth wireless music streaming. The Sonos Beam Gen 1 lists built in Alexa and Sonos app control, but its wireless protocols are not published. Bluetooth is a simple, widely compatible option for music from phones. Sonos app control may enable multiroom streaming through the Sonos ecosystem, but the listing does not confirm WiFi or other wireless standards.
Neither model publishes HDMI eARC support, which affects passthrough of lossless Atmos from a TV. If a TV only has ARC, Dolby Atmos may still work via compressed codecs, but the listings do not confirm this. Buyers who need verified eARC for high bandwidth audio should check both models further. On the connectivity score, Sonos leads 12 to 10, but the actual connection details remain incomplete for both.
Features, Apps and Voice Control
The Sonos Beam Gen 1 has built in Alexa voice assistant and Sonos app control, plus a remote control mentioned in the listing. This gives it a clear advantage in voice control and app integration. The TCL S65K S does not publish any app or voice assistant details, so its smart features are largely unknown. The TCL does include AI Sonic Auto Room Calibration, which is a useful feature for tuning the sound to the room.
Sonos also mentions multiroom ecosystem compatibility in its pros, which means it can integrate with other Sonos speakers. The TCL has no such multiroom claim. However, the TCL's auto room calibration may improve audio performance in varied rooms without manual adjustment. The Sonos listing does not mention any room calibration feature, so we cannot compare that aspect.
On the features score, Sonos leads 13 to 11, reflecting its stronger published software ecosystem. If voice control and multiroom audio are priorities, the Sonos Beam Gen 1 is the more documented choice. If automatic room tuning and a simple out of box experience matter more, the TCL offers that specific feature. Neither model publishes a complete app or remote spec, so buyers should verify before purchase.
Design and Fit Under a TV
Both soundbars have a design score difference of 12 for Sonos and 10 for TCL. The Sonos Beam Gen 1 is described as a compact black design for smaller TV spaces. The TCL S65K S is a 5.1 system that includes a main soundbar, wireless subwoofer, and wireless surround speakers, so it requires more physical space and setup.
The Sonos Beam Gen 1 dimensions are not published, so we cannot confirm its exact height, width, or depth. The TCL S65K S also omits dimensions and weight in the listing. Without measurements, buyers cannot be certain either model will fit under a specific TV or on a media stand. However, based on the component count alone, the Sonos is likely to have a smaller footprint.
The TCL's separate subwoofer and surround speakers need placement and power outlets, which may be a drawback for minimalist setups. The Sonos Beam Gen 1 is a single bar, so it fits more easily in tight spaces. The published description of the Sonos as compact supports that view, while the TCL's complete system description implies a larger overall footprint. Buyers with limited space should consider the Sonos, while those with room for satellites may prefer the TCL for fuller immersion.
Who Should Buy It
The Sonos Beam Gen 1 is best for buyers who want a compact soundbar focused on clear TV dialogue, music streaming, and voice control without needing published surround or bass specs. The listing highlights its dedicated tweeter for speech, built in Alexa, Sonos app control, and two cord setup. Existing Sonos users will appreciate the multiroom ecosystem compatibility mentioned.
The TCL S65K S is best for listeners who want a lower midrange 5.1 Atmos soundbar with wireless surrounds and subwoofer without a complex setup. The listing provides Dolby Atmos and DTS:X decoding, a wireless 6.5 inch subwoofer, wireless surround speakers, and a built in center channel. Buyers who want a complete home theater package from a single purchase should consider it.
The Sonos is a better fit for small rooms or secondary TVs where dialogue clarity and voice control matter more than booming bass or surround effects. The TCL suits larger rooms or buyers who want a true multi channel experience without running cables. Each product has clear strengths, but the missing specifications on the Sonos for surround and bass make it a less complete home theater solution on paper.
The Deciding Question
The central question is whether you need a complete 5.1 Dolby Atmos system with a wireless subwoofer and surround speakers today, or whether you prefer a compact voice controlled soundbar that integrates with Sonos. The TCL S65K S answers the first need with published features. The Sonos Beam Gen 1 answers the second with built in Alexa and Sonos app control, but lacks published surround and bass specs.
Another key question is how much you value documented specifications. The TCL publishes channels, Atmos, DTS:X, subwoofer driver, and Bluetooth, but omits power, total driver count, eARC, and app details. The Sonos omits even more, including channels, power, subwoofer, Atmos, and dimensions. If you are comfortable with unknown specs, either may work; if not, the TCL gives more verified audio features.
Finally, consider the room size and setup complexity. A single compact bar is easier to place under a TV, but it may not deliver the same immersion as a 5.1 system. The Sonos Beam Gen 1 is likely smaller and simpler, while the TCL S65K S requires space for a subwoofer and two surround speakers. Answering these practical questions will guide the choice.
Who Should Buy Which
Buy the Sonos Beam Gen 1 if you already own Sonos speakers, rely on Alexa for voice control, or need a space saving bar that prioritizes clear dialogue. Its published strengths are the dedicated tweeter, built in Alexa, Sonos app, multiroom ecosystem, and two cord setup. It remains a solid choice for music streaming within the Sonos platform, but you must accept missing specs for surround, bass, power, and Atmos.
Buy the TCL S65K S if you want a documented 5.1 channel system with Dolby Atmos and DTS:X, a wireless subwoofer with a 6.5 inch driver, wireless surround speakers, and Bluetooth music streaming. Its AI Sonic auto room calibration is a useful extra. The TCL is the stronger home theater package on paper, especially for movies and games that use discrete surround channels.
If your budget is fixed and you want the most immersive sound from a single product listing, the TCL S65K S is the clear value. If you prioritize voice control, app ecosystem, and a compact form factor over surround and bass, the Sonos Beam Gen 1 is the better fit. Both have moderate overall scores, but the TCL gives you more published audio hardware for the money.
