Samsung S700D 3.1ch Soundbar w Wireless Dolby Atmos - Slim 3.1ch

Our review of the Samsung S700D 3.1ch soundbar finds a compact, well-rounded option for people who want better TV audio without a tangle of cables or a bulky speaker array. The single biggest reason to buy is its combination of a truly ultra-slim profile and wireless Dolby Atmos capability, which brings noticeably improved spatial imaging for movies and shows while fitting discreetly beneath a 50' or smaller TV. Setup is straightforward and the bar pairs smoothly with Samsung TVs using Q-Symphony, making it an easy upgrade for bedroom, small living room, or secondary TV use.

Key Features

• Ultra-slim design: The low-profile chassis delivers stronger audio without dominating the room, making it easy to blend under a TV stand or on a media shelf.
• 3.1ch Dolby Atmos: The soundbar and sub configuration provides a wider soundstage and clearer height cues compared with standard stereo bars, improving immersion for movies and sports.
• Wireless Dolby Atmos: Wireless surround capability reduces cable clutter while preserving the Dolby Atmos experience for supported content.
• Q-Symphony compatibility: When paired with a compatible Samsung TV the soundbar works together with TV speakers to optimize channels and improve overall clarity.
• Smart integration: Built-in support for voice assistants and streaming like Alexa, Chromecast and AirPlay makes casting and control convenient without added devices.
• Easy pairing: The included rear speaker kit pairs simply and quickly, allowing consumers to extend surround sound without a complex setup.

Who It's For

The S700D suits owners of Samsung 50' TVs and smaller rooms who want clear dialogue and a compact footprint rather than a full A/V receiver and tower speakers. It is a good fit for renters or anyone prioritizing a neat, cable-light setup with modern streaming and voice features.

Those who want heavy bass for large open rooms, or audiophiles after reference-level fidelity, should look elsewhere; the design favors clarity and convenience over deep, room-filling low end. Also, buyers who need waterproof or outdoor-rated speakers should consider different options.

Pros & Cons

Pros

• Clear voice reproduction that improves dialogue intelligibility for movies and TV.
• Compact, ultra-slim profile that fits easily under TVs and in tight spaces.
• Wireless Dolby Atmos and simple pairing reduce cable clutter while delivering immersive sound.
• Seamless integration with Samsung TVs through Q-Symphony for enhanced multi-speaker performance.

Cons

• Sound quality and power are mixed in feedback, and the unit may not satisfy listeners who want very loud or bass-heavy performance.
• Not waterproof and not intended for outdoor use or very large rooms.

Our Verdict

The Samsung S700D 3.1ch soundbar is a smart choice for buyers who value a slim, unobtrusive unit that improves dialogue clarity and adds spatial Dolby Atmos effects without wiring complexity. It is best for small to medium rooms and Samsung TV owners who will benefit from Q-Symphony; for those wanting deeper bass or very high volume the S700D is a convenient, good-value midrange option but not a full replacement for larger home theater systems.
