Design and Build

The Samsung B400 sports a compact and minimalist design, with a width of just over 25 inches. This footprint allows it to sit neatly in front of most television stands without overwhelming the space, making it suitable for smaller rooms, apartments, or bedroom setups. The build is typical of entry-level soundbars, utilizing plastic construction that is lightweight and functional. Its low profile of 2.62 inches helps maintain a clean sightline to the TV screen. While specific materials or premium finishes are not detailed by the manufacturer, the design prioritizes practicality and space efficiency over luxury aesthetics.

The unit is designed for simple placement, but it also offers wall-mounting capability for those who prefer a floating look or need to save surface space. All controls are managed via the included remote control or, notably, through a compatible Samsung television remote, which aligns with the product’s goal of reducing clutter. The physical design is unassuming, putting the focus on its integrated audio components—most importantly, the built-in woofer—rather than on being a visual centerpiece.

Performance and Features

Audio Performance and Built-in Woofer

The core promise of the Samsung B400 is delivering full, balanced sound from a single enclosure. As a 2.0 channel soundbar with a total power output of 40 watts, it is designed to provide a noticeable upgrade over standard television speakers. Its standout hardware feature is the integrated woofer, which aims to produce richer bass without the need for a separate subwoofer box. This design choice saves space, reduces cable clutter, and simplifies setup. For everyday content like TV shows, news, and streaming movies, this configuration is intended to offer robust sound with clearer dialogue and a more immersive low-end presence than a TV can provide alone.

Key software features enhance this performance. The automatic dialogue amplification function is designed to make voices in shows and movies clearer, addressing a common pain point where viewers struggle to hear speech over background music and effects. Additionally, a Night Mode function lowers the overall volume and minimizes bass output, allowing for late-night viewing without disturbing others in the household. The soundbar also mentions a Surround Sound Expansion feature, though specifics on how this is implemented for a 2.0 channel system are not provided in the manufacturer’s data.

Connectivity and Control

Connectivity is a strong suit for the B400, offering multiple ways to link to your devices. The HDMI ARC (Audio Return Channel) port is the recommended connection for modern televisions, as it can carry high-quality audio from the TV to the soundbar and often allows control via a single remote. Optical audio input provides a reliable digital connection for older TVs. Wireless connectivity is handled by Bluetooth, enabling users to stream music directly from smartphones, tablets, or computers. This flexibility makes the soundbar useful for both TV audio and casual music listening.

The most notable control feature is the One Remote capability. For owners of Samsung televisions, the existing TV remote can be used to control key soundbar functions like power, volume, and sound effects. This integration significantly simplifies the user experience by eliminating the need to juggle multiple remotes, aligning with the product’s philosophy of a streamlined setup. A dedicated remote is still included for use with non-Samsung TVs or for accessing all functions.

Power and Compatibility

The Samsung B400 is designed with broad compatibility in mind. Its power supply accepts input voltages from 110 to 240 volts, making it suitable for use in most countries around the world without requiring a separate voltage transformer. This is a practical feature for users who travel or relocate. The soundbar is explicitly compatible with televisions, and its connectivity options ensure it can work with a wide range of models, from newer sets with HDMI ARC to older ones with only optical outputs. The manufacturer states that an HDMI cable is included to facilitate the initial connection, though this has been a point of inconsistency noted in customer feedback.

Setup, Support and Ownership

Setup for the Samsung HW-B400 is designed to be straightforward. The primary method involves connecting a single HDMI cable from the soundbar’s HDMI ARC port to the corresponding port on a compatible TV. For TVs without HDMI ARC, an optical cable (not stated as included) would be used. The Bluetooth pairing process for wireless audio streaming follows standard procedures. The inclusion of a worldwide voltage power supply adds to the plug-and-play nature for most users. The ability to control the soundbar with an existing Samsung TV remote further reduces setup complexity by merging control systems.

In terms of support and ownership, Samsung provides a standard one-year warranty for the product. There is no specific information in the provided data regarding firmware update processes, long-term software support, or official accessory options like dedicated wall mounts. The product is a complete single-unit system; its design with a built-in woofer means there are no separate satellite speakers or subwoofers to add later. Ownership is centered on a simple, maintenance-free experience. For more insights on integrating audio devices into a smart home, you can explore our guide on the best AI smart home devices.

What Owners Say

Owner feedback for the Samsung B400 is generally positive, with a high percentage of favorable ratings. Many users praise the soundbar for being a significant improvement over their television’s built-in speakers, citing good sound quality and easy setup. The value for money is a recurring theme, with owners appreciating the performance delivered at this price point. Several reviews highlight the seamless integration with Samsung TVs and the convenience of using one remote.

The most consistent critical note among reviews pertains to the product description. Multiple owners report not receiving the HDMI cable that is stated to be included, which contradicts the manufacturer’s listing and has caused frustration. Aside from this packaging inconsistency, the primary criticisms relate to the soundbar’s power limitations; some users in larger rooms feel the 40-watt output is insufficient for creating a truly immersive, theater-like volume level. The rating distribution shows a majority of perfect scores, with very few low ratings, indicating overall satisfaction with the core audio performance and ease of use.

Pros and Cons

Pros

  • Excellent value with integrated woofer saving space and cost
  • Seamless control with existing Samsung TV remote
  • Clear dialogue enhancement improves vocal clarity
  • Simple, compact design fits easily into most setups
  • Multiple connectivity options (HDMI ARC, Optical, Bluetooth)
  • Worldwide voltage support for international use

Cons

  • Inconsistent inclusion of the stated HDMI cable
  • 40-watt output may lack power for larger rooms
  • Limited to 2.0 channels without true multi-speaker surround
  • Bass response, while present, is limited by the single enclosure
  • Some may find the sound profile lacks advanced customization

Who Should Buy It (and Who Should Skip It)

The Samsung HW-B400 is an ideal choice for users with Samsung televisions who want a no-fuss audio upgrade. It’s perfectly suited for smaller to medium-sized living rooms, bedrooms, or apartments where space is at a premium and a simple, single-cable setup is desired. Budget-conscious viewers who watch a lot of TV shows, news, and movies and are primarily seeking clearer dialogue and more balanced sound than their TV provides will find great value here. Its features like Night Mode and Bluetooth streaming add everyday practicality.

This soundbar is not the best fit for audiophiles or those with very large living spaces who desire room-shaking, theater-level volume and deep, powerful bass. Users seeking a true discrete surround sound experience with separate rear speakers should look at more advanced systems. Similarly, if having absolute certainty about included accessories is a major priority, the reported inconsistency with the HDMI cable might be a concern. For those prioritizing immersive, multi-channel audio, our roundup of the best surround sound soundbars offers alternatives.

Final Verdict

The Samsung B400 successfully fulfills its mission as a straightforward audio upgrade path. Its integrated woofer delivers a tangible improvement in bass and overall sound fullness over typical TV speakers, while features like dialogue enhancement and Samsung remote integration address real user needs with elegance. The compact size and simple connectivity make it an unobtrusive addition to any entertainment center. While it won’t replace a high-end multi-component system, it offers a compelling blend of performance, convenience, and value for its target audience.

Potential buyers should be aware of the noted inconsistency regarding the included HDMI cable, but this does not detract from the soundbar’s core acoustic performance. For those seeking to enhance their TV’s sound without complexity or significant investment, the Samsung HW-B400 is a highly recommendable option. It exemplifies how thoughtful design and key feature integration can create a product that meaningfully improves the daily viewing experience.

FAQs

Does the Samsung B400 come with a separate subwoofer?

No, the Samsung HW-B400 does not include a separate subwoofer. Instead, it features a built-in woofer within the main soundbar enclosure. This design choice provides enhanced bass compared to standard TV speakers while keeping the setup to a single unit, saving space and eliminating the need for an additional power cable and audio connection for a subwoofer.

Can I control the Samsung B400 with my non-Samsung TV remote?

Yes, you can control the soundbar with a non-Samsung TV remote, but the seamless “One Remote” integration is specifically optimized for Samsung televisions. For other brands, you will likely need to use the dedicated remote control that is included with the soundbar to manage its functions, or you may be able to use your TV’s remote for basic volume control if connected via HDMI CEC, a feature not guaranteed on all TVs.

What is the difference between HDMI and Optical connection for this soundbar?

Both HDMI ARC and Optical connections transmit digital audio from your TV to the soundbar. HDMI ARC is generally preferred as it can support higher-quality audio formats and, crucially, often enables the use of a single remote for both TV and soundbar control via CEC protocols. Optical connections are a reliable fallback for TVs lacking an HDMI ARC port. The Samsung B400 includes both options for flexibility.

Is the Samsung B400 suitable for playing music from my phone?

Yes, the Samsung B400 includes Bluetooth connectivity, allowing you to wirelessly pair your smartphone, tablet, or computer to stream music directly to the soundbar. This makes it a dual-purpose device for both enhancing TV audio and serving as a speaker for casual music listening.
