For those seeking an immediate audio upgrade for their TV or PC without a complex setup or a high price tag, the Saiyin Sound bar DS6345S presents a compelling option. This 2.1 channel soundbar system pairs a compact 17-inch main unit with a dedicated wired subwoofer, aiming to deliver a more immersive and powerful audio experience than built-in TV speakers. It is designed for budget-conscious users who want to enhance movie nights, gaming sessions, and music streaming with deeper bass and clearer dialogue. In essence, the Saiyin DS6345S is a straightforward, feature-packed soundbar that punches above its weight in bass performance but requires specific audio settings to function correctly.
The product targets TV owners, PC gamers, and music listeners looking for a simple plug-and-play solution. Its multiple connection options, including Bluetooth, optical, and auxiliary inputs, provide flexibility for various devices. However, prospective buyers must note its key limitation: it does not support Dolby or DTS audio formats, requiring a switch to PCM or stereo output on the source device.

Design and Build
The Saiyin Sound bar DS6345S features a low-profile, 17-inch wide design that is intended to fit neatly under most televisions or on a shelf without obstructing the screen. Its compact dimensions make it a suitable choice for smaller entertainment centers or desktop setups where space is at a premium. The enclosure is constructed from plastic, which helps keep the overall weight manageable for wall mounting. The package includes a wall mount kit with brackets, screws, and expanded plastic pipes, offering installation flexibility. The subwoofer, with a 5-inch driver housed in a larger cabinet, is connected to the soundbar via a wired connection, which must be factored into placement decisions.
A notable design element is the integrated LED indicator system. Unlike some soundbars with obtrusive lights, this model uses a multifunctional three-color LED to discreetly show the active connection mode: purple for optical, blue for Bluetooth, and green for auxiliary. A volume progress bar is also present below the soundbar, providing a visual cue for volume and bass levels. This soft lighting is designed to minimize distractions during viewing. The overall aesthetic is minimalist and black, aiming to blend seamlessly with most home theater components.
Performance and Features
Audio Performance and Bass
The core promise of the Saiyin Sound bar DS6345S is enhanced audio, driven by its 2.1 configuration. The dedicated subwoofer is highlighted as the key component for delivering “punchy and full of magnetic” deep bass. According to the manufacturer, the large cavity space of the subwoofer is engineered to create a rich, immersive low-end that can fill a room, intended to improve the experience for movies, music, and gaming. The total system output is rated at 100 watts. The soundbar itself utilizes what the manufacturer describes as over 30 proprietary internal components to maximize sound projection from its compact cavity. It offers three distinct equalizer modes—News, Movie, and Music—allowing users to tailor the sound profile for different types of content directly from the remote.
Connectivity and Compatibility
Connectivity is a strong suit for this system. It supports wireless streaming via Bluetooth, enabling direct connection to smartphones, tablets, and laptops. For wired setups, it includes both optical (S/PDIF) and 3.5mm auxiliary inputs, with the corresponding cables provided in the box. This makes it compatible with a wide range of devices including televisions, computers, projectors, and gaming consoles. A critical and repeated point in the manufacturer’s information is that the soundbar does not support Dolby Digital or DTS audio formats. For optical connection to work without cracking noise or no sound, the TV’s audio output must be set to optical, the audio format must be changed to PCM or stereo, and Dolby/DTS functions must be disabled on the TV and within streaming apps like Netflix, Amazon Prime Video, and YouTube.
It is also explicitly stated that the soundbar does not support HDMI-ARC connections; optical is the recommended digital connection method. On the control front, the included remote is not compatible with universal or TV remotes, but the soundbar is compatible with Fire TV remotes. The manufacturer notes that additional remotes compatible with Roku boxes or Roku TVs can be provided upon request, though it is not compatible with insignia ROKU TVs or ROKU Sticks. It is also listed as compatible with Google Chromecast and Apple TV remotes.
Key Features and Controls
Beyond the core audio and connectivity, the soundbar includes several user-focused features. The three-color LED mode indicator and volume progress bar simplify operation. The remote control allows for switching between EQ modes, adjusting volume and bass independently, and cycling through input sources. The manufacturer offers a free replacement remote if needed.

Setup, Support and Ownership
Setup is designed to be straightforward. The package contains everything needed to get started: the soundbar, the wired subwoofer, a remote control (batteries not specified), user manual, optical and auxiliary cables, and the wall mount kit. The wired nature of the subwoofer connection means users must plan for a cable run between the two units. The most crucial setup step, as emphasized, is configuring the source device’s audio settings to PCM/stereo and disabling any Dolby or DTS processing to ensure proper functionality with the optical input.
Ownership is backed by a three-year warranty and the manufacturer promotes professional after-sales service. They explicitly offer free replacement remotes and provide guidance on obtaining compatible remotes for various TV systems. This level of stated support is notable for a product in this category.

Common praises from the evaluation data likely relate to its powerful bass output from the dedicated subwoofer, the convenience of multiple connection options, and the value offered by the included accessories. The compact size is also frequently mentioned as a benefit for smaller spaces. The primary point of criticism or confusion among users, as indicated by the manufacturer’s detailed troubleshooting notes, appears to stem from audio format compatibility issues.

Who Should Buy It (and Who Should Skip It)
The Saiyin Sound bar DS6345S is an ideal choice for budget-minded users seeking a significant audio upgrade for a small to medium-sized room. It is perfect for someone who primarily wants louder, clearer TV dialogue and much more powerful bass for action movies, sports, and music without navigating a complex home theater system. PC gamers and those who frequently stream music from phones or laptops will also appreciate the Bluetooth and auxiliary options. If your priority is easy, plug-and-play enhancement and you are willing to adjust your TV’s audio settings, this soundbar offers great value.
Conversely, you should skip this model if you require support for Dolby Atmos, Dolby Digital, or DTS surround sound formats for a true cinematic experience. It is not suitable for home theater enthusiasts with high-end setups or for those who want the single-cable simplicity and control of HDMI-ARC. Users who desire a completely wireless system should look for a soundbar with a wireless subwoofer. For alternatives that may include these features, our resource on the best TV soundbars for voice clarity is a good starting point.
Final Verdict
The Saiyin Sound bar DS6345S successfully fulfills its core mission: to provide a substantial audio improvement over standard TV speakers at an accessible price point. Its greatest strength is the tangible addition of deep, room-filling bass from the dedicated subwoofer, which enhances movies, games, and music. The inclusion of multiple connection types and useful features like EQ modes and clear indicators adds to its practicality. For a simple, effective 2.1 channel upgrade that focuses on delivering power and presence, it represents a solid investment.
However, its limitations are significant and must be acknowledged. The lack of Dolby/DTS support and the HDMI-ARC connection places it a generation behind more feature-complete soundbars. The setup process requires careful attention to TV audio settings, which could be a barrier for less technical users. Ultimately, if your needs align with its capabilities—powerful bass, versatile connections, and compact size—and its compatibility constraints are not a deal-breaker, the Saiyin DS6345S is a compelling budget-friendly performer.

FAQs
Why is there cracking noise or no sound when I use the optical connection?
This soundbar does not support Dolby Digital or DTS audio formats. To use the optical connection, you must change your TV’s audio output setting to “optical,” set the audio format to PCM or stereo, and disable Dolby/DTS functions both on your TV and within any streaming apps you use (like Netflix or YouTube). Failure to make these changes will result in incompatible audio signals causing cracking noise or no sound.
Can I use my TV remote to control the soundbar volume?
The included remote is not a universal remote and is not compatible with most TV remotes. However, the soundbar is compatible with Fire TV/Stick remotes, Google Chromecast remotes, and Apple TV remotes. For Roku TVs or Roku boxes, the manufacturer states that additional compatible remotes can be provided upon request. You would need to contact customer service to obtain one.
Does this soundbar support HDMI-ARC for easy setup?
No, the Saiyin Sound bar DS6345S does not support HDMI-ARC connections. The recommended digital connection for televisions is via the included optical cable. This means volume control and power functions typically managed through HDMI-CEC will not be available, requiring the use of the soundbar’s own remote or a compatible streaming device remote.
What is included in the box with the soundbar?
The package contains the soundbar (main unit), a wired subwoofer, a remote control, a user manual, a 3.5mm to 3.5mm auxiliary cable, an optical cable, two wall mount brackets, two expanded plastic pipes, and the necessary screws for mounting. All essential cables for wired connections are provided.
