Design and Build
The OXS 80-Watt soundbar features a straightforward, modern black design intended to blend seamlessly with most home entertainment setups. Its build is focused on practicality, offering users a choice between placing it on a TV stand, cabinet, or mounting it directly on the wall to save space. This flexibility is a key selling point for those with limited surface area or who prefer a clean, installed look. The inclusion of a light guide on the unit itself is a thoughtful touch, providing clear visual feedback for connection status and the active equalizer mode, which aids in setup and daily use without needing to reference a manual constantly.
Stylistically, it opts for a minimalist aesthetic that doesn’t draw attention away from the screen. The construction details regarding specific materials or dimensions are not listed by the manufacturer, but the design philosophy is clearly centered on versatility and user-friendly operation. The ability to wall-mount adds to its appeal as a permanent living room fixture, while its compact form factor ensures it won’t dominate your entertainment center if placed on a stand.
Performance and Features
Audio Performance and Modes
The core promise of the OXS 80-Watt is enhanced audio performance over standard TV speakers. It delivers a total of 80 watts of power through four full-range drivers. A significant highlight is the Enhanced Dialogue Technology, which is engineered to make vocal details stand out clearly, a common pain point with built-in TV audio and even some soundbars. This is supported by a claimed total harmonic distortion of less than 1%, suggesting cleaner sound reproduction at its price point.
For tailoring sound to different content, the soundbar offers three preset equalizer modes accessible via the included remote or buttons on the unit: Movie mode, Music mode, and a combined News/Game mode. The Movie mode is designed to leverage the built-in DSP technology to create a cinematic 3D surround sound experience, using a special port tube reflection to achieve what OXS calls “dynamic bass.” The Music mode is tuned for higher quality music playback, while the News/Game mode likely focuses on clarity for speech and precise audio cues.

Connectivity and Ports
Connectivity is a major strength of this model. It supports wireless streaming via Bluetooth 5.0, allowing for easy connection to smartphones, tablets, and laptops for playing music. On the wired side, it is exceptionally versatile, featuring optical, coaxial, and standard 3.5mm AUX inputs. This wide array of options ensures compatibility with nearly any television, desktop PC, or gaming console on the market. It also includes a USB port for playing audio files directly from a flash drive.
A crucial setup note provided by the manufacturer is that for optical or coaxial connections, the connected TV or source device must have its audio output format set to PCM. This is a common requirement for soundbars without advanced audio decoders and is a step some users may need guidance on, as outlined in the product details. This level of connectivity makes it a flexible hub for various audio sources in a living room or bedroom.
Setup, Support and Ownership
Setup is designed to be straightforward, with multiple connection paths and a remote control for operation. The most notable requirement is the need to manually configure the TV’s digital audio output to PCM when using the optical or coaxial inputs, a process the manufacturer provides steps for. Once configured, the soundbar should function as a plug-and-play device. The inclusion of a remote and status lights aids in daily ownership, making it simple to switch between inputs and sound modes.
Information regarding long-term software updates, warranty specifics, or accessory options like separate subwoofers or satellite speakers is not provided in the available data. The product appears to be a standalone, all-in-one solution. Support would be handled through OXS’s standard customer service channels. The design suggests a low-maintenance ownership experience focused on simple audio enhancement without complex calibration or system expansion.
What Owners Say
Overall owner feedback for the OXS 80-Watt soundbar is positive. Users generally report a significant and noticeable improvement over their television’s native speakers, with particular praise for the clarity of dialogue, which aligns with the product’s marketed Enhanced Dialogue Technology. The variety of connection options is frequently cited as a major benefit, providing flexibility for different setups. The value proposition is often highlighted, with owners feeling the audio performance justifies the investment.
Some critiques from users touch on the limitations of its bass performance, noting that while it provides a dynamic low-end compared to TV speakers, it may not satisfy those seeking very deep, room-shaking bass. A few users mention the initial setup step involving PCM settings, confirming it as a point that can require extra attention for those unfamiliar with TV audio menus. The general consensus points to a reliable product that delivers on its core promise of clearer, more powerful TV audio for everyday viewing.

Who Should Buy It (and Who Should Skip It)
The OXS 80-Watt soundbar is an ideal choice for budget-conscious viewers who are frustrated with muffled dialogue and weak sound from their TV. It’s perfect for small to medium-sized living rooms or bedrooms where a simple, single-unit upgrade is desired. Users who frequently stream music from their phones or tablets via Bluetooth will appreciate the wireless functionality, and those with older TVs will benefit from the multiple wired connection options. It’s a strong match for anyone seeking a noticeable improvement in TV audio for movies, news, and general entertainment without a complex installation.
This soundbar should likely be skipped by audiophiles or home theater enthusiasts who prioritize deep, powerful bass or object-based surround sound formats like Dolby Atmos. Users with very large, open-concept spaces might find the 80-watt output limiting. Those who want a system they can expand later with a subwoofer or rear speakers should look for models with dedicated wireless outputs. If your primary need is for multi-room audio, you might find dedicated systems more suitable, as explored in our article on the best smart speakers for multiroom audio.
Final Verdict
The OXS 80-Watt soundbar successfully fulfills its mission as an accessible gateway to better TV audio. Its standout feature, Enhanced Dialogue Technology, addresses a common viewer complaint directly and effectively. When combined with the convincing 3D surround sound simulation from its four-speaker array and DSP, it creates a genuinely more engaging and cinematic experience for movie nights. The sheer number of connection ports and Bluetooth 5.0 support ensures it can serve as the central audio hub for nearly any setup, adding significant utility beyond just TV sound.
While it has understandable limitations in maximum output and deep bass extension, these are reasonable trade-offs at this price point. For the vast majority of users looking to solve the problem of poor TV audio with a simple, effective, and versatile solution, the OXS 80-Watt represents a compelling choice. It delivers core performance where it counts—clarity, immersion, and ease of use—making it a recommended option for an affordable home theater upgrade.
FAQs
Does the OXS 80-Watt soundbar come with a subwoofer?
No, the OXS 80-Watt is a standalone soundbar unit. It does not include a separate subwoofer. It uses a port tube reflection design to produce what the manufacturer calls “dynamic bass” from the soundbar itself. There is also no dedicated subwoofer output listed to add one later, so it is designed as an all-in-one solution.
Can I connect this soundbar to my TV wirelessly?
The soundbar features Bluetooth 5.0 for wireless streaming from devices like phones, tablets, and laptops. However, for connecting to your TV, a wired connection (optical, coaxial, or AUX) is required, as it does not support wireless TV audio protocols like Bluetooth audio from the TV itself. The Bluetooth is primarily for streaming music from personal devices.
What does “set audio output to PCM” mean for setup?
This is a required step when using the optical or coaxial digital connections. PCM (Pulse-Code Modulation) is a standard, uncompressed audio format. Many TVs output compressed audio formats like Dolby Digital by default. The OXS soundbar requires the simpler PCM signal. You must enter your TV’s sound settings menu and change the “Digital Output Audio Format” (or similar) setting to PCM for the connection to work properly.
How does the News/Game mode differ from the Movie mode?
While specific frequency curve details are not provided, the modes are preset equalizer settings optimized for different content. Movie mode is tuned to emphasize surround sound effects and cinematic bass. The News/Game mode is likely optimized for clarity, boosting vocal frequencies for understandable speech in news broadcasts and enhancing precise audio cues like footsteps or gunshots in video games, without the heavy bass emphasis of Movie mode.
