The BESTISANAudioSpeakers S6520M is a 28-inch model designed specifically for this purpose, targeting users in bedrooms or apartments who need a space-saving audio boost.

Design and Build
The BESTISAN S6520M adopts a minimalist, rectangular bar design measuring 28 inches in length, which allows it to sit discreetly below most televisions without overwhelming the space. Its 4-inch height and depth contribute to a low-profile look suitable for bedrooms and apartments where space is at a premium. The build is designed for flexible placement; it can rest flat on a TV stand or be securely mounted on the wall using the included accessories, offering users a choice to integrate it cleanly into their existing setup. The unit is finished in black, a standard color that blends with most home theater components. The construction appears focused on practicality, with ports and controls logically arranged for easy access during setup.
Performance and Features
Audio Output and Modes
At the heart of the S6520M’s performance are its two 3-inch full-range drivers and dual bass ports, which the manufacturer states are responsible for delivering enhanced, room-filling sound. The soundbar employs Digital Signal Processing (DSP) to offer three distinct equalizer modes: Movie, Music, and Dialogue. These modes are designed to optimize the audio profile for specific content—boosting effects and bass for films, enhancing clarity and range for music, and prioritizing vocal frequencies for television shows and podcasts. The remote control allows for on-the-fly switching between these modes and also provides separate bass and treble adjustment, giving users a degree of fine-tuning to match their listening preferences or room acoustics.
Connectivity and Ports
Versatility in connection is a major selling point for this soundbar. It supports both wired and wireless audio sources comprehensively. For modern televisions, the HDMI ARC (Audio Return Channel) port is a key feature, allowing for a single-cable connection that can carry high-quality audio from the TV to the soundbar and also enable control via the TV remote. An optical input serves as an alternative for older TVs. Wireless connectivity is handled by Bluetooth 5.0, praised in the data for being “ultra fast and stable,” enabling easy streaming from smartphones, tablets, or laptops. Additional ports include a 3.5mm AUX input, a USB port for playing media files, and a dedicated subwoofer output for those who wish to add an external sub for deeper low-frequency effects.
Key Features and Technology
Beyond the core audio hardware, the BESTISAN S6520M incorporates several features aimed at user convenience and enhanced performance. The inclusion of CEC (Consumer Electronics Control) function via HDMI allows compatible TVs and devices to be controlled together. The DSP technology is cited as working to provide clear, distortion-free audio even at higher volumes. The product specifications list it as supporting a 5.1 channel surround sound output mode, suggesting it can process multi-channel audio signals, though it physically houses only the left and right channels in the single bar. The ability to adjust bass directly is highlighted as a key feature, addressing a common desire for more customizable audio from compact systems.
Setup, Support and Ownership
Setup is described as simplified, with the package including the necessary cables (optical and audio), a power adapter, remote control, user manual, and wall-mount accessories. Owners note that mounting is straightforward, though care must be taken to align the bar correctly with the wall bracket. The manufacturer provides a 12-month after-sales support warranty. A notable aspect of ownership is the potential for expansion; the dedicated subwoofer output port allows users to connect a compatible active subwoofer at a later date, customizing the bass response to their liking. For TV setups, some configuration on the television itself may be required, such as setting the audio output to PCM format for certain connections, a detail mentioned in the product data.
What Owners Say
Owner feedback for the BESTISAN S6520M is overwhelmingly positive, reflected in its high average rating. The vast majority of reviewers award it five stars, with a significant portion giving four stars. Common praises highlight the dramatic improvement over built-in TV speakers, with specific mentions of clear dialogue, surprisingly strong bass for its size, and a full, balanced sound that eliminates the “tin can” quality of cheaper alternatives. Many owners appreciate the easy setup and the multiple connection options, particularly the reliability of the Bluetooth 5.0 connection. Several reviews directly compare it favorably to other budget soundbars, noting its superior tonality and sound quality. Critical feedback from lower-star reviews occasionally mentions issues like a missing mounting screw in the box or notes that while the bass is good for its size, it can distort at maximum volume in larger spaces, and the unit lacks a built-in subwoofer for the deepest lows.

Who Should Buy It (and Who Should Skip It)
The BESTISANAudioSpeakers S6520M is an ideal choice for users in smaller living spaces like bedrooms, apartments, or dorm rooms who are frustrated with their TV’s weak built-in audio. It’s perfect for those who want a simple, single-cable (HDMI ARC) or wireless (Bluetooth) setup without the complexity of a full surround sound system. Viewers who prioritize clear dialogue in TV shows and movies, as well as casual music listeners, will find its performance more than adequate. It also suits anyone looking for a budget-friendly first step into improved home audio, with the option to add a subwoofer later.

Conversely, those with large living rooms or home theaters seeking earth-shaking, theater-quality bass and a truly immersive, multi-directional soundstage should look elsewhere, likely to systems that include a separate subwoofer and satellite speakers. Audiophiles demanding pristine, high-fidelity music reproduction may also find the limitations of this budget soundbar too constraining. If your primary need is for a portable Bluetooth speaker for outdoor use, this is not the right product.
Final Verdict
The BESTISAN S6520M soundbar successfully fulfills its core mission: to provide a substantial and hassle-free audio upgrade for television viewing in compact spaces. Its strength lies in its straightforward value proposition—offering markedly better sound quality than TV speakers, a very flexible set of inputs and outputs, and useful customization through EQ modes and bass adjustment. The positive consensus from thousands of owners validates its performance in real-world settings, particularly for enhancing dialogue and providing a fuller sound for movies and music.
However, it operates within the inherent constraints of a compact, single-enclosure design at its price point. The lack of a built-in subwoofer means it cannot produce the deepest cinematic rumbles, and pushing it to extreme volumes in large rooms may reveal its limitations. For those seeking a simple, effective, and affordable solution to poor TV audio, it represents a compelling choice.

FAQs
Can I connect a subwoofer to the BESTISAN S6520M?
Yes, the soundbar features a dedicated subwoofer output port. This allows you to connect a compatible active subwoofer (purchased separately) to enhance the low-frequency bass response, which is a common upgrade path for users who want more powerful lows than the built-in drivers can provide.
What is the difference between the Movie, Music, and Dialogue sound modes?
These are three preset equalizer modes accessible via the remote control. Movie mode is designed to boost sound effects and bass for a more immersive film experience. Music mode tailors the frequency response for better clarity and range across musical genres. Dialogue mode prioritizes vocal frequencies, making speech in TV shows, news, and podcasts clearer and easier to understand.
Does it work with any TV?
The soundbar is compatible with most televisions thanks to its multiple connection options. For modern TVs with an HDMI ARC port, this is the recommended single-cable connection. For older TVs, you can use the included optical cable or the 3.5mm AUX input. The product data notes that for some TV setups, you may need to access your TV’s audio settings and change the output format to PCM for proper functionality.
How do I mount it on the wall?
The product includes wall-mount accessories (brackets and screws). The manual provides instructions, and owner reviews suggest the process is straightforward. A tip from users is to ensure you insert the correct end of the soundbar into the wall mount first for easier alignment. Always ensure you are mounting into a stud or using appropriate wall anchors for a secure installation.
