Overview

The BESTISAN S9920 40-Inch Soundbar sits squarely in the entry-level market, designed for anyone tired of thin, tinny TV audio but not ready to spend big on a home theater system. BESTISAN is a brand from MEGACRA Limited, a manufacturer you may not recognize by name, but with over 12,000 Amazon ratings on this model alone, real buyers have clearly put it through its paces. It won't satisfy a dedicated audiophile, but that's not the point. For a budget living room upgrade, it punches meaningfully above the flat speakers built into most mid-size TVs, and that's exactly the promise it delivers on.

Features & Benefits

Six drivers — four 3-inch full-range units flanked by two 2.25-inch tweeters — spread sound across the full 40-inch bar, which helps fill a medium-sized room without the audio feeling pinched or center-heavy. Connectivity is genuinely flexible: optical, stereo RCA, 3.5mm aux, and Bluetooth 5.0 cover nearly every TV or device you'd realistically connect. Three DSP modes let you switch between Movie, Music, and Dialogue tuning depending on what's playing, and you can manually adjust bass and treble on top of that. The bar is wall-mountable, and hardware is included in the box. An 18-month warranty with lifetime technical support adds real peace of mind for a value-tier purchase.

Best For

This soundbar makes the most sense for first-time soundbar buyers upgrading from built-in TV speakers, particularly those with a 40- to 55-inch TV who want a bar that visually matches their screen width. The setup is genuinely simple — no receiver, no app, no complicated pairing ritual. Renters will appreciate the wall-mount option that avoids bulky furniture placement. Casual Netflix watchers, weekend gamers, and anyone who struggles to catch dialogue clearly will notice an immediate improvement. It's not the right fit for people expecting deep, chest-thumping bass without a separate subwoofer, but for everyday streaming use, it covers the basics well.

User Feedback

Most buyers highlight easy out-of-box setup and a clear, immediate improvement over TV speakers as the biggest wins. The optical input is frequently called out as the best-sounding connection, so it's worth using that over Bluetooth if your TV supports it. On the downside, the remote has received consistent criticism for being finicky — sometimes requiring multiple button presses to register. Bass at maximum levels can get boomy and lose definition, so most users land around 60–70% for a cleaner sound. Bluetooth range in larger rooms draws mixed opinions. On durability, a notable number of reviewers mention one to two years of trouble-free use, which is reassuring for the price point.

Pros

  • Immediate, noticeable improvement over flat TV speakers right out of the box.
  • Setup takes minutes — plug in the optical cable and it just works.
  • Three DSP sound modes let you tailor audio to movies, music, or dialogue without an app.
  • Comes with all necessary cables and wall-mount hardware included in the box.
  • The 40-inch width aligns visually with most mid-size televisions for a clean, proportional look.
  • Bluetooth 5.0 pairs quickly and holds steady in normal living room conditions.
  • 18-month warranty is longer than most competitors offer at this price point.
  • Manual bass and treble adjustment adds useful fine-tuning beyond the DSP presets.
  • Multiple wired inputs — optical, RCA, and 3.5mm — cover a wide range of devices including older TVs.
  • Many owners report one to two years of reliable, trouble-free daily use.

Cons

  • The remote frequently requires precise aiming or repeated presses before the bar responds.
  • Bass becomes bloated and loses definition when pushed toward maximum levels.
  • No HDMI ARC input limits compatibility with modern smart TV audio setups.
  • Bluetooth range underperforms in larger rooms or open-plan spaces despite the advertised spec.
  • The plastic end caps feel noticeably cheaper than the metal housing up close.
  • No subwoofer output means low-end depth cannot be expanded later.
  • Bass adjustment increments are too coarse for meaningful fine-tuning at the upper range.
  • A minority of units have shown early hardware failures within the first six months of use.
  • The included audio cable length is short and may not reach in some entertainment center configurations.

Ratings

The BESTISAN S9920 40-Inch Soundbar has accumulated thousands of verified purchases worldwide, and our AI rating system has analyzed that real-world feedback in depth — filtering out incentivized reviews, spam, and outlier noise to surface what genuine buyers actually experience. Scores reflect both the strengths that make this bar a popular first upgrade and the recurring frustrations that keep it from competing with pricier alternatives. Nothing is glossed over.

Value for Money
91%
For buyers stepping up from flat TV speakers for the first time, the price-to-performance ratio consistently earns praise. Reviewers frequently note they expected much less and came away genuinely surprised by the audio improvement, especially when watching movies or streaming shows in the evening.
A small segment of buyers who compared it directly against similarly priced competitors felt the gap was narrower than expected, particularly once they factored in the lack of HDMI ARC support, which some found limiting depending on their TV setup.
Sound Quality
78%
22%
Dialogue clarity stands out as a genuine strength — voices cut through clearly during TV shows and films, which is exactly what most buyers are after. The six-driver setup provides a noticeably wider soundstage than a TV's built-in speakers, and the three DSP modes give users meaningful control over the listening experience.
At higher volumes, the bass can lose precision and start to sound bloated, particularly on action-heavy content. Without a dedicated subwoofer, low-frequency depth has a ceiling, and listeners expecting room-filling bass from this bar alone will likely feel underwhelmed.
Ease of Setup
93%
Setup is one of the most consistently praised aspects across thousands of reviews. Buyers report being up and running within minutes — plugging in the optical cable, powering on, and having it work immediately without fiddling through app configurations or pairing rituals.
A handful of users with older TVs noted minor confusion around input switching, and a few mentioned the included manual could be clearer on which input mode corresponds to which physical connection. These are edge cases, but worth flagging for less tech-savvy buyers.
Remote Control
54%
46%
The remote keeps things simple, covering volume, input switching, DSP mode selection, and bass adjustment without an overcrowded button layout. For straightforward day-to-day use, most buyers find it functional enough to handle the basics without needing to get up from the couch.
Sensitivity issues are one of the most frequently cited complaints. Many reviewers describe needing to point the remote at a precise angle or press buttons multiple times before the bar responds. Over time, this becomes genuinely irritating, and a few buyers resorted to using their TV remote exclusively.
Bluetooth Performance
71%
29%
Bluetooth 5.0 provides a noticeably stable connection in normal living room conditions — pairing is quick, and for rooms under 25 feet or so, dropout complaints are minimal. Streaming music from a phone or tablet works reliably for most users in standard apartment and house layouts.
In larger open-plan spaces or rooms where the phone is moved around frequently, several reviewers reported intermittent dropouts. The real-world range falls short of the advertised 33 feet in some environments, which is a common complaint across Bluetooth audio products in this tier.
Build Quality
69%
31%
The metal housing gives this 40-inch sound bar a sturdier feel than you might expect at this price point. It doesn't flex or creak when handled, and the matte finish resists fingerprints reasonably well, making it look tidy on a TV stand or wall-mounted above a console.
The plastic end caps and some of the smaller assembly details feel noticeably less refined up close, and a few long-term users have reported cosmetic wear around the input panel after a year or more of use. It looks fine from a normal viewing distance, but it's not a premium-feeling object.
Input Variety
83%
Having optical, stereo RCA, 3.5mm aux, and USB all on one bar covers most real-world connection scenarios without needing an adapter. Buyers with older televisions especially appreciate the RCA option, which many competing bars in this range have quietly dropped.
The absence of HDMI ARC is a legitimate gap for buyers with modern smart TVs that are built around that standard. It's not a dealbreaker for everyone, but users who wanted a single-cable audio and control connection via HDMI will need to work around it.
Dialogue Clarity
86%
The dedicated Dialogue DSP mode is frequently called out by buyers who watch a lot of news, talk shows, or drama series where speech intelligibility matters. It makes a real, noticeable difference compared to most TV speakers, particularly at moderate listening volumes in the evening.
At high volumes, the clarity advantage starts to diminish, and some users find the Dialogue mode can make the overall sound thin when there is also a music-heavy soundtrack playing. It works best as a targeted mode rather than a permanent setting.
Wall Mount Design
81%
19%
Wall-mounting hardware ships in the box, which is a practical touch that avoids an extra purchase. The slim 4-inch depth sits close to the wall cleanly, and at 40 inches wide it aligns well visually beneath most mid-size televisions without looking disproportionate.
A couple of reviewers noted the mounting template in the manual was slightly imprecise, requiring minor adjustments during installation. The bar itself is close to 9 pounds, so wall anchoring into studs is recommended — drywall anchors alone make some buyers uneasy over time.
Bass & Treble Adjustment
73%
27%
Having manual bass and treble control on top of the DSP presets is a genuine plus that many bars in this price range skip entirely. It lets users fine-tune the sound to their room acoustics and personal taste without being locked into factory defaults.
The adjustment range is limited — you get incremental steps rather than a full EQ curve, and the bass boost in particular tends to introduce distortion before you reach its maximum. Most users land at a midpoint setting and leave it there rather than experimenting extensively.
Longevity & Reliability
77%
23%
A notable portion of reviewers who have owned this soundbar for one to two years report no hardware failures or degradation in sound output. For a value-tier product, that kind of real-world durability record is meaningful and suggests the internals are at least competently assembled.
There is a smaller but consistent cluster of reviews reporting unit failures within the first six months — occasional power cut-outs or input ports becoming unresponsive. The 18-month warranty covers this window, but the inconsistency in long-term reliability is worth acknowledging.
Warranty & Support
79%
21%
The 18-month warranty is longer than the standard one-year coverage most competitors offer at this price, and the promise of lifetime technical support gives buyers a meaningful safety net. Several reviewers confirmed that customer service responded promptly when issues were raised.
Support quality appears to vary depending on when and how buyers make contact, with a handful of users reporting slow email response times. The warranty process itself is workable, but it requires proof of purchase and can take some back-and-forth before a resolution is reached.
Volume & Room Filling
74%
26%
For a bedroom or medium living room, this 40-inch sound bar puts out enough volume to fill the space comfortably without distortion at moderate levels. Buyers in apartments consistently note it reaches a perfectly usable loudness without bothering neighbors when kept under around 70 percent.
In larger open-plan living areas or rooms with high ceilings, the bar starts to feel underpowered at the upper end of its range. Without a paired subwoofer, the low-end support that helps audio feel full in big rooms simply isn't there.
Packaging & Included Accessories
82%
18%
The box includes an optical cable, audio cable, remote, power adapter, and wall-mount hardware — a complete package that means most buyers don't need to order anything extra to get started. Reviewers frequently mention this as a pleasant surprise compared to brands that ship the bar alone.
The included remote batteries are standard AAA cells that some buyers found depleted after only a few weeks of regular use. The audio cable length is also on the short side for certain entertainment center configurations, occasionally requiring buyers to rearrange their setup.

Suitable for:

The BESTISAN S9920 40-Inch Soundbar is an excellent fit for anyone making their first real upgrade from a flat-screen TV's built-in speakers and not looking to spend a lot doing it. If you have a 40- to 55-inch television in a living room or bedroom and just want noticeably better dialogue clarity and fuller movie audio without wiring up a full receiver system, this bar delivers exactly that. Renters and apartment dwellers will appreciate that it comes with wall-mount hardware included, making installation straightforward without committing to a permanent furniture arrangement. Casual streamers who spend most evenings watching dramas, news, or comedies will find the Dialogue DSP mode particularly useful — voices become cleaner and easier to follow at lower volumes, which matters if you're watching late at night. Gamers on a budget who want more immersive audio than their TV offers, without the complexity of a surround setup, will also get solid value here.

Not suitable for:

If you're expecting deep, physical bass from this bar on its own, you're likely going to be disappointed — without a dedicated subwoofer, low-frequency impact has a real ceiling, and no amount of bass adjustment fully compensates for that. Buyers with newer smart TVs built around HDMI ARC for single-cable audio control will hit a frustrating limitation, since the BESTISAN S9920 40-Inch Soundbar doesn't include that input, requiring a workaround via optical or aux instead. Anyone who streams audio wirelessly from a device on the far side of a large open-plan room may run into Bluetooth inconsistency, as real-world range falls short of the spec in less-than-ideal conditions. Home theater enthusiasts who already own or plan to buy a subwoofer and rear speakers should look at a more expandable system rather than treating this as a foundation to build on — it isn't designed for that. And if a finicky remote will drive you up the wall, be warned: it's one of the most consistent complaints from long-term owners.

FAQ

It works with virtually any TV that has at least one of the following outputs: optical, RCA, or 3.5mm aux. Since there is no HDMI ARC port, you will need to use one of those wired connections or pair wirelessly via Bluetooth. Brand does not matter — if your TV has one of those outputs, you are good to go.

Most users who have tested multiple inputs consistently prefer the optical connection for the cleanest, most stable audio. Bluetooth is convenient but introduces a small amount of compression that can be noticeable on music. If your TV has an optical output, that is the connection to use first.

Setup is genuinely straightforward. Connect the optical cable from the bar to your TV, plug in the power adapter, switch the bar to the correct input using the remote, and audio will come through. Most people are up and running in under ten minutes without needing to read the full manual.

Yes, Bluetooth 5.0 is built in, so you can pair your phone or tablet directly and stream music wirelessly. Pairing works like any standard Bluetooth speaker — hold the Bluetooth button, find the device on your phone, and connect. In normal room conditions, the connection is stable and dropout-free.

This is a known issue that several owners have flagged. First, check that you are pointing the remote directly at the front panel of the bar, as the IR receiver has a narrow acceptance angle. Replacing the batteries early — even if they seem fine — resolves the issue for many users. If problems persist, BESTISAN customer support can advise further or arrange a replacement under warranty.

For everyday TV watching, dialogue-heavy shows, and moderate movie viewing, the built-in bass is perfectly acceptable. However, if you regularly watch action films or listen to bass-heavy music and want physical, chest-level low-end impact, you will likely notice its limits. There is no subwoofer output on this bar, so it cannot be expanded in that direction later.

No, the BESTISAN S9920 40-Inch Soundbar is a standalone 5.0-channel bar and is not designed to integrate with external amplifiers or home theater receivers as a centre channel. It is a self-contained unit intended for direct TV connection rather than as a component in a wider system.

The box includes mounting brackets and a template that you hold against the wall to mark drill points. For most walls, the process takes about 20 to 30 minutes with a drill and a level. It is worth mounting into studs or using appropriate wall anchors rated for at least 15 pounds, since the bar weighs just over 9 pounds and you want a secure fit long-term.

Yes, the bar retains the last active input setting when powered off and on again, which means you do not need to reselect your preferred input every time you use it. The same applies to volume and DSP mode, saving you from resetting preferences each session.

BESTISAN provides an 18-month full warranty, which covers manufacturing defects and hardware failures. Reaching their support team via the contact information included in the box or on their product page is the fastest route. Most users who have needed warranty service report the process is workable, though email response times can vary. The lifetime technical support promise also means you can get guidance on setup or troubleshooting issues even after the warranty window closes.
