TCL S55H vs VastSND Dolby Digital Plus Bar
Quick Verdict
The TCL S55H is the stronger pick for most buyers who want a budget soundbar with Dolby Atmos, a wireless subwoofer, and HDMI eARC. Its up to 220 W power and app-based room calibration justify a score of 74. The VastSND Dolby Digital Plus Bar is simpler and lower scoring at 59. It decodes Dolby Digital Plus and offers three EQ modes plus flexible placement, but lacks a specified subwoofer, eARC, app, and published driver details. Choose the VastSND only if you need a basic Dolby Digital Plus upgrade without a separate sub or future-ready connections. For most TV setups, the TCL S55H is the better rounded value.

Sound Quality
The TCL S55H carries a sound quality score of 22 out of 30 in the listing. It is a 2.1 channel soundbar with a wireless subwoofer included and up to 220 W total power. The listing does not publish driver sizes or frequency response. In comparison, the VastSND Dolby Digital Plus Bar scores 20 out of 30 for sound quality. Its channel configuration and driver sizes are not published, and the listing gives a 110 W total output figure from the title.
TCL's higher power rating and included subwoofer suggest more headroom and deeper bass than the VastSND on paper. The VastSND relies on Dolby Digital Plus decoding and three EQ modes, but without a separate subwoofer it may not match the TCL's low end. Both bars lack published driver details, so a direct comparison of clarity or tonal balance is limited. The sound quality points difference is small, but the TCL's wireless sub gives it a practical advantage.
VastSND's three EQ modes, labeled Movie, Music, and News, let users tailor the sound for different content. The TCL does not list dedicated EQ presets in the supplied facts, though its app can run AI Sonic Auto Room Calibration. The TCL's calibration is designed to adjust sound based on the room, which could improve dialogue and balance in real spaces. For raw power and bass, the TCL S55H appears stronger from the published specifications.
Surround, Atmos and Audio Formats
The TCL S55H scores 10 out of 15 in surround and audio formats because it supports Dolby Atmos and DTS Virtual:X. The listing title also mentions DTS:X, but the breakdown focuses on Atmos and DTS Virtual:X. This means the TCL can process object-based height cues and virtual surround from a 2.1 speaker layout. The VastSND Dolby Digital Plus Bar scores only 5 out of 15. It supports Dolby Digital Plus only, with no mention of Dolby Atmos, DTS, or DTS:X.
Neither soundbar has discrete surround speakers, so both rely on virtual processing or basic stereo plus sub output. The TCL's virtual height and DTS Virtual:X add a sense of space that the VastSND cannot match on paper. The VastSND decodes Dolby Digital Plus, which is an upgrade over standard Dolby Digital but still lacks the object-based format of Atmos. Buyers who watch Atmos content will notice the difference in supported formats.
For TV shows and movies with Dolby Digital Plus soundtracks, the VastSND can still provide a cleaner experience than built-in TV speakers. However, the TCL S55H is more flexible for streaming services that use Atmos or DTS encoded content. The TCL also supports DTS Virtual:X, which can create virtual height and side effects from non-Atmos sources. This gives the TCL a clear advantage in the surround and audio formats category.
Subwoofer and Bass
The TCL S55H includes a wireless subwoofer with dimensions 7.68 inches wide, 12.60 inches high, and 7.68 inches deep. This separate subwoofer is designed to handle low frequencies and take bass load off the soundbar. The VastSND Dolby Digital Plus Bar listing does not specify a separate subwoofer or any subwoofer details. It is not clear from the listing if the VastSND has built-in bass radiators or a subwoofer output.
The TCL's up to 220 W total power, combined with the wireless subwoofer, suggests stronger bass output. The VastSND's 110 W total output, without a specified subwoofer, likely provides less low-frequency impact. Since the listing for VastSND does not publish driver sizes or enclosure details, exact bass performance is unknown. The TCL has a clear paper advantage for buyers who want a dedicated subwoofer.
The wireless subwoofer on the TCL adds placement flexibility, as it does not need a cable run to the soundbar. The VastSND's four setup positions may help with room placement, but that does not compensate for the absence of a separate subwoofer. Buyers who want movie rumble and music bass should note that the TCL S55H is the only model of the two that explicitly includes a subwoofer.
Connectivity and TV Setup
The TCL S55H offers HDMI eARC/ARC, optical, AUX, and Bluetooth. Its connectivity score is 12 out of 15. The listing says it includes one HDMI cable, one power cord, one remote with batteries, and a wall-mount kit. The VastSND Dolby Digital Plus Bar offers ARC only, not eARC, plus optical, AUX, and Bluetooth. Its connectivity score is 10 out of 15.
HDMI eARC on the TCL supports higher bandwidth audio return, including lossless formats like Dolby TrueHD with Atmos. The VastSND's ARC connection is limited to compressed Dolby Digital Plus from compatible TVs. The VastSND listing does not publish included accessories beyond a mention of a manual and tutorial video. It is unclear if the VastSND includes an HDMI cable or remote.
Both models include optical and AUX inputs, which help connect older televisions or external devices. Bluetooth is available on both for wireless music streaming from phones or tablets. The TCL's eARC and included HDMI cable make setup simpler for modern TVs. The VastSND can still connect via ARC, optical, or AUX, but lacks the future-facing eARC port.
Features, Apps and Voice Control
The TCL S55H scores 10 out of 15 for features and apps. It includes a full-function remote and a TCL app for AI Sonic Auto Room Calibration. The listing does not mention Wi-Fi streaming, multiroom audio, or voice assistant support. The VastSND Dolby Digital Plus Bar scores 8 out of 15 for features and apps. It has three EQ modes, Movie, Music, and News, plus four setup positions, but no app, Wi-Fi, or voice assistant is mentioned.
The TCL app adds a useful calibration tool that can tune sound to the listening room. The VastSND's EQ modes are more basic but can be changed without an app, although the listing does not specify a physical remote beyond TV remote control in ARC mode. Neither model supports built-in voice assistants like Alexa or Google Assistant based on the supplied facts. If you want app control and automatic calibration, the TCL is the better equipped model.
The VastSND does not list a companion app, so firmware updates or advanced settings may be unavailable. TCL's app-based calibration could be limited on some phones, as noted in the cons, but it is still an added feature. For users who prefer a simple button or TV remote control, the VastSND may be adequate. The TCL offers more modern convenience features overall.
Design and Fit Under a TV
The TCL S55H soundbar measures 31.89 inches wide, 2.36 inches high, and 3.86 inches deep. This low profile is designed to fit under many TVs without blocking the screen. The included wall-mount kit adds installation options. The subwoofer measures 7.68 inches wide, 12.60 inches high, and 7.68 inches deep, so it needs floor or shelf space.
The VastSND Dolby Digital Plus Bar listing does not publish dimensions for the soundbar. It mentions four setup positions for room flexibility, which suggests it can be placed flat on furniture or perhaps wall mounted, but no mounting hardware is specified. Without dimensions, it is hard to know if the VastSND fits under a particular TV stand. The TCL's published height of 2.36 inches is relatively slim, giving it an edge in this category.
The TCL scores 12 out of 15 in design and TV fit, while the VastSND scores 9 out of 15. The VastSND's flexible positioning may help in unusual spaces, but unknown size is a drawback. The TCL's compact subwoofer is also easier to place than large home theater subs. Buyers with a fixed TV stand should check the TCL dimensions, while VastSND buyers would need to confirm measurements from other sources since the listing omits them.
Who Should Buy It
The TCL S55H is best for buyers who want a budget 2.1 soundbar with Dolby Atmos, a wireless subwoofer, and simple TV connections. It fits households that want a noticeable upgrade from built-in TV speakers without adding separate rear speakers. The room calibration app and eARC support also appeal to those with a newer TV. Its overall score of 74 reflects a balanced feature set for the price.
The VastSND Dolby Digital Plus Bar is best for budget-minded TV owners who want a simple Dolby Digital Plus upgrade with flexible placement options. It may suit older TVs that only have ARC or optical out. The three EQ modes and four setup positions give basic control. Its overall score of 59 is lower because it lacks a subwoofer, Atmos, eARC, and published driver details.
Neither model is for buyers who need true discrete surround speakers or advanced smart features. Both are stereo or 2.1 style bars with virtual processing at most. The TCL is better for a fuller home theater feel on a budget. The VastSND is better for a no-frills audio boost if the price is the main concern.
The Deciding Question
The deciding question is whether you need Dolby Atmos, a wireless subwoofer, and HDMI eARC. If yes, the TCL S55H is the obvious choice. It supports these features and includes an HDMI cable and wall-mount kit. The scoring difference of 74 to 59 confirms the TCL's stronger list of capabilities.
If you only need a basic Dolby Digital Plus soundbar and do not care about a separate subwoofer or eARC, the VastSND may be acceptable. Its 110 W output and three EQ modes can improve dialogue and music for a smaller space. However, the listing omits key details like driver sizes, channels, and dimensions, which makes it harder to recommend with confidence.
Value is also a factor, but since no prices are supplied in the facts, the comparison rests on features. The TCL offers more features for the likely price difference. The VastSND sacrifices future-ready connections and bass depth for a simpler design. Your decision should hinge on how much you value the TCL's subwoofer, Atmos, and eARC over the VastSND's more basic setup.
Who Should Buy Which
Choose the TCL S55H if you want a wireless subwoofer, Dolby Atmos and DTS Virtual:X decoding, and HDMI eARC. It is the better pick for movies, streaming, and music that benefit from low-end energy and virtual surround. The TCL app adds room calibration, which can improve sound in real rooms. Its 220 W power rating and included accessories make it a practical upgrade.
Choose the VastSND Dolby Digital Plus Bar if you have a tight budget, an older TV with ARC or optical, and no need for a separate subwoofer. It is also a fit for users who want three simple EQ modes and flexible placement without dealing with an app or virtual surround formats. Its 110 W output should be enough for a bedroom or secondary TV.
If you are still unsure, consider future TV upgrades. The TCL's eARC and Atmos support will remain useful as you upgrade to a 4K TV with eARC. The VastSND's ARC-only connection may become a limitation. For most buyers comparing these two models, the TCL S55H delivers a more complete soundbar package even though both are entry-level options.
