AI Verdict
This is a major dialogue clarity booster for small-room TVs, but its claims of Dolby Atmos and deep bass are a serious stretch.
This is a strong fit if your main complaint is unclear TV dialogue in a smaller room. It provides a significant upgrade in vocal clarity and overall fullness via a simple HDMI connection. However, it's a weak fit for anyone expecting powerful bass or a convincing surround sound experience, as its 2.0 channel design fundamentally limits its capabilities.
For more impactful bass and a better surround effect, look for a 2.1 or 3.1 channel soundbar that comes with a dedicated wireless subwoofer.

Chance this product isn't for you
Pros
- Dialogue and mid-range sounds are significantly clearer than most built-in TV speakers.
- HDMI eARC connection allows you to control power and volume with your TV remote.
- Supports Dolby Atmos and DTS Virtual:X processing, which widens the soundstage.
- Includes AI Room Calibration, a feature usually found on more expensive models.
- Compact, low-profile design at 31.9 inches wide fits neatly under most small to mid-size TVs.
Cons
- Lacks a dedicated subwoofer, resulting in weak bass that lacks rumble for movies and music.
- The Dolby Atmos effect is virtual and doesn't create a true overhead sound experience.
- Some users report intermittent sound drops or software glitches that require a factory reset.
- The remote is the only way to access certain settings, as they aren't in the app.
Dimension Scores
It offers a clear improvement in dialogue clarity over TV speakers, but the overall sound is unbalanced due to weak bass.
The 100W output is adequate for smaller rooms, but the lack of a subwoofer means bass is present but lacks any real depth or rumble.
It provides a comprehensive set of inputs for its price, including HDMI eARC, Optical, Bluetooth, and AUX.
Users describe the design as sleek and modern, feeling more solid than its entry-level price might suggest.
Best For
- Upgrading the tinny built-in speakers on a bedroom or apartment TV (32-55 inches).
- Users who primarily want to make dialogue in TV shows and movies easier to understand.
- A simple, clean setup using a single HDMI cable for both audio and control.
- Small to medium-sized rooms where high volume and booming bass aren't necessary.
Not Recommended For
- Anyone seeking a true, immersive Dolby Atmos home theater experience with overhead sound.
- Bass lovers who want to feel the low-end rumble in action movies and music.
- Large, open-concept living rooms that require high volume to fill the space.
Watch Out For
- The AI Sonic room calibration requires using the TCL app, which some users might not want to download or use.
- Dolby Atmos is achieved through virtualization, not physical up-firing speakers, so the effect is subtle and won't make sounds come from your ceiling.
- Some users report an audio bug where the soundbar goes mute when switching from Atmos content to stereo, requiring a restart.
- The 'Voice' sound mode can make audio sound compressed or 'tinny'; many users prefer 'Movie' mode for better clarity.
- When connected via HDMI eARC, the soundbar announces the input ("HDMI eARC") out loud every time you turn on the TV, and this can't be disabled.

What Buyers Say
The most noticeable improvement this soundbar makes is with dialogue clarity; voices in movies and shows become much easier to understand compared to muddy TV speakers. While it's marketed with Dolby Atmos, don't expect a theater-like bubble of sound—it's more of a wider, slightly more open stereo field. Most people will use the HDMI ARC connection, which makes setup a breeze and lets you use your existing TV remote for volume. The bass is the biggest compromise; without a subwoofer, it's just not going to give you the rumble you want for action movies. Some owners run into occasional software bugs that cause the sound to drop, often fixed with a simple power cycle or a full factory reset.
“finally i can hear what people are saying in shows without having to turn on subtitles, the bass is pretty meh but for dialogue alone it was worth every penny.”
Common Praise
- Dialogue is significantly clearer and easier to understand.
- Setup is incredibly simple, especially using HDMI eARC.
- It's a huge audio upgrade over the TV's built-in speakers for a low price.
- The bar itself looks sleek and feels more premium than its price tag.
- Works seamlessly with TCL TVs, but is also compatible with other brands.
Common Complaints
- Bass is noticeably weak and lacks deep rumble.
- The 'Dolby Atmos' surround effect is minimal and not very immersive.
- The soundbar loudly announces the input source (e.g., "HDMI eARC") on startup.
- Occasional software glitches can cause sound to drop out or require a reset.
- There's no visual indicator for the current volume level.
Ownership Tips
- You'll likely find a preferred sound mode like 'Movie' and never touch the other presets again.
- The auto power on/off function when connected via HDMI ARC is surprisingly reliable.
- The top-facing indicator lights are hard to see from a seated position, making it tough to know what settings are active.
- After a few weeks, you'll get used to the loud voice prompt at startup, but you'll never like it.
Frequently Asked Questions
Does this soundbar come with an HDMI cable?
Yes, users report that an HDMI cable is included in the box.
Can I add a separate subwoofer to this soundbar?
No, the TCL S45H is a standalone 2.0 channel bar and does not have an output to connect a subwoofer. If you want a subwoofer, you should consider the TCL S55H model.
Is the Dolby Atmos effect noticeable?
The effect is very subtle. It uses virtual processing to create a wider soundstage, but as a 2.0 channel bar without up-firing speakers, it cannot produce true overhead sound.
How do you perform a factory reset if there are issues?
Press and hold the Power, Volume Up, and Volume Down buttons on the soundbar itself for about 10 seconds until the LED flashes. This can fix common issues like sound drops or connection problems.
Will this work with a non-TCL TV?
Yes, it works with any TV brand via HDMI eARC/ARC, Optical, or AUX. Users have reported smooth experiences with various TV brands.
Do I need the app to use it?
You don't need the app for basic operation, but it is required for the AI Sonic Auto Room Calibration feature. Some settings, like surround enhancement levels, can only be adjusted with the remote.
Buying Guide
For a soundbar in this price range, your main goal should be fixing your TV's two biggest problems: unclear dialogue and thin, flat sound. This bar does that well. Don't get fixated on the 'Dolby Atmos' logo on the box. On a 2.0 channel bar like this, it's a processing trick to make the sound feel wider, not a true surround system that bounces sound off your ceiling. Think of it as 'Atmos-lite'.
2.0 Channel Audio
This means the soundbar has two speakers: a left and a right. It's like a much better version of your TV's built-in speakers. It's great for clarity, but it won't give you true surround sound or deep, rumbling bass, which requires more channels and a subwoofer.
Dolby Atmos / DTS Virtual:X
This is software that tries to trick your ears into hearing sound from more than just two speakers. It makes the sound feel bigger and wider than the physical bar, but it's not the same as having actual speakers around you.
HDMI eARC/ARC
This is the best way to connect to your TV. It's a single cable for both audio and control, letting you use your TV's remote to change the soundbar's volume. It's a huge convenience feature that simplifies your setup.
Alternatives
If you want more impactful bass for movies and a more convincing surround experience, search for a '2.1 soundbar' or '3.1 soundbar'. The '.1' in the name signifies that it includes a separate, dedicated subwoofer for low-end frequencies.
