What Exactly Is the TCL S55H?
The TCL S55H is a 2.1-channel home theater audio system consisting of a soundbar and a wireless subwoofer.
TCL, the Chinese electronics brand that has become one of the top-selling TV manufacturers in North America, designed this system to complement its smart TV lineup while remaining compatible with other brands.
The core problem it solves is straightforward: flat-panel TVs have thin profiles that physically cannot house quality speakers.
The S55H fills that gap by adding a dedicated soundbar for midrange and high-frequency audio, plus a separate wireless subwoofer for bass frequencies, without requiring any speaker wire between the two units.
At $139, it sits in the entry-to-mid budget tier. TCL positions this as a step up from their most basic single-bar offerings, targeting buyers who want real bass response and premium audio codec support without moving into the $200-plus range.
How Does the TCL S55H Sound in Practice?
The TCL S55H sounds noticeably better than built-in TV speakers across virtually every content type. Dialogue is clearer, action sequences have more presence, and music playback has genuine depth thanks to the wireless subwoofer.
For movies and streaming content, the Dolby Atmos and DTS:X processing creates a wider, more dimensional soundstage than you’d expect from a two-piece system at this price.
The virtual height effects are subtle rather than dramatic, but they do add a sense of space to soundtracks mixed for Atmos.
Don’t expect the overhead audio separation you’d get from a true multi-speaker Atmos setup, but for a 2.1 system, the processing is well-implemented.
The wireless subwoofer is a genuine highlight. At this price point, many soundbars include subwoofers that feel like afterthoughts, producing muddy or one-note bass.
The S55H’s sub has enough range to make explosions and bass-heavy music feel physical without overwhelming the room.
Customers have described it as delivering “massive punch for the size and price,” and that assessment holds up.
Music performance is competent. Streaming via Bluetooth is clean, and the soundbar handles vocal-forward genres like pop and acoustic well.
Electronic music and hip-hop benefit most from the subwoofer’s output. Classical and jazz listeners may find the tonal balance slightly bass-forward, though the EQ settings can compensate.
For gaming, the system adds directional audio cues that improve immersion in action titles. The low latency Bluetooth mode helps reduce sync issues, though HDMI ARC remains the preferred connection for gaming to avoid any perceptible delay.
What Are the Key Features of the TCL S55H?
Dolby Atmos and DTS:X Support
Both Dolby Atmos and DTS:X are object-based audio formats that encode positional sound information. The S55H processes these formats and uses psychoacoustic techniques to simulate height and surround channels through the soundbar’s driver array.
This is virtual processing, not physical upward-firing drivers, so the effect is more about soundstage width and depth than true overhead audio.
Still, for a $139 system, having both codecs supported is a meaningful feature that ensures compatibility with modern streaming content on Netflix, Disney+, and Apple TV+.
Auto Room Calibration
Room calibration is a feature more commonly found on soundbars costing $300 or more. The S55H includes a microphone-based calibration process that measures your room’s acoustic characteristics and adjusts the EQ and timing accordingly.
In practice, this helps the system sound more balanced in rooms with hard surfaces (which cause reflections) or soft furnishings (which absorb sound). Running calibration takes a few minutes and is worth doing before finalizing your EQ settings.
220W Total System Power
TCL rates the S55H at 220 watts total system power. It’s worth noting that power ratings in consumer audio can be measured in different ways, and peak wattage figures don’t always translate directly to perceived loudness.
That said, the S55H is loud enough to fill a standard living room without straining, and the subwoofer contributes meaningfully to the overall output level.

Wireless Subwoofer
The subwoofer pairs wirelessly with the soundbar, which means no cable running across the floor. The pairing process is automatic in most cases.
Placement flexibility is a real benefit here: you can position the sub in a corner or along a side wall to maximize bass reinforcement.
If you want guidance on optimal placement, our guide on best subwoofer placement with a soundbar covers the key principles in detail.
App Control and Remote
The TCL Home app provides control over EQ settings, sound modes, and firmware updates from a smartphone. The physical remote handles day-to-day volume and input switching.
Some users find the remote straightforward; others report it can be finicky, particularly when the soundbar is positioned at certain angles relative to the IR receiver. The app is the more reliable control method for detailed adjustments.
Bluetooth Connectivity
Bluetooth allows wireless audio streaming from phones, tablets, and laptops. The connection is stable within a typical room, and the system supports standard Bluetooth profiles for broad device compatibility.
There’s no Wi-Fi streaming or multi-room audio support, which is consistent with the price tier but worth knowing if you’re hoping for whole-home audio integration.
How Easy Is the TCL S55H to Set Up?
Setup takes most users under 15 minutes. The soundbar connects to a TV via HDMI ARC (the preferred method for full feature access) or optical audio.
The wireless subwoofer pairs automatically when powered on. Running the room calibration adds a few more minutes but is worth the time.
TCL TV owners get the tightest integration: the soundbar can appear in the TV’s audio settings menu, and volume control syncs automatically. With non-TCL TVs, HDMI ARC still works well for volume sync, but some advanced features may require manual configuration through the app.
Common setup mistakes to avoid:
-
Plugging into a standard HDMI port instead of the HDMI ARC port on the TV
-
Skipping room calibration and then wondering why the bass sounds off
-
Positioning the soundbar too close to a wall, which can cause reflections that muddy dialogue

Who Should Buy the TCL S55H?
The TCL S55H is the right choice for buyers who want a clear, immediate improvement over their TV’s built-in audio and have a budget of around $140.
Specifically, this soundbar makes sense if you:
-
Own a TCL TV and want a seamlessly integrated audio upgrade
-
Watch a lot of streaming content (Netflix, Disney+, Apple TV+) that uses Dolby Atmos or DTS:X
-
Want real bass from a wireless subwoofer without running speaker cables
-
Have a living room or bedroom up to roughly 400 square feet
-
Are new to external audio systems and want a simple, app-controlled setup
If you’re looking for a budget soundbar with a subwoofer and don’t want to spend more than $150, the S55H is one of the strongest options currently available at this price.
Who Should Skip the TCL S55H?
The S55H is not the right fit for every buyer. Skip it if:
-
You need true Dolby Atmos height channels: The virtual processing is no substitute for upward-firing drivers or ceiling speakers. If Atmos accuracy matters to you, explore options in our best soundbar for Dolby Atmos guide.
-
You want Wi-Fi streaming or multi-room audio: The S55H is Bluetooth-only for wireless audio.
-
You have a very large room: Rooms over 500 square feet may find the 220W system underwhelming at high volumes.
-
You’re a critical music listener: The bass-forward default tuning and 2.1 configuration aren’t ideal for audiophile music listening.
-
You need rock-solid remote reliability: If you rely heavily on a physical remote and don’t want to use a smartphone app, the reported remote inconsistencies are worth factoring in.
How to Get the Best Deal on the TCL S55H
The S55H is currently listed at $139 on Amazon, down from its $159.99 list price. A few tips for getting the best value:

Frequently Asked Questions
Does the TCL S55H work with non-TCL TVs?
Yes. The S55H connects via HDMI ARC or optical audio and works with most modern TVs. TCL TV owners get the most seamless integration, including automatic volume sync through the TV’s settings menu, but the soundbar functions normally with Samsung, LG, Sony, and other brands.
Is the Dolby Atmos on the S55H real or virtual?
It’s virtual. The S55H processes Dolby Atmos and DTS:X signals but does not have upward-firing drivers. The effect is a wider, more dimensional soundstage rather than true overhead audio separation. For most casual viewers, this is a meaningful improvement. For dedicated home theater setups, it’s a compromise.
Why does my TCL S55H volume keep jumping to 0% or 100%?
This is a known issue reported by some users. It’s typically caused by IR signal interference (another remote or device sending conflicting signals) or a firmware bug. Try updating the firmware via the TCL Home app, check for other IR-emitting devices nearby, and consider using the app for volume control rather than the physical remote.
TCL S55H Review: FAQs
How far can the wireless subwoofer be placed from the soundbar?
TCL doesn’t publish a specific maximum range, but in practice the wireless connection is stable up to roughly 30 feet in an open room. Walls and other obstructions can reduce effective range. For most living room setups, placement anywhere in the same room is reliable.
Does the TCL S55H support HDMI eARC?
The S55H supports HDMI ARC. Check your TV’s specifications to confirm whether it has an ARC or eARC port. ARC supports Dolby Atmos via a compressed format (Dolby Digital Plus), which is sufficient for streaming content. Full uncompressed Atmos from Blu-ray requires eARC, which the S55H may not fully support depending on the TV’s implementation.
Can I control the TCL S55H with a voice assistant?
The S55H does not have a built-in voice assistant. However, if you use an Alexa or Google Home device in your home, you may be able to control it indirectly through smart home routines if your TV supports voice control integration. For a soundbar with native Alexa support, see our Alexa-enabled soundbar guide.
Is the TCL S55H good for music?
It’s competent for casual music listening via Bluetooth. The wireless subwoofer adds depth to bass-heavy genres. The default EQ leans bass-forward, so jazz, classical, and acoustic listeners should adjust the EQ settings or run room calibration to get a more balanced sound. For dedicated music listening, a soundbar specifically tuned for music would serve better. See our best soundbar for music guide for alternatives.
Final Verdict
The TCL S55H delivers exactly what it promises: a meaningful audio upgrade over built-in TV speakers, real bass from a wireless subwoofer, and modern codec support, all for $139. The auto room calibration and app control add genuine utility that you don’t typically find at this price.
The volume control inconsistencies and remote reliability issues are real drawbacks that affect a portion of users.
They’re not universal, but they’re frequent enough to mention honestly. If you’re willing to use the app for detailed control and can tolerate occasional remote quirks, the overall value proposition is strong.
For TCL TV owners specifically, this is an easy recommendation. The integration is tight, the setup is fast, and the audio improvement is immediately obvious.
For owners of other TV brands, the S55H still performs well, though you’ll want to confirm HDMI ARC compatibility before purchasing.
At $139, the TCL S55H is one of the more complete budget soundbar packages available. It won’t satisfy audiophiles or buyers who need true Atmos height channels, but for everyday TV watching, streaming, and casual music listening in a standard-sized room, it gets the job done with room to spare.
