The TCL Pro Super Bass S55HK is a compact 2.1 soundbar with a wireless subwoofer, designed to give your TV a serious audio upgrade without a serious price tag. With 220W of total audio power, Dolby Atmos and DTS Virtual:X, it promises immersive sound that goes well beyond what most built‑in TV speakers can manage.
TCL has built a reputation for strong value in TVs and soundbars, and this model follows that formula: modern features such as HDMI eARC, Bluetooth 5.2 and auto room calibration are all on board, yet the price sits firmly in budget territory for a home cinema soundbar.
User feedback is positive, with an average rating of 4.2 out of 5 from a small but encouraging pool of reviews. That suggests most buyers are impressed with the performance and features for the money, with only a few minor niggles.
The TCL Pro Super Bass S55HK is ideal if you want a big step up from your TV’s speakers but you do not want to spend hundreds on a full surround system. The 2.1 setup with wireless subwoofer will comfortably fill a small to medium living room with fuller, more cinematic sound.
It suits budget‑conscious buyers who still care about modern features. You get Dolby Atmos and DTS Virtual:X for a more immersive soundstage, HDMI eARC for simple TV connection, and Bluetooth 5.2 for quick music streaming, all at a price that undercuts many well‑known rivals.
If you are a first‑time soundbar owner or upgrading from a very basic bar without a sub, this model hits a sweet spot. The auto room calibration helps dial in the sound without fuss, night mode keeps things neighbour‑friendly, and the equaliser and sound modes let you tweak audio without needing to be an expert.
It is less suited to very large rooms or home cinema enthusiasts chasing true surround with separate rear speakers. For most everyday TV, films and gaming in an average UK lounge, though, it is a strong, no‑nonsense choice.
The 220W of audio power, paired with a dedicated wireless subwoofer, delivers a much fuller and more impactful sound than any standard TV speakers, especially for action films and gaming.
Dolby Atmos and DTS Virtual:X support mean you get a convincing sense of height and surround from a simple 2.1 bar, adding drama to movie soundtracks and improving clarity around dialogue.
HDMI eARC and Bluetooth 5.2 make setup and everyday use straightforward. One HDMI cable can handle TV audio, while Bluetooth lets you stream music or podcasts from your phone in seconds.
Features like AI Sonic Auto Room Calibration, night mode and preset sound modes (Movie, Music, TV) give you useful control over how it sounds, without overwhelming you with complex menus.
The compact 81 cm width and wall‑mounting option make it easy to fit beneath most TVs or on the wall, even in tighter living spaces.
There is no analogue aux‑in and no Wi‑Fi, so you are limited to HDMI, optical and Bluetooth – fine for most TVs, but less flexible if you like to plug in older kit or stream over a home network.
Despite Atmos and DTS Virtual:X support, this is still a 2.1‑channel system with no rear speakers, so you should not expect the same enveloping surround sound as a full multi‑speaker setup.
The soundbar offers useful EQ and modes, but there is no mention of a dedicated app with detailed tuning or multiroom features, which some more premium rivals now include.
The 4.2 user rating is solid rather than outstanding, and with only a handful of reviews so far, long‑term reliability and quirks are a little less proven than on long‑established models.
Living with the TCL Pro Super Bass S55HK should be refreshingly simple. HDMI eARC support means you can usually connect a single cable from the bar to your TV, then control the volume using your existing TV remote. If your TV does not support eARC, you can still use standard HDMI ARC or the optical input.
The wireless subwoofer is a big win for keeping cable clutter low. You can place it off to the side of your TV unit or tuck it near a wall socket, letting you fine‑tune bass presence without running a long cable across the room.
At just 6.2 cm tall and 81 cm wide, the bar is slim enough to sit in front of most TVs without blocking the screen, and wall mounting hardware is included if you prefer a cleaner, floating look. The LED display and remote make it easy to see which source or mode you are in, while auto power off helps keep energy use down.
Night mode is particularly useful in flats or terraced homes, reining in the bass and smoothing loud effects so you can watch films late without constantly riding the volume. The equaliser and three sound modes let you adjust the sound for sport, drama or music quickly, so you can largely set‑and‑forget after initial setup.
For a compact 2.1 system, the TCL Pro Super Bass S55HK packs a respectable 220W of total audio power. Paired with the active wireless subwoofer, it delivers strong low‑end presence that brings explosions, soundtracks and game effects to life in a way a TV alone simply cannot.
Dolby Atmos support and DTS Virtual:X processing work to create a more spacious and three‑dimensional soundfield from the bar’s two speakers. While you do not get physical up‑firing or rear channels, there is still a tangible improvement in immersion, particularly with Atmos‑enabled streaming services and Blu‑rays.
AI Sonic Auto Room Calibration is a standout at this price, analysing your room and adjusting the sound profile to suit. That means clearer dialogue and more balanced bass without having to dive into manual EQ settings, which helps if your sofa is not perfectly placed or your room is a tricky shape.
Connectivity covers the essentials well. HDMI 2.1 with eARC and ARC support is the main route for TV sound, and there is an optical digital input for older sets. Two USB ports plus USB playback for popular formats (FLAC, MP3, WAV, WMA) turn the bar into a simple media player, and Bluetooth 5.2 ensures stable wireless streaming with low drop‑outs.
Other thoughtful touches include smartphone control support, auto power off to cut standby use to around 0.5W, and a two‑year manufacturer warranty, which is reassuring at this end of the market. Together, these features make the S55HK feel more rounded and future‑proof than many similarly priced basic bars.
At around £99, the TCL Pro Super Bass S55HK sits firmly in the budget end of the soundbar market, yet the feature list reads more like a mid‑range model. Getting a 2.1 system with a wireless subwoofer, Atmos and DTS Virtual:X, HDMI eARC, auto room calibration and Bluetooth 5.2 at this price is impressive.
The 4.2 out of 5 user score supports the sense that you are getting a lot for your money. Most owners appear to be satisfied with the performance jump over TV speakers and the ease of setup, which is crucial at this price point where buyers are often upgrading for the first time.
If you are chasing absolute top‑tier sound or true surround with rear speakers, spending more will naturally bring gains. But as a cost‑effective way to make films, sport and everyday TV sound bigger and clearer, the S55HK offers very strong value. You are paying budget money for a genuinely modern spec sheet.
The TCL Pro Super Bass S55HK is a very capable budget soundbar that delivers on its promise of bigger, more immersive sound without complicating your setup or emptying your wallet. The combination of 220W power, a punchy wireless sub and virtual surround processing makes it a clear upgrade over TV speakers for most living rooms.
It is particularly appealing if you want Atmos and DTS Virtual:X effects, simple HDMI eARC connectivity and handy touches like auto room calibration and night mode, but do not need physical rear speakers or Wi‑Fi streaming. For films, sport and gaming in small to medium rooms, it strikes a smart balance of features and performance.
Those who prioritise audiophile‑grade sound, full 5.1 systems or app‑driven multiroom will want to look higher up the price ladder. For everyone else looking for a straightforward, modern and affordable way to boost TV and music sound, the S55HK is an easy model to recommend.
