Sharp has been making significant strides in the UK audio market with its Q series soundbars, and the HT-SBW53121 represents an impressive entry in the mid-range segment.
This 3.1.2 channel soundbar, when paired with the optional HT-SPR52021 wireless rear speakers, creates an impressive 5.1.4 surround sound system that aims to bring cinema-quality audio to your living room.
The Sharp Q series marks the company’s return to form in the audio space, with products that prioritise sound quality over unnecessary smart features. This approach becomes particularly evident with the HT-SBW53121, which skips Wi-Fi connectivity and streaming apps in favour of focusing on what matters most: delivering great audio performance at a reasonable price.
What sets this system apart is its collaboration with Devialet, the French audio specialist renowned for its premium speakers and acoustic engineering expertise. This partnership brings professional tuning to a consumer-friendly price point, promising to elevate the audio experience beyond what you’d typically expect from a soundbar in this category.

Unboxing / Design / Build Quality

The Sharp HT-SBW53121 arrives in a sizeable box, reflecting the soundbar’s generous proportions and the inclusion of a decent-sized wireless subwoofer. The soundbar itself is finished in matte grey plastic, with a simple, functional design that should suit most living rooms. The front grille is metal, providing some reassurance in terms of durability, while the rest of the chassis is plastic. The unit feels solid, although it lacks the premium finish seen in some higher-priced competitors.


The rear speakers are relatively compact and unobtrusive. They share the same understated design language as the soundbar, with a practical build that prioritises function over form. The subwoofer is large and boxy, with a downward-firing driver and a ported enclosure. While the materials are not luxurious, the overall construction is sturdy and should withstand regular use.


Set Up
Setting up the soundbar is a straightforward process, largely due to the fact that it lacks any network connectivity and smart features.
You plug the cables into the right places, and that’s about it.
For the surround sound speakers, you need to pair them with the soundbar. To do this you need to:
- Ensure that all the cables are securely connected and the soundbar is in STANDBY.
- Press and hold the PAIR button on the rear of the speaker for 3 seconds. The speaker will enter pairing mode, and the PAIR indicator will flash quickly.
- Press the power button on the soundbar or on the remote control to switch the soundbar on.
- Press the MENU button on the remote control, then use the directional control on the remote control to highlight <WLPAIR>. Press the play/pause button and wait for 5 seconds.
- When the speaker is paired with the main unit, the PAIR Indicator will be solid and the soundbar will display <PAIRED>.
- If the PAIR indicator blinks, the wireless connection has failed. The soundbar will display <SPK NC>. Unplug the power cable from the speaker and then reconnect the power cable after 4 minutes. Repeat steps 1 to 4.
Features and Connectivity
The HT-SBW53121 offers a broad range of connectivity options, including:
- 2 x HDMI inputs (plus HDMI-eARC output)
- Digital optical input
- 3.5mm aux-in
- USB playback
- Bluetooth 5.3 (SBC and AAC+ codecs)
- HDMI-CEC for TV remote control
The HDMI-eARC functionality is particularly beneficial for those using newer TVs, as it supports higher-quality audio formats and allows for synchronised power and volume control with the TV remote.
Audio decoding support is generous, including Dolby Atmos, Dolby TrueHD, Dolby Digital Plus, DTS:X, DTS-HD, and DTS 5.1. For USB playback, the soundbar supports a broad range of formats: MP3, OGG, WAV, FLAC, AAC+, and ALAC.
Users can adjust individual bass and treble levels with the remote, and the equaliser presets cover a wide range of scenarios, including Movie, Music, Sport, Game, Voice, Night, and a Custom mode.
The remote control is functional, with direct access to sound modes, input selection, and individual adjustment for bass and treble. The on-unit controls are basic but sufficient for day-to-day use. The LED display provides clear feedback but is not as discreet as some OLED alternatives.
Audio Performance

Sound Quality
The HT-SBW53121 performs well and delivers a full-bodied sound with clear dialogue, punchy bass, and a convincing sense of space, especially when paired with the rear speakers.
The 3.1.2 surround sound has a left, right, centre (3), a subwoofer (1) and two height channels (2).
The dedicated centre channel ensures that voices remain intelligible even during busy action scenes, and the up-firing drivers add height to the soundstage when playing Dolby Atmos or DTS:X content.
The up-firing Atmos speakers are something you don’t see often at this price point.
The subwoofer provides ample low-end presence, enhancing explosions and music without overwhelming the midrange. Bass is tight rather than boomy, and while it may lack the sheer depth of larger, more expensive subs, it is well integrated with the soundbar.
The rear speakers make a noticeable difference to immersion, particularly with surround-encoded material. Effects move convincingly around the room, and the up-firing drivers contribute to a sense of height, though the effect is more subtle than in systems with side-firing or ceiling speakers. The system performs well with both films and music, although stereo music playback is less engaging than multi-channel content.
Sound Modes and Customisation
The soundbar offers several EQ presets: Movie, Music, Voice, Sport, Game, Night, Custom, and Off. Each mode subtly tweaks the frequency response to suit different content. The Movie mode enhances surround effects and bass, while Voice mode brings dialogue to the forefront. The Night mode compresses dynamics for late-night viewing.
There is also manual adjustment for bass and treble, allowing users to tailor the sound to their preference or room acoustics. The lack of automatic room calibration is a limitation, but manual adjustment is simple enough for most users.
Dolby Atmos and DTS:X
Support for Dolby Atmos and DTS:X is a key selling point. The soundbar’s up-firing drivers create a sense of verticality, with effects such as rain or helicopters appearing to come from above. While the effect is not as pronounced as with ceiling speakers, it adds an extra dimension to compatible content.
The system handles object-based audio well, with smooth transitions between channels and a coherent soundstage. However, the overall effect is dependent on room shape and ceiling height, and some users may find the height channels less effective in larger or irregular spaces.
Music Playback
Music playback is competent, with a balanced sound that avoids harshness at high volumes. The system supports a range of audio formats via USB, and Bluetooth streaming is stable and straightforward. While the soundbar is optimised for film and TV, it performs respectably with music, offering clear vocals and sufficient bass for most genres.

Overall
The Sharp Q HT-SBW53121 soundbar, paired with the HT-SPR52021 rear speakers, offers a convincing surround sound experience at a competitive price.
I think the lack of smart features has allowed Sharp to focus on the important things you need from a soundbar, the overall audio quality.
Strong points include the inclusion of a subwoofer, eArc, and the upwards-firing speakers for Dolby Atmos and DTS:X content. There are not many other systems that offer this level of audio features at this price point.
For users seeking a no-nonsense home cinema upgrade with true 5.1.4 channel sound at a sensible price, the Sharp HT-SBW53121 and HT-SPR52021 combination is an excellent choice. It is not without its compromises, but it delivers a level of performance that will satisfy most film and TV enthusiasts looking to step up from their TV’s built-in speakers.
Sharp Q HT-SBW53121 Soundbar + HT-SPR52021 Rear Speakers Review
Summary
The Sharp Q HT-SBW53121 Soundbar, when paired with the optional HT-SPR52021 rear speakers, delivers a full-fledged 5.1.4 surround sound experience that stands out in the sub-£600 bracket. It avoids the distractions of built-in smart features and streaming services, instead concentrating on robust audio performance, broad format support, and a straightforward user experience. Its collaboration with Devialet enhances its audio credentials and sets it apart from similarly priced alternatives.
The sound profile is well-balanced with a clear centre channel for dialogue, decent bass response from the subwoofer, and immersive surround effects thanks to the rear and up-firing speakers. While the system lacks automatic room calibration and some premium finishes, these compromises feel acceptable given its performance and pricing.
This soundbar system is best suited to users looking to improve their home cinema setup without diving into the complexity or cost of a full AV receiver and speaker system.
