Samsung HW-QS90H Review – Trusted Reviews

Introduction

While most soundbars technically support wall mounting, even sometimes including wall brackets in their boxes, that support is typically compromised in both design and sound quality terms.

Soundbars designed to lie flat on a table, for instance, like the vast majority are, usually jut out awkwardly from walls, while their sound can be affected by how high they’re sat when wall hung versus a typical desktop placement.

Cue Samsung’s HW-QS90H: A soundbar that can actually reconfigure its speakers deliver which channels of sound depending on whether its sitting flat on a table or hanging flat against a wall.

This isn’t Samsung’s first stab at such a ‘convertible’ soundbar; that honour belongs to the 2025-launched HW-QS700F. The QS90H is Samsung’s first convertible soundbar to offer a 7.1.2 channel count – while simultaneously daring to ship without the external subwoofer the QS700F provided.

Can a one-bar sound solution really deliver so many unusual and premium features without its sound quality suffering?

Design

• Convertible design speaker system
• Enjoyably industrial hard plastic finish
• 13 driver 10-channel design

The HW-QS90H closely tracks Samsung’s other recent premium soundbar designs. So there’s the same hard black plastic finish, the same engaging mix of a striped effect on its top edge and circular perforation effect on its sides, and the same crisp, rectangular shape – only without the double-angled left and right ends you get with Samsung’s flagship soundbar designs.

The QS90H’s measurements of 1245(w) x 68.8(h) x 125(d)mm are fairly substantial by most one-bar solution standards. The fact that it rests on its flat bottom edge regardless of whether it’s lying down or hanging on a wall, though, gives it a relatively minimal profile.

You don’t have to accommodate an external subwoofer, either, and actually, once you start to listen to it its size suddenly starts to feel pretty small in the context of the epic soundstage it can create.

Looking at the QS90H in its table-top configuration, two speakers set at different angles in its left and right edges enable the soundbar to deliver separate side left/right and front side left/right channels, while the long straight front edge holds the more typical left and right channels, plus a centre channel speaker that unusually sits right at the top of the front edge.

There are also two drivers in the top edge (again, remember, we’re talking about the tabletop profile here) for delivering height/overhead effects.

To compensate for not having an external subwoofer, the QS90H also somehow finds space for four bass woofers within its compact design.

It’s all change if you want to wall hang the soundbar. To adapt it for wall hanging you have to stand the QS90H on its edge and then turn it through 180 degrees so that the control buttons are sitting along what is now the soundbar’s bottom edge. The flat edge that was the underside of the soundbar in its table top stance becomes the rear edge that lies against the wall, meaning the soundbar only sticks out 68.8mm rather than the 125mm if it was fastened to a wall in the same orientation it uses on a desktop.

The speakers that were the front left and right speakers become the two up-firing speakers, while the two speakers that were the up-firers in the QS90H’s desktop setup become the front left and right. The centre channel speaker’s unusual high position in a tabletop set up now makes sense, as it means it can continue as the centre speaker in the vertical orientation too.

The ability of the QS90H to deliver a slender profile in both its setup positions puts it in very rarified company indeed. There are a few dedicated wall hanging soundbars out there, but soundbars that can truly adopt their sound and design for both flat or vertical orientations are incredibly few and far between.

The on-bar controls I mentioned earlier offer voice control mic on/off buttons, as well as simple up and down volume adjustments. The only other disruption to the sleek black finish comes from a little row of LEDs designed to help you figure out roughly what volume you’ve selected and which input you’re using. These are a poor second, though, to the full LED display you get on Samsung’s HW-Q990H.

The HW-QS90H’s connections comprise a one in, one out HDMI pass-through, eARC support on the HDMI output, an optical digital audio input, and the now inevitable Bluetooth and Wi-Fi support.

Features

• Dolby Atmos and DTS:X playback
• 7.1.2 channel count, plus optional extra speaker support

I’ve pretty comprehensively covered the QS90H’s most unique feature: Its support for flat-profile desktop or wall-hanging placement. There’s plenty more to get our teeth into besides.

Starting with the fact that it uses its 13 built-in drivers to deliver an impressive 7.1.2 channels of sound. This is an impressive channel count for a single bar soundbar, delivering front left, front right, front centre, front left side, front right side, left side, right side and two up-firing channels, with a quartet of woofers squeezed in to deliver low frequency sounds. Which drivers deliver which channels is, of course, fluid, based on the soundbar’s orientation.

It’s worth noting at this point that a built-in gyroscope automatically informs the HW-QS90H whether it’s been used in its horizontal or vertical configuration; you don’t need to tell it manually.

Inevitably as a single-bar solution, the QS90H doesn’t deliver any surround sound effects. You can add extra speakers to it, though, using either Samsung’s SWA-9500S optional wireless rear speaker package, or up to four of Samsung’s startlingly powerful new Music Studio speakers.

As with all recent Samsung soundbars, the QS90H can also join forces with (rather than just replacing) the speakers in pretty much all of Samsung’s recent TVs thanks to Samsung’s Q Symphony feature, creating a bigger and more detailed centre channel sound.

Q Symphony can work via HDMI eARC or wirelessly, with further wireless functionality coming in the shape of wireless Dolby Atmos reception from suitably capable Samsung TVs.

The Dolby Atmos support is joined by support for both the DTS:X format and the Eclipsa Audio open-source format developed by Samsung and Google.

You can get any sound format, even stereo music, to take advantage of the HW-QS90H’s full channel count if you choose a provided Surround Sound audio preset. Purists can rest assured that the soundbar’s Standard preset will play any format in its native form – including simple two-channel stereo.

The HW-QS90H also leans in to Samsung’s love of AI with an Adaptive mode, which analyses the incoming sound so that it can recognise the type of content and optimise the way the soundbar presents the audio accordingly. AI is in play with a dialogue enhancement feature that can isolate vocal tracks and give them more emphasis in response to detected increases in ambient noise levels in your room.

The QS90H’s Wi-Fi capabilities include integrated support for AirPlay, Google Cast, Spotify Connect and Tidal Connect, and it’s also Roon Ready. Accessing all these sound systems is made easy if you’re using the Samsung SmartThings or new Samsung Sound apps to control the soundbar rather than the sleek but basic provided remote control. The same apps also streamline initial set up, helping you get your soundbar online and update its software with minimal fuss.

The apps provides exclusive access to a couple of handy set up aids: An adaptive bass feature that automatically monitors the sound for potential bass-related distortions, correcting the sound profile to correct for this if required, and a Space Fit system that continually optimises the soundbar’s presentation to your room conditions.

The QS90H’s HDMI pass-through supports HDR10+ and Dolby Vision HDR formats, as well as the more basic HDR10 and HLG formats. The HDMI pass-through system does also deliver arguably the only real feature disappointment with the QS90H, though, as it turns out that it doesn’t join Samsung’s HW-Q990H flagship soundbar’s loop through in supporting 4K/120Hz signals.

You can only get 120Hz frame rates through the soundbar if you settle for a 1440p resolution and don’t mind losing high dynamic range support. If you want 4K and HDR, you’ll have to set your game source to 4K/60Hz. The soundbar does support pass-through of variable refresh rates with both 60 and 120Hz signals, and carries a Game Pro sound setting that emphasises channel steering to make gaming worlds feel more intense and help you detect where enemies might be attacking from.

Sound Quality

• Equally excellent music and movie playback
• Outstanding sound in both horizontal and vertical configurations
• So good that it will tempt you to add rear speakers

Before getting into the specific ins and outs of how well the HW-QS90H delivers on its headline multi-placement ‘convertible’ feature, let’s get some general performance features out of the way.

Starting with the fact that it copes incredibly well without the external subwoofer shipped with 2025’s QS700F convertible soundbar debutante. The bass woofers crammed into the QS90H’s single-bar form sound anything but crammed in, rolling out some of the very deepest frequencies I’ve ever heard from an all-in-one soundbar option without the bass bottoming out, lagging behind the rest of the mix or succumbing to chuffing/crackling distortions or drop outs.

Unless you increase the soundbar’s volumes to levels far beyond anything the average human ear will be able to cope with.

The QS90H’s bass spreads far and wide so smoothly, that it delivers exactly the sort of non-directional presence you want from any good movie bass system. It does all this without the bass overwhelming the rest of a movie mix.

In fact, the QS90H maintains levels of detail, power, effects placement and channel steering that precious few other single-bar soundbars can even get close to – exactly as I’ve come to expect with Samsung’s premium soundbars. The bass is just a beautifully weighted but also surprisingly nimble counterpoint to everything else that’s going on rather than any sort of ‘dead weight’ dragging the sound down.

Trebles never sound harsh or warbly either, and the speakers are sensitive enough to not only pick every sound detail out, no matter how subtle, but also present each of those sound effects with the correct level of prominence. There are no moments where subtle background ambient effects surge into the foreground, or birds tweeting suddenly sound on a par with key dialogue.

Dialogue, now I’ve mentioned it, is always clear and clean, regardless of how deep or shrill the talker’s voice might be, and the soundbar gives vocals a nice vertical lift so that they sound like they’re coming from the onscreen action rather than the soundbar below the screen.

There’s even an ‘Elevate’ option that does a good job of lifting the vertical position of dialogue higher should you be using the soundbar with a truly huge screen, or you’ve got a bigger vertical gap than usual between your screen and soundbar below. Which can happen with wall hung setups, or if you’ve got the soundbar sat on a sideboard with a wall mounted screen above it.

The channel steering that’s been such a consistent Samsung soundbar strength for years now is exceptionally well deliver by the HW-QS90H, creating a truly three-dimensional and immersive sound space between you and your screen. You truly feel the impact of the 7.1.2 channel count in the dynamism, fullness and expansive scale of the sound the QS90H creates.

So good is the QS90H’s staging, in fact, that it had me yearning for some surround sound speakers, so that I could find myself right at the heart of the audio action. The idea that a one-bar soundbar might be good enough to seriously tempt you to splash out on further speakers to create a true surround sound system is hardly a weakness!

Though there could be an argument here for stepping up to Samsung’s full surround sound HW-Q990H soundbar package instead.

All of the strengths explained so far are underpinned by phenomenal amounts of power by mid-range soundbar standards, and are achieved regardless of whether the QS90H is used in a vertical or horizontal stance.

Some differences in the sound do become apparent as you switch the HW-QS90H from a horizontal to a wall mounted position. On the downside, the wall-mounted sound doesn’t push forward with quite as much force. This means the wall-mounted sound stage feels a bit less three-dimensional, and hard impact sounds – while still clean and crisp – lack a little of the visceral potency you get in the QS90H’s horizontal stance.

Bass is a little less potent when the QS90H is wall mounted, too – though it’s still plenty powerful enough to leave the bass from many rival soundbars sounding either coarse or thin.

Height effects are delivered with actually slightly more clarity and emphasis in the QS90H’s wall mount mode than you get from its tabletop set up, though.

Dialogue sounds slightly more rounded and smooth from a wall-mounted QS90H, too, and the sound impressively radiates down as well as up from the soundbar’s relatively elevated wall-mount position, avoiding that ‘the only way is up’ effect you often get if you wall mount regular soundbars at higher positions than they’re truly designed to suit.

The HW-QS90H isn’t just a beast of a soundbar with film soundtracks. In both of its placement configurations it also handles stereo music remarkably well, subtly shifting to nimbler, less bombastic bass handling and beautifully recalibrating its multi-channel scale down to simple two-channel stereo without the results sounding crowded or over-aggressive.

Stereo separation is bold but not forensic or forced, and vocals of every type are beautifully located at the heart of the mix without ever becoming either too shrill or too soupy.

There’s a musicality here, in fact, that you’d normally only expect to hear from soundbars from established heritage hi-fi brands.

There are a couple of issues to mention beyond the small differences between the vertical and horizontal profiles covered earlier. One is that just occasionally, especially in the tabletop stance, voices can sound a little too prominent and bright. Such moments truly are rare, and even at their worst voices don’t actually sound brittle or completely lose their context.

Perhaps related to this, while ambient effects never gain too much weight in the mix, occasionally relatively high-pitched background sounds can – again only very occasionally – sound a touch sibilant.

Finally, again incredibly rarely, particularly violent and deep extended bass sounds can cause the QS90H’s bass speakers to start sounding just a little rough around the edges. Though they don’t succumb to outright distortion and breakdown.

Should you buy it?
