Sony ULT TOWER 7 Trådlös Bluetooth högtalare, svart

[This review was collected as part of a promotion.] I already own and use a Sony ULT Field 7, so I was keen to know just how far Sony could push the portable power boundaries.

TLDR : the ULT Tower 7 is party powerful, with crisp sound and an unarguably ULTimate bass.

Now the long parts.

Delivery and Basics

The delivery guy said “I don’t know what it is, but it’s heavy.” He’s not wrong. Shipping info said 26 kilos, the specs sheet says just under 23 kilos. Not so much of a consideration when unboxed and able to use the multiple hand holds and wheels, but in the box you may need a second person. The box itself is typically Sony robust and protective, with cut outs for carrying. Note that when you open the box it does have a leaflet indicating to tip the box up to remove it, and not to lift the speaker out of the box. Following this process works a treat. Contents include power cables for EU and U.K. , paper instructions and a QR and quick start. I guess that you could use this without the Sony Sound Connect app but you’ll be missing out on some easy functionality and additional support. Download the app if you haven’t got it.

Appearance and construction

It’s big. This is no bookshelf or smart speaker. It makes a statement in any room. There are substantial handles on the top of the unit; a pull handle on the top rear and wheels on the base. The speaker also has isolation rubberised feet allowing for it to be placed upright or lying lengthwise. It’s surprisingly portable using the wheels but I’d like a slightly larger or accessible handle to pull it for my hand size. On delivery there’s a card with demo mode instructions in this handle. I tried to remove the card and adhesive at the same time but tore the card and was prepared for spending too long removing glue residue. Not so! It was a single simple roll up strip that came away cleanly. A small point but it’s an attention to detail that makes the difference. Connectivity for USB A , USB C, line in, mic is under the water resistant flap at the rear (IPX4 when closed). You can charge devices from the USB’s.

Set Up

Once unwrapped of course I just pressed the power button on the top. Pairing was automatically underway and linked to my phone almost instantly.

I restarted my Sony Connect app and the speaker and it’s functionality were all displayed.

The app has a pleasing rotating graphic of the speaker and you can personalise the shortcuts on the front page. There’s too much to include in an already long review, but you can change the lighting and add a variety of effects even if not using a mic/karaoke.

Usefully there’s a “stamina” option for extending battery life. Specs say 30hrs of life, which is long enough for most parties although that will be lower depending on if you push it loud and hard and if you select the Battery Care option to help overall battery life. Regardless, it should match your party and a 10 minute plug in gives about 3 hours of use, so there’s some good battery smarts there.

In Use

Sony TV’s are renowned for their reference status, setting and adopting industry standards for use in the home. For this ULT range they have worked with DJ’s and creators and the result is a truly impressive sound. The basic raw power of 420w tells part of the story but how that’s delivered is more important. The bass rocks the room. Effortlessly change the intensity using the combined volume and ULT button on the front. It never feels like it’s struggling or that it’s overwhelming everything else.

Then there’s the sound stage, the combination of ULT woofer with a pair of mids and 2 pairs or tweeters (1 pair front 1 pair rear) it lays everything out giving an impression of a working stereo pair from a single unit.

As for volume, I understand that speakers should be run in so I’ve not tried to shake the foundations but I can easily hear the this all over the house on a low setting. On a moderate setting you feel the music in your body. The recent weather has limited outdoor use, but I suspect you’d need to invite neighbours from streets away if crank it up and you use it in your garden for a party.

In short it sounds superb playing all types of music and if you need bass, it’ll more than match your mood.

There’s also an impressively bright and colourful light display in the front edges of the grill. You can use these to help set the mood and they can be personalised in the app.

Final thoughts

This is a substantial bit of kit so you’ll need to commit to the space. If you want something more manageable there’s a smaller version which will doubtless be equally as impressive.

However once bought and listened to you’ll be glad that you took the plunge. Impressive in sound, bass, lighting and build quality it’s a superb self contained speaker for playing all kinds of music, from all kinds of sources indoors and outdoors. I was surprised at the list price when I’ve bought smart speakers costing nearly as much which sound frankly awful in comparison and never get used as anything smart. If you’re a PT that needs a portable sound system for larger venues then this should be on your list.

This is serious kit for accessible money. Whatever music you listen to or create, this has the music power and bass to get the party started and the battery power to keep it going

[This review was collected as part of a promotion.] The Sony ULT TOWER 7 is a fun, easy-to-use speaker that really is a case of pick it up, connect and play. The Sony Sound Connect app allows for quick, seamless pairing with the speaker and offers a wide range of control settings, from sound customisation and lighting effects to a quirky karaoke soundboard.

Design and Features

The ULT TOWER 7 features four quick-access buttons. The three on top are self-explanatory: power, Bluetooth connectivity, and play/pause. The fourth, located on the front and marked ULT, provides access to the volume controls and three quick sound modes, allowing you to switch between presets or create your own balanced sound profile.

Sony has also considered portability, equipping the speaker with four carrying handles and two wheels at the rear. However, I would have liked to see a handle at the top rear, making it easier to tilt and pull the speaker along when moving it around.

The front-facing lights are a fun addition. They aren't essential, but they certainly add to the atmosphere. As you'd expect, there's a range of colours and lighting modes to choose from, allowing you to tailor the look to your surroundings or mood.

Sound Quality

It's fair to say that it's difficult to justify running this speaker at maximum volume. At around halfway, there's already more than enough output for most situations. That said, even when pushing it to the max during my testing, I experienced no noticeable distortion or compromise in sound quality.

It's worth noting that I had the battery-use setting configured to prioritise sound performance. I haven't tested extensively with battery life prioritised, so I can't comment on how much that changes the experience. With my settings, though, I have no complaints.

Now, let's talk bass. I found myself gravitating towards ULT Sound Mode 2, and the bass output is absolutely insane! If you want to feel your music, this speaker certainly delivers. However, if you don't want the entire house vibrating, Live Sound mode offers a more balanced presentation, reducing the emphasis on bass while still providing plenty of volume.

Whether you're after bass-heavy music to get the party going or something more balanced for everyday listening, there's enough flexibility here to suit different situations.

Battery Life

For such a large speaker with this level of output, a claimed battery life of up to 30 hours is impressive (according to the box).

In my own use, the speaker has mostly been playing background music while I'm cleaning or gaming. Even when it's running for several hours at a time, it comfortably keeps the music going without me worrying about charging it or needing to plug it in.

Of course, actual battery life will depend on volume, lighting and sound settings, but for my everyday use, it has been more than sufficient.

Final Thoughts

I'm genuinely blown away by this piece of hardware. The Sony ULT TOWER 7 is powerful, enjoyable to use and, in my opinion, very fairly priced for what you get.

There are additional features and connections that I personally might not benefit from, but they're welcome additions that give the speaker extra versatility and value. For anyone working with music professionally, I'll include a photo of the input and output panel on the rear so you can see what's available.

Ultimately, if you love your music and want something capable of filling a room with powerful sound, whether that's at home, at a house party or in your local pub, the Sony ULT TOWER 7 is absolutely worth considering for your shortlist.

[This review was collected as part of a promotion.] Introduction

I have been testing the Sony ULT Tower 7 both indoors and outdoors, using a variety of music from my own collection and a range of different audio sources. My aim was to assess not only its performance as a high-power party speaker, but also how versatile it is as an everyday music system.

My testing has included music from the 1960s through to the present day, covering rock and roll, rock, heavy metal and other genres. I have also tested Bluetooth playback using a Samsung Galaxy S25 Ultra, Sony Walkman NW-A45, Samsung Galaxy Book Flex Laptop, USB playback from a music-filled USB A drive, and analogue playback from my Technics record player connected through the Line 1 input.

This range of sources gave me the opportunity to assess how the ULT Tower 7 performs with both modern digital sources and traditional analogue music.

Build Quality and Portability

The build quality of the ULT Tower 7 impressed me. Despite its size, it is relatively easy to handle while still feeling solid and well-constructed, with the main controls on the top for ease of access and the connections on the back behind a substantial waterproof cover.

Moving the speaker using the integrated rollers/casters was straightforward, making it easy to reposition around the house or move it outside into the garden. Lifting it using the side handles was also manageable.

There is one area where I think Sony could improve the design. For a taller person, using the grab handle to pull the speaker over a longer distance requires a slight crouching position. A short telescopic handle, similar to the handle on a suitcase, could make longer journeys more comfortable.

This would, in my opinion, be a useful design improvement while retaining the current portability of the speaker.

Setting Up and Connecting the Speaker

Initial connection to the Sony Sound Connect app was smooth and easy to follow. Once connected, the app provided convenient access to a range of the speaker's functions.

I used my Samsung Galaxy S25 Ultra, Sony Walkman NW-A45 and Samsung Galaxy Book Flex Laptop as Bluetooth sources, all playing music from my own collection. I also tested USB playback using a USB A drive containing music.

For me, one of the more interesting tests was connecting my Technics record player to the ULT Tower 7 through the Line 1 input. This demonstrated that the speaker is not restricted to Bluetooth or other modern digital sources.

Digital and Analogue Listening

The difference between the digital and analogue sources was particularly interesting.

When listening through the Technics turntable, I found the sound noticeably crisper and more distinctive than when using the Galaxy S25 Ultra or Walkman NW-A45. The analogue presentation had a different character in my view, with the interaction between the stylus and the vinyl groove producing what I perceived as greater depth and texture in the music. I believe this was partly due to the way the Tower 7 reproduced the characteristics of the analogue source.

I particularly noticed this in the tonal qualities and pitch of instruments and vocals. The vinyl playback gave the music a more natural and engaging character.

This was an important part of my testing because the ULT Tower 7 is primarily presented as a powerful party speaker, yet its Line 1 input also makes it sufficiently versatile for people who enjoy a traditional analogue music source.

ULT Sound Modes

The different ULT settings produced a noticeable change in the way the music was presented.

With the standard ULT setting, vocals remained clear and were more easily heard above the accompanying music. I found this particularly effective with vocal-led tracks where the singer is an important part of the recording.

Switching to the deeper-bass ULT setting changed the character of the music considerably. The increased bass gave the music a greater sense of presence, with the sound moving from what I perceived as being more in the background to becoming more immersive and seemingly surrounding me.

There was, however, a slight reduction in vocal prominence with the deeper-bass setting.

For bass-heavy music, and tracks where overall impact and atmosphere are more important than vocal clarity, I found the deeper-bass setting particularly effective. For vocal-led music, I preferred the standard ULT setting. There are 4 settings available in the sound effect section in the app, they are Flat, ULT 1, ULT 2 and live. Each is customisable in the app with its own Equaliser. I found using Flat and Live retained the music's original sound quality. All were tested at the aps neutral/0 range with no adjustment to the Equaliser. This function will allow users to adapt their music's sound to their own preference from a good, initial pre-set level.

Music Quality and High-Volume Performance

I tested the ULT Tower 7 with music from a wide range of genres and eras, including recordings from the 1960s through to the 1980s, as well as rock and roll, rock and heavy metal.

With the 1960s–80s recordings I tested, the sound quality remained good at low and medium volume levels. When pushing the volume towards the very high levels, I occasionally noticed a small amount of distortion, particularly with recordings featuring synthesised sounds and some of the production characteristics associated with music from that period.

Heavy metal retained its characteristic sound even at high volume, while rock and rock and roll also maintained good clarity and musical character.

Importantly, the slight distortion I experienced only became apparent when the volume was set very high. At normal listening levels, and even at fairly high volumes, I found the overall sound quality remained clear and enjoyable.

Indoor and Outdoor Performance

I tested the ULT Tower 7 both indoors and outdoors, including extended listening in the garden.

Indoors, the surrounding walls and other reflective surfaces contributed to the immersive effect of the sound. When I moved the speaker outside, that impression of being completely surrounded by the music was slightly reduced.

This was not a significant loss of sound quality, but rather the natural difference between an enclosed room and an open outdoor environment, where there are fewer surfaces for the sound to reflect from.

What impressed me was the consistency of the sound as I moved around the garden. The audio remained clear when moving around the listening area and when moving further away from the speaker.

I could also maintain control of the speaker through the Sony Sound Connect app while moving around the garden, making it easy to adjust settings without having to return to the speaker. This was also true indoors as I was able to control the Tower 7 from different rooms both upstairs and downstairs.

Sony Sound Connect App

The Sony Sound Connect app was straightforward to connect and easy to follow.

I particularly liked being able to adjust the EQ settings and control the lighting from the app. The lighting controls allow the colour, mode and rate to be adjusted, while the ability to synchronise the lighting with the music adds another dimension to the speaker when used for parties or outdoor entertainment.

The app also allowed me to connect the ULT Tower 7 with my devices and retain those devices for later connection once paired. This made switching between devices quick and easy once the connection had been established with the app.

Lighting

The lighting functions are easy to control through the app, and I found the different colour, mode and rate settings simple to use.

One limitation I noticed was the lack of a dedicated dimming control. While the lighting can be changed or switched off, I would have liked the ability to reduce the brightness to a level somewhere between full illumination and off.

Sony's instructions acknowledge that the lighting can appear bright or glaring and recommend increasing the room lighting or switching the speaker lighting off.

In my view, incorporating a brightness/dimming control into the app would be a useful future improvement. It would allow users to retain the lighting effect while reducing its intensity to suit the environment.

USB A Playback

I tested USB A playback using a USB A drive containing music from my own collection.

Having tested Bluetooth through both my Galaxy S25 Ultra and Sony Walkman NW-A45, analogue playback via Line 1 through my Technics record player and USB playback, I found the range of available source options particularly useful.

This flexibility means that the ULT Tower 7 can be used in several different ways rather than being restricted to a Bluetooth-only party speaker.

Battery and Charging

I have not yet completely discharged the battery, so I cannot give a definitive real-world figure for total battery life.

Sony quotes up to 30 hours of battery life, depending on usage and settings. During my initial testing, I found that using the lighting effects, particularly when synchronised with the music, appeared to reduce the available operating time compared with using the speaker without the lighting effects.

This is not unexpected, as additional features place an additional demand on the battery. I would need to carry out a complete discharge test to provide a definitive assessment.

Charging seemed relatively quick during the period of my testing. However, I have not yet carried out a complete discharge followed by a full charge cycle, so I have not been able to properly test the speaker's specified fast-charging performance.

Microphone and Instrument Inputs

I have tested the karaoke function, including the four different voice modes: Double Tracking, Munchkin, Mouse and Radio.

By far the effect which brought the most fun to the event was Mouse, as everyone enjoyed the way it stretched their voices slightly, changed them to a soft, high pitch and gave them the comic effect associated with cartoons.

I do not play guitar, so I have not been able to assess the guitar/instrument input. I
