Bromley 750: two-minute review

Expectations are undoubtedly weighing heavily on the Marshall Bromley 750, which is the very first party speaker that the audio specialist has released.

Why? Well first of all, Marshall has had a pretty impressive run in 2025, nailing its typical Bluetooth speaker launches, like the Kilburn III, but
also new product categories, like home theater. But also, Marshalls first party speaker comes with a hefty price tag to match its hefty form factor. Specifically, it will set you back $1,299 / 899 / AU$1,799.

So, can the Bromley 750 maintain Marshalls momentum in 2025 while also competing with the best party speakers around in spite of its considerable cost? Well yes, actually, it succeeds on both counts. Heres why.

First of all, lets talk sound probably the most important aspect of any speaker! The Bromley 750 sounds as youd expect. With its 500W of Class D amplification, youll get almighty bass output, but especially in Dynamic listening mode, youll still be treated to clear, defined mids and expressive, controlled treble.

One of the most interesting additions the Bromley makes is its sound
character control. This lets you adjust audio on a scale of Dynamic to Loud. When you lean more towards a dynamic configuration, youll get a pleasingly nuanced, detailed listen, even in the absence of LDAC or aptX.

However, if you swing things the other way, theres more of an emphasis on raw power. Bass is ramped up and youll get a less analytical listen, but this is very useful if you need maximum loudness for a giant outdoor area, for instance.

Whether youre using Bluetooth, 3.5mm, or USB-C audio, youll be able to adapt EQ to suit your personal needs and taste something I expect from all the
best Bluetooth speakers . However, this doesnt work with the XLR/6.35mm combo ports, which otherwise function without a hitch and offer delay/reverb
effects via the speakers physical controls.

Perhaps my main criticism of the Bromley 750, though, is that its app is sort of disappointing. You cant remotely adapt EQ for the speaker or alter sound characteristics, and theres simply not that much to experience in there.
Thats a shame given that the Marshall Heston 120 made great use of its revamped, feature-rich companion app.

Elsewhere, though, theres still a lot to love about the Bromley 750. I was a big fan of its adjustable lighting, its impeccable 40-hour battery life and its high quality finish to name a few things.

Ultimately, the Marshall Bromley 750 makes for a fantastic debut in the party speaker world. It is expensive, even compared to some similarly-sized rivals, and app controls could be better. Still, this thing offers addictive audio, beautiful lighting, and plenty of playtime. As a result, Id recommend it to those who have the cash.

The Marshall Bromley 750 released in September 2025 and is the audio specialists first ever party speaker. It has a list price of $1,299 / 899 / AU$1,799, meaning it's pretty pricey, but it is constructed of premium materials and delivers extensive battery life alongside powerful audio.

IP54 (Image credit: Future) Marshall Bromley 750 review: features Multiple ports, including XLR/6.35mm slots for karaoke / instruments Entertaining
range of lighting options Impressive 40 hour battery life

The Marshall Bromley 750 is a versatile party speaker, and offers a range of connectivity options to help you keep things fresh. Of course, theres Bluetooth 5.3, but theres also USB-C and 3.5mm ports for wired listening.

Interestingly, though, if you look at the reverse side of the Bromley, you
can also discover RCA ports for keyboards and turntables, as well as XLR/6.35mm combo ports for microphones and electro-acoustic guitars.

One of my colleagues performed Mamas Broken Heart by Miranda Lambert using a mic, and it sounded great. The speaker has delay and reverb effects on-board too, and these worked very nicely indeed. The only other thing worth noting about this is that you cant alter EQ while using the XLR/6.35mm combo ports, which some may hope for.

My favorite feature of the Marshall Bromley 750 is certainly its integrated stage lights. There are three different modes an ambient setting, and two dynamic alternatives that react differently depending on audio output. The lights look absolutely fantastic, and really help to further immerse
listeners in the music. You can also trigger a burst of strobe lighting by pressing the M button.

Speaking of the M button, its function can be altered in the Marshall app.
But this isnt the shiny new version of the app used by the Marshall Heston
120 soundbar: its the older variant. Unfortunately, the app feels a little underbaked. You can alter volume, listen to an Auracast broadcast, or adjust the standby timeout, but thats about it.

I wish the app enabled EQ adjustment something that you can access with physical controls. The app also omits control over the reverb and delay effects for karaoke and instrument use. It would also be good to have control over the new sound character feature which enables you to tailor audio more towards a dynamic or loud style.

Back to the positives, though, and I have to say that the Bromley 750s
battery life is excellent. 40 hours of playtime for a speaker of this size? Thats phenomenal. A similar-sized rival like the JBL PartyBox 720 is capable of up to 15 hours, which is fairly standard that really puts the Bromleys massive playtime into perspective.

On top of that, the Bromley 750 has a replaceable battery, which means that even if your 40 hours of play run out, you can substitute another one in to extend the party. Theres no multi-speaker pairing, which some may miss, but otherwise there are a lot of features to enjoy on Marshalls debut party speaker. Features score: 4.5/5 (Image credit: Future) Marshall Bromley 750 review: sound quality Mighty 500W power output Meaty yet regimented bass performance Sound character control works great

The Marshall Bromley 750 isnt necessarily the most powerful party speaker on the market, but believe me, it can get plenty loud enough for just about any setting.

I brought the speaker to the parking lot outside Future Labs and listened to some house tunes with my friends, and it was almost as if I threw my own mini-rave. In fact, one colleague inside the office noted that they could
hear the Bromley while using ANC headphones pretty impressive, right?

But it's one thing being powerful, and another sounding great. Luckily, the Bromley 750 does both.

When bumping Cant Resist by Jamback, the high-pitched percussion cut through with intent, never sounding harsh, even at high volumes. Vocals in the mid range weren't obscured in the mix, either, even with the tracks deep bass pumping throughout. The rapid kick drum never sounded lethargic and low-frequency output was both textured and impactful. The speakers ability to reach down to 20Hz means that it can also handle sub bass with finesse.

Similarly, with Unknown Territory by Kolter, high-pitched percussive elements were expressive yet controlled, while the bass sounded seriously meaty but also well-regimented. Spacey synths were also well separated, enabling a decently nuanced listen, even in the absence of higher-resolution audio
codecs like LDAC or aptX.

The sound character control function works very well on the Bromley, and
makes it a versatile speaker for more lowkey indoor occasions or busy outdoor gatherings. At the music testing room at Future Labs, I tuned into Are You Gonna Go My Way by Lenny Kravitz it's only right to listen to some Rock on a Marshall speaker, after all.

Here, I set the dial almost entirely towards Dynamic. With this setting, bass was balanced, not overbearing, giving vocals the space to sound clear and defined. Now, when I tried cranking up loudness to the three-quarter mark and beyond, bass was too smothering for the setting, resulting in a more compressed, one-dimensional quality.

But again, this isnt the sort of situation where youll need to depart too far from dynamic listening. And even outdoors or in large indoor spaces, you'll likely be able to keep the dial somewhere between Loud and Dynamic, where audio still sounds fantastic. Even if you do set loudness to the max, youll still be treated to almighty bass, and get all the power you need for use in
a huge, busy outdoor environment.

One more thing the Bromley 750 has an impressive soundstage thanks to the
use of Marshalls 360-degree true stereophonic sound. This works well, and creates a wide, well-adjusted sound from almost any listening angle. Sound quality score: 4.5/5 (Image credit: Future) Marshall Bromley 750 review: design Classic Marshall look is a hit once again Beautiful lights and
physical controls Very hefty, but handle makes it easy enough to transport

If youve read my Marshall Kilburn III review or basically any piece about Marshall products youll know that I typically love the way the audio specialist designs its products. And the story remains the same for the Bromley 750, which looks brilliant as well.

I adore the premium speaker grille and the way its shimmering lights beam behind it. Im also partial to the faux-leather exterior, luxurious physical controls, and easily accessible connectivity ports.

Now, lets address the elephant in the room the Bromley is one hefty lad.
Yep, at 52.7lbs / 23.9kg, you may not think this thing is the easiest to lug around. But luckily, the Bromley is equipped with a suitcase-style handle and wheels, meaning you can roll it around to wherever you want to place it. Wheeling it rarely felt clunky, making it easy enough to transport.

On top of that, the Bromley has handles on either side if you need to lift it up some stairs, as I did.

Another aspect of design worth discussing is the Bromley 750s IP54 rating. This means that it has some limited dust protection, as well as shielding against water splashes from any direction.

Now, is an IP54 rating anything special? Well, perhaps not. But still, for a speaker of this kind, it's certainly in-line with the competition. And it still goes a step further than many thanks to a drainage function, which dislodges any excess moisture in the case of a particularly rainy day, for instance. Design score: 5/5 (Image credit: Future) Marshall Bromley 750 review: value Comes at quite the cost But does offer plenty of quality in return for investment Repairability can likely boost longevity too

The Marshall Bromley 750 is by no means cheap. It has a list price of $1,299
/ 899 / AU$1,799, meaning that it will be a real investment even compared to some rivals in this weight and size class.

For instance, the JBL PartyBox 720, which was released at around the same time, is not only more powerful than the Bromley 750, but cheaper too $200 / 100 / AU$300 cheaper, to be exact.

In fairness, though, Marshall offers slightly better protection against the elements, much better battery life, and a more luxurious look than its rival from JBL. Is that worth the extra cash? Well, that will just depend on your needs and preferences.

Even if the Bromley is expensive, a couple of things make it well worth the investment. First of all, it's an absolute beauty. This thing is a statement piece you wont necessarily have to wheel it away to your garage for future use. It could conceivably fit into a living room set up for personal
listening and for aesthetic purposes.

Secondly, the Bromley 750 is repairable, with Marshall offering authorized repair services as well as spare parts for its first party speaker. Pair that with the replaceable battery, and this model feels well protected against future wear and tear.

Of course, this is also an excellent-sounding, fairly feature-rich party speaker, so even if the price tag is high, youll get oodles of quality for
the spend. Value score: 4/5 (Image credit: Future) Should I buy the Marshall Bromley 750?

Youre a regular party host
If youre someone that loves to throw a good party every now and then, the Bromley 750 could be a great investment. Awesome audio, buckets of power, and karaoke capabilities what more could you ask for?

You love the Marshall look
If youre a fan of the Marshall aesthetic, then youll almost certainly be rocking with the Bromley 750 as well. With an attractive faux leather exterior, high-quality grille, and gorgeous lighting, youre in for a treat with this one. Don't buy it if...

Youre looking for the ultimate value pick
The Bromley 750 is an expensive beast, and a few similar-sized rivals are available for a little less too. Of course, youre getting almost unbeatable battery life and fantastic build quality here, but youll have to assess whether thats worth the additional spend over competitors.

Youre a little low on space
If you dont have a healthy portion of space, the Bromley 750 may be overkill for you. At 25.7 inches / 652mm tall and 16.3 inches / 413mm wide, this thing will require some serious room and with a weight of 52.7lbs / 23.9kg, it's pretty heavy too. Marshall Bromley 750 review: also consider

JBL PartyBox 720
OK, weve not reviewed this one just yet (watch this space though), but it's one of the obvious rivals to the Bromley 750, so it's worth a comparison. The PartyBox 720 has much more in-your-face multicolored lighting, as opposed to the more ambient style of the Bromley 750 some will like that, others may find it overbearing. As I mentioned earlier, this model is more powerful, yet still cheaper than the Bromley, though that comes at the cost of no dustproof rating and a significantly smaller (yet still solid) battery life.

LG xboom Stage 301
Here's something a little different (and significantly cheaper). The LG xboom Stage 301 is a wedge-style Bluetooth speaker that offers deep yet clean bass output, effective AI-assisted audio output, and immersive dual-bar lighting. It also supports karaoke and DJ modes. If you don't quite need all the power of the Bromley 750, this could be a strong smaller option for you. Read our full LG xboom Stage 301 review . How I tested the Marshall Bromley 750 (Image credit: Future) Tested across the course of one week Used indoors at Future Lab and outdoors in a parking lot Predominantly tested using Tidal

I tested the Marshall Bromley 750 across the course of one week, spending
most of my time with it at the music testing space at Future Labs, but I also spent a while with it in the parking lot as well.

During the testing period, I spent hours on end blasting tunes from a variety of genres, with bass-heavy bangers and legendary rock ballads as starring players. I ran through the TechRadar testing playlist , which is standard practice for me when trialing audio gear, but I also tuned into some songs from my personal library .

When listening to music, I typically used Tidal , but I also tried bumping some tunes from my library on Spotify in light of the recent lossless update
. I listened at a variety of angles and volumes, exhausted all of the
lighting options, and messed around with the Bromleys karaoke and instrument capabilities. First reviewed: October 2025 Read more about how we test
