Was so pleased to receive the Emberton III Bluetooth speaker. It’s really well made ~ something you’ll notice right away and came with a Quick Start Guide booklet. I had no trouble connecting it to my iPhone or iMac, unlike some other Bluetooth speakers I’ve tried. I already had the Marshall app on my phone so it paired up and in the app you’ll find EQ PRESETS with the first one being that Signature Marshall sound ~ second is PUSH which boosts the bass and treble for a heavier sound and third is VOICE which enhances the midrange for more clarity if you’re listening to voice-focused content. Next on the app is BATTERY PRESERVATION with MAX CHARGE, TEMPERATURE and CHARGING SPEED. I placed my speaker on MAX which limits the charge to 95% and prolongs the battery lifespan. Finally there is ABOUT which tells you the product name, serial number, firmware version and Forget Device option. My firmware was already up to date. Also the app tells you how much battery life is left showing the percentage under Emberton.
I have been testing this speaker quite a bit listening to various kinds of music and taking phone calls. Everything sounds wonderful and voices are very clear. I found I like the first setting on the app which is the Signature Marshall sound. I fully charged it before the first use and after 3 days it’s still at a 68% charge.
I carry it around with me because it’s so portable weighing in at 1 lb. 7.7 oz and measures about 6″ long x 3″ deep x 2.5″ high. The black finish is so cool ~ no worries about it slipping out of your hands.
On top you’ll find a Bluetooth button, power button and in the center a gold Control Knob which is so easy to use. 1. Play/Pause push once 2. Skip Backward/Forward push left/right. 3. Turn up the Volume push up or down. 4. Receive a call push once and 5. Reject a call push twice. There is also a small microphone hole to left of the Control Knob. The colorful, vertical 10 segment battery indicator shows the charge. The USB-C charge power input is on the right side and there is a place to thread a carrying strap if you so choose to although one is not provided. They did include a charging cable.
I can’t say enough about the black finish with that gold MARSHALL in script on the front. BEAUTIFUL!! CLASSIC!! That grill, which is on the front and rear, looks amazing. This model also offers stereophonic sound.
If you are in the market for a superb portable Bluetooth speaker look no further! The price is reasonable and it’s very high quality. It sounds just as good as it looks and I love it! Definitely worth a purchase!

Bluetooth speakers have been around long enough for most of us to own a few around the house or when traveling. We have several upstairs, downstairs, garage, and the backyard. There’s been many I will use when we go on trips. Depending on where we go, I’ll mostly bring our Sonos Move or our Sonos Roam.
The Move packs a big punch and sounds great, but it is cumbersome unless we store it in the car. The Roam, on the other hand, lacks in the sound department but is very easy to throw in a bag for nearby picnics or adventure hikes. I’ve been wanting something that meets both my expectations. I’ve found it with the Emberton III!
This is my first Marshall product, but judging by my satisfaction, it will not be my last. Marshall has several Bluetooth speakers, but this version is small enough to throw in a bag and sounds fantastic. Separation is there, the soundstage is wider than you’d think, and the bass is natural yet clear. Everything sounds so good. It’s not going to meet the sound of a larger speaker meant for home use, but in regards to a “travel speaker,” this is an incredible device.
The Emberton II was a hit when it was released, and I understand why. There were a few adjustments made with this gen, but the look of these keeps the classic amp look Marshall is known for. Everything from the buttons, battery indicator, and speaker grill to the Marshall app screams quality.
The app isn’t super detailed, but it looks great, is snappy, and easy to navigate. When pairing the Emberton III with my Pixel 9 Pro XL, it connected immediately for one of the smoothest pairings I’ve experienced with anything non-Pixel.
Battery life seems outstanding as well. Since the initial charge, I’ve used it four to five times for around 4-5 hours, and according to the app, it’s at 84% battery. That’s awesome! You won’t need to charge this much. Another great thing is when you turn it on, it automatically connects to your phone. There’s no need to go through steps connecting it every time.
For $170, it’s appropriately priced – as that is the standard for this type of speaker. This one sounds much better than many other speakers in this price range. The Sonos Roam is listed at $169, and the Emberton III is night and day better in the sound department to my ears. It’s not near Sonos’ Move, but that’s to be expected due to its $449 price tag! It sits somewhere between The Roam and The Move but is as portable as The Roam is. I’d say the value is there at this price!

So I’ve owned the Marshall Emberton III for about a week now and I love it. It is such a cool “little” speaker. It has a really cool retro feeling yet minimalist design. I like the grills on the front and back of the speaker. The whole speaker has a grippy , rubbery silicone feel. It is very very sturdy, I feel like I could chock a motorcycle tire with it haha. It has rear and front firing speakers for a 360 degree sound experience. The gold button on top is a push button but also toggles up , down, left and right for music controls. It sports the iconic Marshall logo on the front. Stylish all around. Battery life is excellent, I’ve yet to need to recharge it after using it all week. I used it for about 3 hours one night while I painted my bedroom door and doorframe. The battery still shows about 80% battery. I think it will easily last a whole day at the pool or beach with juice to spare. The battery charges with a standard usb C cable. I use my fast charging cable and it charges up in a couple of hours.
Sound quality: is Excellent! For its size. The default sound profile has a well balanced sound. Perfect for rock music. It is quite loud for its size and I think it is perfect for small gatherings, work and play. I think most people would love the sound quality of it straight out of the box but if you’re like me…
I like a litttle more bass in my speakers, so I tweaked it with the Marshall Bluetooth app located in the App Store. It allows you to see battery status, change the EQ and play music easily and conveniently.
Would I recommend it? Yes!
It has very good sound quality, build quality is fantastic. It is rugged, portable and dust / splash proof. Take with you to the pool or barbecue!

I grew up on the idea that bigger speakers are always better. This little waterproof (IP67) and dust resistant wonder is designed to challenge that idea. And of course, this handsome speaker looks like a classic Marshall guitar amp, but only smaller. A lot smaller.
It has no problem at all filling a room with music, and the sound is balanced and natural. Plenty of bass, treble and midrange at an amazing volume without any noticeable strain. But this fantastic sound isn’t confined to one room- you take it with you wherever you go. To the beach, to the office, to the neighbors, and there is no need to hunt for any plug.
On a full charge, you should get 32 hours of listening pleasure. I have been playing with it for only a couple of days, so I can’t fully substantiate that kind of life between charges, but I have no reason to doubt it. The LED row on the top of the device always tells you how much charge you have left, and after my initial listening sessions, it has barely moved.
I love the look and feel of this device as well. It will never slip out of your hand. Its rubber surface grabs and holds on. The big gold button in the center controls playback, such as start stop and pause, next or previous track as well as volume. The on/off and Bluetooth pairing buttons are smaller and the same color as the case, but you can feel them as you run you finger over the case. They are not lighted but are easy to find in the dark with touch. Of course, there is a blue LED that blinks when the device is in pairing mode and goes off when pairing is complete.
The unit comes with a USB-C to USB-C charging cord. No charger is provided. There is also a hardened cutout on the side for attaching a carrying strap, which is not provided. Marshall supplies a color multipage quick start guide.
I pressed the on button and immediately heard the Marshall startup sound. The Bluetooth LED was already blinking, and I hunted for the speaker on my iPhone and paired with it immediately. When I did that, a window opened on my phone and invited me to install the Marshall App which I accomplished in just a few seconds. Even though I plugged the Marshall into a USB charger for a few minutes, nine of the ten LEDs were already illuminated out of the box.
The sound is superb and spacious because it is radiating from both the front and the back of the device, offering both direct and reflected sound. While the Emberton III has two drivers, it did not produce the type of stereo imaging that I would expect to hear listening to left and right stereo speakers placed several feet apart. Who would expect such from such a small device? I got full musical enjoyment from what I heard.
Highly recommended.
