    GOAT Speaker

    I never write reviews but this speaker is so good that I just had to. 10/10 recommend completely. The bass and treble are really good and the sound is so phenomenal that it feels like the music is being performed right in front of you. If you have doubts about this speaker, don’t because you will get your mind blown. For a small looking speaker it can really get to work in the sound department. Get it if you’re considering buying it.

    The Marshall speaker is really good—great sound and easy to use anywhere. You can connect it at home, on the go, or even in your car. Stylish design with strong, clear audio every time.

    Well worth the $$. I am extremely happy with the sound & ease of use. It looks extremely pretty, contrmporary, macho in just about any room of the house. I would gladly buy the exact same model if i ever needed to. Ive had it for the past 15 months. 05/2025. [It is only plug in type (no battery).

    I bought the Acton III recently and absolutely love the audible quality it exherts. I have never been so satisfied purchasing a speaker that explodes your music while keeping the music playing crisp. I enjoy taking this outside in my back porch and play whatever the mood I am in. I do wish I could take it anywhere I could like a jobsite but you'll need somewhere to connect power. Overall, for the simplicity in design, the quality of material and most importantly the sound it delivers, I will not be going to any other brand such as JBL anytime soon.

    Big Sound, Classic Style

    As an amateur music lover, the Marshall Acton III has completely elevated how I enjoy music at home. The iconic Marshall design is a standout — vintage, stylish, and solidly built. Sound-wise, it’s honestly a game-changer. I may not be an audiophile, but everything I play sounds noticeably richer and more detailed. The bass is warm and balanced, vocals are crisp, and the overall sound feels immersive, no matter the genre — whether it’s acoustic, indie, or old-school rock. The setup was simple, and the Bluetooth connection is super reliable. I also love the physical knobs — they make fine-tuning the sound feel more personal. If you’re someone who truly enjoys music and wants a speaker that delivers both quality and character, the Acton III is absolutely worth it.

    We really like the sound and look. Deep base, and clear high ends from a somewhat compact speaker. The form factor is the best part of this. First saw one of these at a boutique hotel but it didn’t work. Then an AirBnb had one so we got to really play with it. Overall, worth it to have a few good speakers in your home and this one both looks and sounds great!

    This is hands down my favorite purchase that I have bought the entire year. This speaker is a good medium size with bluetooth compatibility and I was so shocked when I first started playing it and the sound quality was SO GOOD. You can adjust the bass and you can hear sounds that youve never heard before. Who needs to go to a concert when you can just listen to this speaker?

    This is an overall amazing speaker. I love it so much I find myself needing to order another one. We use it for our records and now I want one for the other room so I don't go without this excellent sound. Plus it just has that classic look and it is so simple to set up with bluetooth!!

    Awesome speaker

    I got this speaker for my small apartment and it works wonderfully. It fills the room with superb sound quality. Not only does it sound nice, but it is built beautifully. It is obvious that this speaker is built with quality materials and is designed to last a very long time. I also found that this speaker performs much better in small rooms vs big rooms, specially on the low end of the sound, I have experienced much more bass in smaller rooms, however this is expected. All in all, this is just such a high quality product and it is worth the price tag. For its size, this speaker has surprisingly good bass, great treble and gets more loud than you would probably need, just a great product.

    The sound quality is great, with easy to use controls. The design is awesome. Marshall cabinet, enough said. The unit times out its connection after being left alone. This means you can walk away and not still have your audio connected. Simple toggle switch allows for easy/quick reconnection/connection.

    Fantastic sound at low or high volume. I wanted something I could get some bass out of but still move around the house. This speaker has been fantastic for that. It does need to be plugged in, but it produces great sound.

    I use this with the aux connection with my Sony record player and a Sony CD player (using RCA to aux adapter) Honestly I love the size and sound that comes out of this thing! I live in an apartment so I can't play it too loud but it's been pretty reliable in the few weeks I've had it Keep in mind the device needs to be plugged in to use, it's not a wireless speaker it needs a power source

    (I got the excellent open box) This is actually a great sounding speaker, i think its very comparable to the harman kardon onyx 7 but a little louder with less bass. Premium build quality, its the real deal. It looks good but i wish it haf a battery, i understand it wouldnt get as loud and would be more expensive. I keep coming back to onyx just because of the battery and portability. It is great to keep in a room and stay there. The bass distorts at almost to full volume. I would recommend for the 170 bucks i paid, i just dont know about the retail price.

    I love this Marshall Acton III Bluetooth speaker. The sound is incredible, and it allows you to adjust the base and treble that enriches the sound experience. This speaker also looks great on your table or shelf. If you want a great sounding and loud Bluetooth speaker, then I highly recommend the Marshall Acton III.

    Wow. I've been all over the place searching for a good, powerful bluetooth speaker to plant next to my record player. I kept wanting Bose but kept getting put off by the cost and the recent look. I'd rather a retro boxy sort of tivolo aesthetic. I got this because it was worth a shot, on a sale and the return policy is so good. Looks: It looks and feels seriously authentic. This is not a cheap plastic modeling of a Marshall amp-- this is just a mini one with modern bells and whistles. It's SIGNIFICANT in weight the way a steel digital SLR feels compared to a newer plastic one. It's got the heft, the quality of the leather is the same as a concert one. It's not getting scuffed easily, it's not going to break anytime soon. I LOVE it. The highlighted digital lights on the top are red. the volume dial has red lights showing the music levels. the toggle buttons for on and off admittedly makes the music nerd in me way too excited for that analog feel. And the sound? YES! This thing has some serious power. I love the treble/bass levels you can adjust-- simple and just enough for something in this price point-- and no messy apps to manage it. It is right in front of you like the way you want it to be. But I feel like Marshall really has one up on Bose for this price range-- it really feels like a legit concert in your house. With zero tinittis flaring (elder millennial here) from dissonance. With the bass fully up it's a perfect balance of CLEAN sound but just a LITTLE dirty bass to really make it so powerful like a full stack right by the pit at a show. Love it. So glad I went with it. Easily the best speaker I have. I would never dream in a million years my turntable is transmitting my records via bluetooth to this speaker. It's as awesome sounding as my dad's Fischer receiver and speakers from the 70's. that's saying something.
