*This article contains advertisements (Amazon Associates). Please check the links for current pricing and stock availability.
Marshall's "Emberton III" is a portable Bluetooth speaker that is slightly larger than the palm of your hand. With its classic black-and-gold design characteristic of the brand known for guitar amps, a long playback time of up to 32 hours, and IP67 dust and water resistance, it has gained popularity among those who want a single device to use both at home and on the go. On the other hand, if you choose it solely because it "looks cool" or is a "famous brand," it is a product that can easily lead to regret, with users feeling it "wasn't what I expected" in terms of size and functionality.
This speaker has a different positioning than so-called large stationary speakers. It is designed with the premise of being used while moving it between the kitchen, bedroom, balcony, or campsite, in a size that is easy to carry around. Therefore, to be honest, it is easy for evaluations to vary if you compare it simply by "loudness" against stationary models in the same price range or larger portable units.
In this article, I have summarized who the Emberton III is for, how it differs from competitors and higher/lower-end models, and points you should check before buying, in a way that is easy to understand even for those choosing a speaker in this price range for the first time. In conclusion, it is a strong option for those who want a good balance of portability, design, and long playback time. On the other hand, those who want to fill a large room with high volume or those seeking more versatile smart features might want to consider other directions, which I will introduce later. Prices fluctuate depending on the time of year, so it will be easier to make a decision if you read while checking the latest prices on Amazon.
First, the conclusion: The Marshall Emberton III is a strong choice if you prioritize portability
The Emberton III is a speaker chosen not only as a tool for playing sound but also as a companion that you can easily carry from room to room, and from home to the outdoors. It is a strong candidate for those who find the following points attractive.
Long playback time of up to 32 hours: It has enough capacity to keep playing for over a full day on a single charge, and is designed to minimize the hassle of frequent charging. It also supports fast charging, allowing it to recover to a certain level with just a short connection.
IP67 dust and water resistance: With a rating that prevents dust ingress and withstands short-term submersion in a certain depth of water, you can use it without worrying too much in the kitchen, in front of the bathroom, on a rainy balcony, or outdoors.
Sound dispersion close to 360 degrees: Designed to emit sound from both the front and back of the unit, the sound naturally wraps around the area where it is placed. This method is well-suited for situations where people are gathered around it.
Brand-typical design and operation feel: With its black-and-gold texture and intuitive operation via the joystick (knob-type control button) on the top, it is a unit that creates an atmosphere just by being placed there.
It is especially suitable for the following people:
Those who want to use one unit while moving it between multiple rooms in the house.
Those who have opportunities to take it outdoors, such as to campsites or balconies.
Those who value not only sound quality but also the appearance and the atmosphere it creates when placed.
In terms of price range, the Emberton III is generally a portable speaker in the 20,000 yen range. It is by no means the cheapest price range, but considering that you can get design, waterproofing, and long playback time all at once, it is a level that is easy to accept. The criteria when in doubt are simple: if you want to "fill a room with high volume," consider the higher-end models or large units mentioned later, and if you want a "balance of portability and design," the Emberton III will meet your needs. First, check the current selling price and compare it with your own priorities.
What you can do with the Marshall Emberton III
The Emberton III is a standalone wireless speaker that you can start using without adding complicated wiring. The main uses are as follows:
Wireless playback from smartphones and PCs: It supports Bluetooth, allowing you to easily play music from your smartphone or tablet. Pairing (the initial setup to connect devices) is also relatively simple.
Playback outdoors and in wet areas: Thanks to its IP67 dust and water resistance, it is easy to use in situations such as the kitchen, in front of the bathroom, on balconies where you might worry about rain, or at campsites and picnics.
Long-lasting continuous playback: Supports up to 32 hours of playback, a design that makes it easy to enjoy background music from morning to night or even during a full day outdoors without worrying about running out of battery.
Using two units together: You can use the dedicated app to pair compatible speakers and play the same song simultaneously. This is convenient when you want to deliver sound across a large space or in separate rooms.
Sound adjustment via dedicated app: You can adjust the sound balance (such as the amount of bass and treble) to your preference using the free smartphone app, allowing you to change the impression of the sound depending on the listening environment or music genre.
While it is not the type of device that markets itself on flashy multifunctionality, the Emberton III's character lies in consolidating the basic experience of 'carrying, connecting, and playing' with a high-quality appearance and long playback time. Even for those unfamiliar with smartphone operations, once the initial pairing is complete, it can be used simply by playing music from your usual music app, which is one of the reasons it is easy to live with for a long time. It blends naturally into various aspects of life, from daily background music use to taking it outside on your days off.
Differences from competitors and higher/lower-end models
When considering the Emberton III, it is easier to make a choice if you understand where the dividing lines are compared to the rest of the Marshall lineup and other popular portable speakers from other companies. I have organized the overall picture in the diagram below.
Broadly speaking, there are three main points for judgment:
Size and volume orientation: The Emberton III is a size that can be held in one hand and excels at providing volume for individuals or small groups. Even within the Marshall brand, the higher-end Middleton is a size larger and can produce louder sound and more powerful bass. Conversely, the lower-end Willen is even smaller and is suited for desks or bedside tables. The basic distinction is that if you want high volume in a large room or outdoors, go for the higher-end model; if you want something small to carry around, go for the lower-end model; and the Emberton III is the balanced model in between.
Differences from other companies' waterproof portable devices: In the same price range, there are also waterproof portable speakers from brands like JBL, Bose, and Sony. Many of these are multifunctional products with features like microphones for calls or lighting, whereas the Emberton III is a model that prioritizes design, sound cohesion, and long playback time over the number of features. Even with the same budget, your satisfaction will depend on whether you choose multifunctionality or the brand's worldview.
Generational differences (the meaning of being 'III'): The Emberton III has updated its waterproof rating, playback time, and connectivity with each generation while maintaining its aesthetic atmosphere. If you are choosing a previous generation through second-hand markets or sales, it is reassuring to check, as the waterproof rating, playback time, and supported features may differ from the current model.
In terms of price difference, the higher-end Middleton is about 20,000 yen more expensive than the Emberton III, while the lower-end Willen is around 10,000 yen and more affordable. In other words, the Emberton III's position is distinguished from models above and below it, as well as from other companies' devices, in terms of 'easy-to-carry size,' 'balance of design and sound,' and 'long playback time and waterproofing.' By prioritizing what you value most, you can see if the Emberton III is the best fit for you.
Points that are easy to get stuck on before buying
Since the price is not exactly cheap, I will list the judgment criteria you should organize in advance so that you don't end up thinking 'this isn't what I expected' after purchase.
Room size and volume
The Emberton III is designed to excel at volume levels suitable for an individual room or for a small group gathered around it. Conversely, for uses like filling a large living room with high volume or letting a large crowd listen in a wide outdoor space, it may feel insufficient. The reason to consider this first is that the volume and amount of bass a portable speaker can produce are determined to some extent by its size, and they cannot be increased later. It is less likely you will fail if you imagine the size of the space where you will mainly use it and then judge whether this size is sufficient or if a higher-end model is necessary.
Waterproof rating and usage compatibility
IP67 is a rating that 'withstands submersion for a certain period at a certain depth,' but this does not mean it is 'absolutely indestructible under any water exposure.' Regular use in the bath or leaving it submerged in water for long periods may not be intended. The reason you should check this is that the waterproof rating is only a guideline under test conditions, and unintended usage may not be covered by the warranty. It is reassuring to check before purchasing whether your intended usage scenarios (rainy balcony, kitchen, poolside, etc.) are within the expected range.
Usability of the call microphone
The Emberton III features a built-in microphone and supports hands-free calling when connected to a smartphone. The reason this is a key decision factor is that for those who want to handle quick calls on their speaker in addition to listening to music, the presence of a built-in microphone can significantly impact usability. However, since this is a product primarily designed for music playback, if you prioritize call quality or voice-only operation, it is safer to compare it with dedicated smart speakers or models specialized for calls before making your decision.
Checking the charging port and included accessories
Charging uses USB-C (the newer, reversible connector), but depending on the model, even if a charging cable is included, the adapter (power plug) for the wall outlet may be sold separately. The reason to check this is that if you cannot charge it immediately upon arrival, it will delay your ability to start using it. Since you can often use your existing smartphone adapter as a substitute, it is smooth to check if you have a USB-C charging environment at home before purchasing.
Who it is for and who should reconsider
Based on the information so far, I will summarize who the Emberton III is suitable for and who might want to pause and reconsider. Please also refer to the diagram below.
Who it is for
People who want to use one unit in multiple locations: It is lightweight and easy to carry, making it suitable for those who move frequently from room to room or from inside the house to the outdoors.
People who want to use it freely outdoors or near water: With an IP67 dustproof and waterproof rating, you can use it without worrying too much about rain, dust, or splashes.
People who value design and atmosphere: Those who find value in the Marshall-esque look are the type most likely to be highly satisfied.
People who want to reduce the hassle of charging: With up to 32 hours of playback, it is designed to be easy to use without needing to charge it frequently every day.
Who should reconsider
People who want to fill a large room with loud sound: At this size, there are limits to volume and bass, and you will likely be more satisfied with the higher-end Middleton or a large stationary unit.
People who want to perform many operations using only their voice: While it supports hands-free calling, this device is primarily for music playback. If you prioritize usage that involves constantly calling out to a voice assistant, it is safer to include smart speakers in your comparison.
People who just want to keep costs as low as possible: If you are not particular about design or waterproofing, there may be more affordable products that can meet your needs.
People who want to pursue sound quality in a stationary setup: If sound quality is your top priority over portability, there is also the option of choosing a stationary speaker for the same budget.
Things to check before buying on Amazon
To ensure you don't regret your purchase, I recommend checking the following points before clicking the order button. I have added the "reason why you should check" for each.
Current selling price and price trends: The prices of portable speakers fluctuate due to sales and model changeover periods. To determine if now is the right time to buy, check the latest price. As a general guide, the market price is in the 20,000 yen range.
Check if the seller is an authorized retailer: Verifying if the item is shipped by the manufacturer or Amazon directly provides peace of mind regarding initial defects and warranty support. For extremely cheap listings, always check the condition and warranty terms.
Contents of accessories (cables/adapters): Checking the product page to see if everything needed for charging is included and if no additional purchases are required will ensure you can use it as soon as it arrives.
Actual color and size: The color may look different in person than in photos, and sizes often feel larger or smaller than expected when looking at numbers. Check if it fits your intended placement or portability needs.
Warranty and support conditions: Checking the manufacturer's warranty period and any notes regarding waterproofing will help you stay calm and prepared in the unlikely event of an issue.

Frequently Asked Questions
Q. Can it really be used for 32 hours continuously?
A. The maximum of 32 hours is an estimate provided by the manufacturer, and it will be shorter if the volume is set high. However, at reasonable volume levels, it can often be used for over a full day on a single charge, and it is designed to minimize the need for frequent charging. It is a level that allows for worry-free use during long outings or outdoor activities.
Q. Is it okay to use in the bathroom?
A. With an IP67 dust and water resistance rating, it is designed to withstand splashes and temporary submersion, but regular use in the bathroom or prolonged submersion may be outside of its intended use. It is recommended to check the manufacturer's warnings, including those regarding steam and high-temperature environments, and use it within reasonable limits.
Q. Can I use it for phone calls with my smartphone?
A. The Emberton III has a built-in microphone and can be used for hands-free calls when connected to a smartphone. If you prioritize call quality, it is easier for the other party to hear you if you use it in a quiet environment. Since this product is primarily designed for music playback, if calls are your top priority, it is safer to compare it with models specialized for calling.
Q. Can I make the sound louder by connecting two units?
A. You can use the dedicated app to pair compatible speakers and play the same song simultaneously. This is convenient when you want to deliver sound to a large area or separate rooms, but if you want to increase the maximum volume of a single unit, higher-end models or larger devices are more suitable.
Summary: A strong contender if you want a balance of portability and design
The Marshall Emberton III is a device that strikes a good balance between ease of use as a portable speaker and the brand's signature design. Finally, here are three key points to consider when choosing.
Attractive portability and long playback time: With a size that can be carried in one hand and up to 32 hours of playback, it is designed to be easily used both at home and on the go.
Combines waterproofing and design: The IP67 dust and water resistance makes it durable for wet areas and outdoor use, while you can also enjoy the classic Marshall look. The market price is around the 20,000 yen range.
Other options if you want high volume or multi-functionality: If you need volume to fill a large room or a dedicated call microphone, it is worth considering the higher-end Middleton or multi-functional models from other companies.
Once you clarify where you will use it and what your priorities are, it will become clear whether the Emberton III is the perfect device for you. Since prices and stock levels fluctuate over time, checking the latest status before purchasing will help you make a choice you won't regret.
