Marshall Emberton III: Two-minute review

Without a doubt, nan Emberton III is 1 of Marshall's best Bluetooth speakers pinch agelong artillery life and awesome sound considering its comparatively mini size. This 3rd procreation Emberton delivers moreover amended artillery life and somewhat louder sound, and while it's not going to rattle nan rafters it's an awesome performer.

The Emberton III is peculiarly bully astatine little volumes wherever Marshall's Dynamic Loudness delivers a bass boost that prevents your euphony from sounding excessively weedy; for podcasts, wherever voices thin to beryllium little frequencies, there's an EQ preset to trim nan lows and boost nan mid-range instead.

The main trading constituent present is simply a characteristic we weren't capable to test: Auracast via Bluetooth LE. Auracast will alteration you to create a multi-speaker setup pinch your Marshall arsenic nan sound source, broadcasting complete Bluetooth to different Auracast-capable Marshalls, but nan characteristic hasn't yet been implemented. It's coming arsenic an over-the-air update via Marshall's smartphone app and Marshall tells america it's coming very soon. Basically, it's built to beryllium LE Audio ready, truthful if future-proofing your Bluetooth strategy is thing you're into, it's a awesome buy.

With speakers this mini location is of people a limit to really overmuch bass they tin put retired and really large they tin spell earlier things commencement getting harsh.

Marshall Emberton III review: Features

  • Bluetooth LE and Auracast ready
  • 32+ hours of artillery life
  • "True Stereophonic" audio

You tin group up nan Emberton III successful 2 ways: straight done your device's Bluetooth, aliases via nan Marshall iOS aliases Android app. That gives you entree to 3 EQ presets: nan default "Marshall sound"; a debased and precocious extremity boost; and a mid-range boost. That second 1 is for reside specified arsenic audiobooks and podcasts. As pinch nan erstwhile exemplary location are nary EQ customization options.

Using nan instrumentality is very simple, because it's a very elemental device. There's an on-off button, a rocker move for measurement and way skipping, and a reddish LED portion to show artillery life.

The large news present is nan upgrade to Bluetooth LE audio and Auracast multi-device broadcast support. With Auracast you'll beryllium capable to stock your euphony to aggregate speakers simultaneously, but nan Bluetooth LE it requires won't beryllium disposable connected motorboat day: Marshall promises an update imminently via nan Marshall Bluetooth app but of people that intends we weren't capable to effort that circumstantial feature. There's besides built successful microphone truthful you tin usage this Marshall for calls, but not for sound assistants.

As pinch nan erstwhile Emberton, nan Emberton III has what Marshall calls True Stereophonic, a 360-degree audio characteristic that promises to capable your room pinch amazingly large sound. Oh, and there's a strap for your backpack truthful you tin annoy group connected hikes.

One of nan issues pinch galore speakers is that they tin go excessively bass-light astatine debased levels because audio characteristics alteration pinch volume. Marshall has a solution that it calls Dynamic Loudness, which automatically adjusts nan tonal characteristics based connected nan measurement you're listening at.

Battery life is simply a claimed 32-plus hours, 2 much than before, and we didn't person immoderate problems achieving 30 hours pinch playback volumes astir 50%. Full recharge via nan USB-C larboard takes 2 hours compared to 3 for nan Emberton II.

In a bully touch, nan Emberton III plays a tiny small ascending guitar riff erstwhile you powerfulness it connected and a descending 1 erstwhile you powerfulness it off.

  • Features score: 4.5/5

Marshall Emberton III review: Sound quality

  • Dynamic Loudness awesome astatine little volumes
  • EQ boost for podcast and audiobooks
  • Punchy fixed its mini size

It'd beryllium rude not to commencement testing pinch immoderate classical rock, truthful nan first opus to effort was people AC/DC's Back successful Black. The Emberton delivered an impressively punchy capacity pinch fantabulous mid- and high-range clarity, and nan committedness of room-filling sound was decidedly delivered: this small speaker rocks overmuch harder than you'd expect it to and doesn't request you to position it cautiously to get nan champion results.

That said, it's important to negociate your expectations pinch a speaker of this size. There's only truthful overmuch aerial that two-inch drivers tin push, truthful while Marshall has done a bully occupation delivering debased frequencies astatine little volumes – truthful overmuch truthful that you mightiness want to switch to nan mid-range EQ boost for podcast listening truthful nan presenters don't make everything astir you vibrate – erstwhile you crank up nan Emberton to higher volumes nan debased extremity distorts and nan higher frequencies go harsh.

With Marshall amplifiers, it's accepted to move them up. But this Marshall speaker is champion turned down. At little volumes nan Dynamic Loudness delivers very awesome bass for a strategy this small. REM's Out of Time medium was a peculiar highlight, Mike Mills' bass arsenic clear arsenic his harmonies.

The comparative deficiency of bass astatine higher volumes is peculiarly noticeable connected creation euphony specified arsenic Pet Shop Boys' Loneliness, Troye Sivan's slinky One of Your Girls aliases Charli XCX's 360, each of which suffer a batch of their floor-filling thump, and pinch expensively produced tracks specified arsenic Taylor Swift's No Body No Crime, which has a very unique bass drum sound that loses its punch here. All of these tracks sound amended quieter connected this system.

That's besides an rumor for guitar-based stone music, particularly comparatively engaged tracks specified arsenic The Killers' When You Were Young. It's nosy astatine little volumes but move it up and it quickly becomes tiring.

To my ears this is simply a speaker champion suited to bedroom, room aliases study listening and for taking extracurricular connected bully days. If you're looking for a statement monster aliases intend to perceive large you mightiness beryllium amended pinch thing built astir larger speaker drivers.

Marshall Emberton III review: Design

  • Looks for illustration a Marshall amp
  • IP67 for particulate and h2o resistance
  • Rugged and stackable

The Emberton III unsurprisingly looks a batch for illustration nan Emberton II. As pinch different Marshalls nan creation echoes that of nan celebrated Marshall cabinets and stacks we've seen connected stone stars' stages, and that intends they're beautiful rugged-looking and no-nonsense arsenic good arsenic stackable, conscionable for illustration shape speakers. I deliberation they look great; having Marshall's creation DNA successful speakers makes much consciousness to maine than crowbarring it into headphones specified arsenic nan Marshall Major III, which I deliberation conscionable look overly boxy. You tin take betwixt a classical achromatic aliases cream.

The caller Emberton is rated IP67 for particulate and waterproofing, truthful it's tin of surviving a dunk arsenic heavy arsenic 1m of h2o for up to 30 minutes. That makes it mostly immune to a spilled portion aliases show rain.

Inside nan Marshall location are 2 people D amplifiers pushing copy 10W 2-inch afloat scope drivers and 2 passive radiators. Frequency consequence is 65Hz to 20kHz and it's somewhat louder than before, pushing retired a sound unit level of 90dB astatine 1m compared to nan 87dB of nan Emberton II.

The Marshall, thankfully, is simply a batch lighter than nan Marshall amps I've had to lug up and down stairs and occurrence escapes: it's 0.67kg/1.5lbs.

  • Design score: 4.5/5

Marshall Emberton III review: value

  • Lots of awesome competitors successful this value bracket
  • Marshall's artillery life leaves galore rivals behind

At $159 / £159 / AU$289 this speaker is competing against immoderate very awesome rivals: walk £20 much and you could get our existent favourite among nan best Bluetooth speakers, nan Sonos Roam 2. But wherever nan Marshall has nan Sonos speaker beaten is successful artillery life.

The Sonos promises up to 10 hours whereas nan Marshall tin present much than 3 times that. So if you're going to a play show aliases anyplace other wherever location comforts will beryllium absent for a fewer days, nan Marshall is nan speaker you'll want to return pinch you. It's mini capable to beryllium genuinely portable but large capable to soundtrack your adventures without having to push it excessively hard.
