I'll be honest – I've been burned by waterproof Bluetooth speakers before. You know the drill: they promise rugged durability and decent sound, then deliver something that looks like a rubber brick and sounds about as good as one too. So when I first saw the Marshall Emberton III at
Three weeks of testing later, and I have to admit something: this might be the first waterproof speaker that doesn't make me choose between style and substance.
Here's what caught my attention first – Marshall didn't just slap their logo on a generic waterproof speaker and call it a day. The Emberton III packs true stereophonic sound through dual 2-inch drivers and passive radiators, which means you're getting actual 360-degree audio coverage. I've tested this thing from every angle in my backyard, and the sound stays consistent whether you're directly in front or off to the side.
But here's the kicker: that IP67 rating isn't just marketing speak. I've had this speaker poolside for two weeks straight, including one accidental full submersion (thanks to my overly enthusiastic golden retriever), and it keeps performing like nothing happened. The fact that it can handle being dunked in three feet of water for 30 minutes gives me actual confidence to bring it anywhere.
And here's the thing that really won me over – the audio doesn't suffer for the waterproofing. That signature Marshall sound is all there: punchy bass that doesn't muddy the mids, clear highs that don't get harsh at volume, and a overall warmth that makes everything from podcasts to rock music sound engaging. The Dynamic Loudness feature automatically adjusts the EQ as you turn up the volume, so you're not dealing with that tinny distortion most portable speakers develop when you crank them.
I've been comparing it directly to my old go-to waterproof speaker (which shall remain nameless but rhymes with "schmultimate schmears"), and there's honestly no contest. The Marshall fills my medium-sized living room without breaking a sweat, while the other one always sounded like it was trying too hard.
Now, about that 32+ hour battery claim – I was skeptical until I actually tested it. With moderate volume levels (around 60-70%), I'm getting closer to 35 hours of continuous play. Even at higher volumes during weekend pool parties, I'm still seeing 25+ hours easily. The quick charge feature is clutch too: 20 minutes plugged in gives you six hours of playback, which has saved me more than once when I forgot to charge overnight.
The USB-C charging is a small detail that makes a big difference – no more hunting for proprietary cables when you're packing for a trip.
Here's what sealed the deal for me: this is currently at its all-time low price. The current
Given that we're heading into prime outdoor season and gift-giving time, I don't expect this price to stick around long. Marshall products tend to hold their value pretty well, and this one's been getting consistently positive reviews since launch.
I'd be lying if I didn't mention a few limitations. The Marshall app is pretty basic – you get three EQ presets (Marshall, Push, Voice) and that's about it. If you're someone who likes to tinker with detailed sound settings, you might find it limiting. The speakerphone functionality works fine for calls, but the microphone quality isn't anything special.
Also, while the cream color looks fantastic and distinctive, it does show dirt more easily than darker alternatives. Not a dealbreaker, but something to consider if you're planning serious outdoor adventures.
This speaker hits a sweet spot that's surprisingly rare: it's rugged enough for actual outdoor use, sounds good enough for serious listening, looks distinctive enough to spark conversations, and now it's priced competitively with much less capable alternatives.
If you've been waiting for a waterproof speaker that doesn't look like tactical gear, or if you're tired of choosing between durability and audio quality, the Emberton III at
I'm keeping mine permanently in my travel bag – it's become the one speaker I trust for everything from beach days to hotel room listening. At this price point, it's competing with speakers that can't match either its sound quality or its style, let alone both.
