Marshall Emberton III Review: What a Bluetooth Speaker

Design & Build Quality

At first glance, the Emberton III stands out with its iconic Marshall script logo and classic grille design.

Key design highlights:

• IP67 dust and water resistance, making it adventure-friendly
• Soft-touch silicone exterior that feels premium
• Intuitive multi-directional control knob for volume, track skipping, and play/pause

Weighing around 700 grams, it strikes a perfect balance between portability and solid build quality.

Sound Performance

This is where the Emberton III truly shines. With Marshall’s True Stereophonic technology, the speaker delivers a surprisingly immersive 360-degree sound.

What we loved:

• Powerful bass without overwhelming the mids
• Crisp, clear vocals — great for rock, pop, and even podcasts
• Loud enough to fill a medium-sized room or a backyard gathering

Even at max volume, distortion is minimal, which is rare for a speaker in this size category.

Battery Life & Connectivity

The Emberton III offers up to 30 hours of playtime on a single charge — a huge plus for long trips or parties.

Charging highlights:

• USB-C fast charging
• 20 minutes of charging gives you about 4 hours of playtime

Connectivity:

• Bluetooth 5.1 ensures stable and quick pairing
• No auxiliary port, which may disappoint some traditionalists
