Marshall just solved a common problem: what to do with a perfectly good Bluetooth speaker when you want whole‑home audio, AirPlay, or Google Cast. The answer is the Heddon—a small, $300 streaming hub that plugs into select Marshall speakers and gives them Wi‑Fi, multi‑room capabilities, and even the ability to stream vinyl wirelessly around your house.

Instead of replacing your Acton III, Stanmore III, or Woburn III, you just add this box. It’s smart, cost‑effective, and very Marshall.

What the Heddon Actually Does

The Heddon is a dedicated streaming receiver. It connects to your home Wi‑Fi (or Ethernet, via the port on the back) and streams audio to your Marshall speaker using Auracast, a Bluetooth‑based broadcast technology. The speaker itself stays a dumb speaker—the Heddon handles all the networking and streaming smarts.

Key supported features:

Spotify Connect, Tidal, AirPlay, Google Cast – far more flexible than Bluetooth alone.

Multi‑room audio – add multiple Heddon units (or compatible speakers) and group them in the Marshall app.

Vinyl streaming – connect a turntable to the Heddon’s RCA stereo inputs, and the hub streams that analog signal to other Marshall speakers in your home. Note: your turntable needs a built‑in phono preamp, or you’ll need an external one.

Audio Quality: Hi‑Res DAC, But Not Lossless Over Air

Marshall says the Heddon contains a 24‑bit/192kHz DAC (digital‑to‑analog converter). That’s genuinely high‑resolution hardware. However, the wireless transmission uses the LC3 codec over Auracast. LC3 is efficient and sounds better than classic SBC Bluetooth, but it’s not lossless. Don’t expect to stream Tidal Max or Apple Music Lossless without some compression.

In practice, over a good Wi‑Fi network, the Heddon sounds cleaner and more stable than Bluetooth. The DAC handles the final analog output to your speaker, so the quality ceiling is high. For most listeners, the difference between LC3 and a truly lossless protocol will be subtle—especially on Marshall’s warm, rock‑tuned speakers.

Compatibility: Not Every Marshall Works

The Heddon is officially designed for Acton III, Stanmore III, and Woburn III. These are the current‑gen home speakers. You plug the Heddon into the speaker’s auxiliary input (3.5mm or RCA, depending on the model), and the speaker becomes a networked zone.

Older models can join the party, but with a wired connection only. Supported legacy models include:

Acton (I, II, Voice)

Stanmore (I, II, Voice)

Woburn (I, II)

Kilburn, Stockwell, Tufton (portable home speakers, not the small travel ones)

Not supported: Emberton, Willen, or any other ultra‑portable Bluetooth speaker. They lack the required input or are too small to benefit.

You can connect one legacy speaker via RCA to the Heddon and sync it with newer III‑series speakers in the same system.

Pricing & Launch Deals

The Heddon costs $300 on its own. Marshall is currently running two promotions (check regional availability):

50% off ($150) when you buy it together with an Acton III, Stanmore III, or Woburn III.

Free when you buy two or more of those speakers at once.

If you already own a III‑series speaker, the $300 price tag is steep. But if you’re building a new multi‑room system, the bundle deals make it much more attractive.

Who Is This For?

Marshall owners who want multi‑room – Instead of selling your $280 Acton III and buying a $400 Sonos Era 100. spend $150 (with bundle) to add Wi‑Fi streaming and grouping.

Vinyl lovers with multiple rooms – Stream your turntable to the kitchen, bedroom, or patio without running cables.

People who hate Bluetooth’s limitations – No more pairing, range issues, or audio lag. Wi‑Fi is rock solid.

Who Should Skip?

You only have one speaker – Just use Bluetooth or a $20 Chromecast Audio (if you can find one used). $300 is overkill.

You want lossless wireless – Look at Wi‑SA or dedicated multi‑room systems from Bluesound, Sonos (with their own speakers), or WiiM.

You own an Emberton or Willen – Heddon won’t work with them.

Bottom Line

Marshall’s Heddon is a niche but clever product. It’s not for everyone—$300 is real money for a streaming dongle. But if you’re already invested in the Marshall III‑series ecosystem, it turns your Bluetooth speakers into a modern, app‑controlled multi‑room system. The vinyl streaming feature is a nice bonus for analog fans.

Think of it as Marshall’s answer to Sonos Port or Bluesound Node, but built specifically for their own speakers. And with the half‑price bundle, it’s a much easier sell.
