Marshall Launches Stockwell III in Singapore with 40+ Hours of Battery and a Serious Upgrade After 7 Years

Marshall has finally refreshed the Stockwell, and it’s been worth the wait. Seven years after the Stockwell II arrived, the Stockwell III lands in Singapore with a big jump in battery life, better acoustic hardware, and tougher weatherproofing – all wrapped in that unmistakable Marshall amp-inspired design.

Marshall Stockwell III

The headline upgrade here is battery life – the Stockwell III now runs for over 40 hours on a single charge, which is double what the Stockwell II offered. That’s enough to run through about 800 songs without stopping to top up. When you do need a charge, 20 minutes with a 30W USB-C PD charger gives you 8 hours of play.

Sound-wise, it uses three drivers: a 3-inch woofer and two 1.75-inch wide-band drivers – arranged for 360° stereo coverage. Marshall calls this True Stereophonic, which means there’s no “dead side” wherever you’re standing. A Dynamic Loudness feature automatically adjusts bass and treble balance at lower volumes so things don’t sound thin when you’re playing it quietly.

It also doubles as a power bank via USB-C, handy if your phone is dying mid-session. The IP55 rating (up from IPX4 on the Stockwell II) means it handles both dust and water jets from any direction – suitable for outdoor use beyond just accidental splashes. Design-wise, it keeps the classic Marshall look: leather carry strap, top-mounted control dials, metal grille with the Marshall logo. Available in Black and Brass or Cream.

Emberton III Gets New Colours

At the same time, the Emberton III (S$299) is getting two new colourways – Vintage Black and Black & Silver if you want something more compact at a lower price point.

Where to Buy

The Marshall Stockwell III is now available in Singapore for S$379 at TC Acoustic. Both the Stockwell III and the updated Emberton III colourways are available now at tcacoustic.asia and the TC Acoustic Store at The Adelphi.
