Vestlyd Stage A4 Bluetooth Speaker, Black (Each)

Stage A4

Portable Bluetooth active speaker with battery

The Vestlyd Stage A4 is a compact 2-way active speaker with a built-in battery: a 4-inch woofer and a 0.75-inch dome tweeter with neodymium motor are driven by a Class D amplifier delivering 40 watts total. Thanks to its aluminium front grille and rugged MDF cabinet with a carry recess, it's just as at home on the coffee table as on the terrace.

Long endurance

The built-in battery plays for up to 18 hours straight and is fully charged again in 2.5 hours. If you're in a hurry, the quick-charge function gives you enough power for another 3 hours of music in 20 minutes. You can check the charge level at any time on the front display.

Simple operation

You control volume and on/off via two grippy analogue dials on the back, plus there's a separate bass control to tailor the sound to the room or setting. It connects wirelessly via Bluetooth 5.0 with aptX HD – for wired sources there's also a 3.5 mm aux input and USB-C (charging cable included). Thanks to IPX2 protection, the Stage A4 shrugs off the occasional splash too.

Frequently asked questions

Is the Stage A4 waterproof?

It's splash-resistant to IPX2 and handles the occasional splash or light rain without issue. It won't survive prolonged rain or full submersion – but for an evening on a covered terrace or in the garden it's an excellent fit.

How long does the battery last?

Up to 18 hours at normal volume – usually enough for several days of everyday music. It's fully charged after 2.5 hours, and with the quick-charge function you can top up 3 hours of playtime in just 20 minutes.

Can I also connect the Stage A4 with a cable?

Yes. Besides Bluetooth 5.0 with aptX HD, there's a 3.5 mm aux input for CD players, TVs or other sources with a headphone jack. Charging is done separately via USB-C.
