Core numbers

Up to 16 hours of battery life

The built-in battery provides up to 16 hours of playback on a single charge. Because it uses USB power, you can top up from a power bank or laptop during longer days out. So you avoid interruptions when you are away from mains sockets. In practice, this keeps the music going from morning through to evening.

True Wireless Stereo pairing for wider coverage

True Wireless Stereo (TWS) lets you pair two compatible Soundcore speakers for a broader soundstage. This is useful when you want to fill a larger patio or campsite without increasing volume to distortion levels. Because the connection is wireless, setup is quick and tidy. So you can scale your audio to suit the space.

IP68 waterproof and dustproof build

The IP68 rating means the speaker is fully protected against dust and can be submerged in water. It handles rain, splashes and beach conditions without worry. Because the exterior is sealed, you can rinse off sand or mud after use. So you get reliable performance in unpredictable UK weather.

Integrated carry hook for secure placement

A built-in hook lets you hang the speaker from a tent loop, rucksack or pergola. This keeps the driver at ear level and reduces vibrations from surfaces. Because it stays off the ground, you avoid splashes and dirt. So your setup stays neat wherever you set up.

USB Type-C charging with included cable

The speaker charges via a modern USB Type-C port. A USB Type-C to USB Type-C cable is included for convenience. Because it uses a standard connector, you can share chargers with other devices. So you pack fewer cables on trips.

Hands-free calling via your phone

While the speaker has no built-in microphone, it supports hands-free mode through your phone. This lets you take calls using your device’s mic without touching it. Because the audio plays through the speaker, you hear callers clearly outdoors. So you stay connected while your phone stays safe.
