Know before you buy
The Kilburn III features True Stereophonic 360° sound, which is designed to project audio in all directions. This makes it highly effective for filling outdoor areas with consistent, well-rounded sound rather than just focusing it in one direction.
Yes, the speaker includes a 3.5 mm auxiliary input. You can connect wired devices like older MP3 players, turntables, or laptops directly to the speaker using a standard aux cable.
An IP54 rating means the speaker is protected against limited dust ingress and water splashes from any direction. While it is durable enough for poolside use or dusty trails, it should not be submerged in water.
The top-mounted knobs allow you to manually adjust the bass and treble levels to suit your personal preference or the acoustics of the room. This gives you more control over the sound profile than speakers that rely solely on digital presets.
Yes, the Kilburn III features a built-in power bank function. You can connect your mobile device to the speaker to top up its battery while you continue to play music.
A full charge takes approximately 3 hours. Once charged, you get over 50 hours of playtime, making it one of the longer-lasting portable speakers in its class.
