Harman Kardon Onyx Studio 9 - Wireless Bluetooth Speaker

Room-Filling Sound Wrapped in an Iconic Design

The Harman Kardon Onyx Studio 9 turns any room into a listening room. A three-channel speaker system paired with Constant Sound Field technology widens the soundstage well beyond the speaker's footprint, delivering clear vocals and dynamic tones that surround you rather than project from a single point. Self-tuning technology automatically calibrates output to the space it's in, so the sound stays balanced whether you're in a small bedroom or an open living area.

The signature circular silhouette pairs an aluminum frame with durable fabric, giving the speaker double duty as a striking centerpiece and a sturdy carry handle. Bluetooth 5.3 connects up to two devices at once for easy playlist swapping, and Auracast lets you link multiple Onyx Studio 9 units together for synchronized, multi-room sound — all controllable through the Harman Kardon One app.

A built-in rechargeable battery delivers up to 8 hours of continuous playtime, and a USB-C port doubles as a charging point for your phone while the music plays, making the Onyx Studio 9 as practical for everyday use as it is for hosting.
