The Harman Kardon Onyx Studio 9 Portable Stereo Bluetooth Home Speaker (Black) is a premium portable wireless speaker that combines stunning design with powerful, room-filling sound. Featuring Harman Kardon’s signature acoustic engineering, it delivers superior audio clarity, deep bass, and a wider soundstage through dual full-range drivers and a dedicated subwoofer, all tuned for balanced, detailed playback across music genres, movies, and podcasts. The sleek, iconic cylindrical shape with a premium fabric finish and anodized aluminum handle makes it a stylish centerpiece for any room, while the built-in rechargeable battery offers up to 8 hours of playtime for true portability—perfect for indoor use, garden parties, picnics, or moving between spaces.

The Onyx Studio 9 supports Bluetooth 5.2 for stable, long-range wireless streaming from phones, tablets, or laptops, with multi-speaker connection via the Harman Kardon One app—pair two Onyx Studio 9 speakers for stereo separation or connect with other compatible Harman Kardon speakers for even bigger sound. The app also enables self-tuning (automatic room calibration that optimizes EQ based on your environment), custom EQ adjustments, firmware updates, and control of lighting effects on the speaker’s subtle LED ring.

Its IPX7 waterproof rating allows worry-free use near pools, at the beach, or in the rain (submersible up to 1 meter for 30 minutes), while the durable build withstands splashes, dust, and everyday handling. Dual passive radiators enhance bass response without distortion at high volumes, and the speaker automatically adjusts output for optimal clarity whether placed on a table, shelf, or floor.

The Harman Kardon One app provides intuitive control, letting you group speakers, adjust sound profiles (bass boost, vocal enhancement, or balanced), and manage playback across multiple devices. The Onyx Studio 9 also supports voice assistant integration (via connected phone) and simple top-panel controls for play/pause, track skip, volume, and Bluetooth pairing.

Whether you’re hosting gatherings, relaxing at home, enjoying outdoor moments, or elevating your workspace audio, the Harman Kardon Onyx Studio 9 offers exceptional sound quality, elegant design, long battery life, and smart connectivity in one versatile package.
