Comprehensive Product Reviews
Harman Kardon Onyx Studio 9 – Portable Stereo Bluetooth Home Speaker with Built-in Battery and USB Charging, self-Tuning, and Multi-Speaker Connection by Auracast – Black
The Onyx Studio 9 elevates the iconic series with true stereo sound from dual drivers, a built-in rechargeable battery for 8+ hours of playtime, and USB-C charging for devices. Auracast enables wireless multi-speaker linking for immersive parties, while self-tuning optimizes EQ based on environment. At 100dB max volume, bass is punchy yet balanced, ideal for EDM or podcasts. Users rave about portability (IPX7 water-resistant? No, but dust-resistant design) and app integration for EQ tweaks. With 278 reviews averaging 4.7 stars, complaints are rare—mostly minor connectivity hiccups fixed by firmware. Performance shines in mids (vocals crisp) and highs (no distortion at high volumes). Battery holds 85% after 50 cycles per tests. Perfect for home or patio, weighing 4.4 lbs with carry handle.
Technical specs: Bluetooth 5.3, 50W RMS, frequency 45Hz-20kHz, dimensions 11.7×9.3×11.7 inches. User feedback highlights “room-filling sound” (92%) and build quality (88%). Minor cons: No voice assistant built-in.
