Constant Sound Field technology is the centerpiece here — a three-channel system with a dedicated center channel for clear vocals, flanked by two specially designed tweeters, widens the soundstage so music feels like it surrounds you rather than coming from one direction. Self-Tuning means the speaker automatically calibrates its output to whatever room or space you set it down in, so sound quality stays consistent whether you move it from a living room to a patio.
Auracast support lets you sync multiple Harman Kardon speakers (or other Auracast-compatible speakers) together to fill a larger space, and you can also pair two Onyx Studio 9 units specifically for a boosted stereo effect. The integrated aluminum handle, made from 90% recycled aluminum, doubles as both a carrying handle and a stand, and the built-in battery delivers up to 8 hours of playtime — with a USB-C port that also charges your phone in a pinch. The Harman Kardon One App unlocks further EQ customization and lets you manage multiple connected speakers from one place.
