Product Details

Harman Kardon Onyx Studio Wireless Bluetooth Speaker with Rechargeable Battery

The powerful Onyx Studio reproduces music accurately with dual woofers and tweeters and two passive bass radiators, and streams music wirelessly from Bluetooth-enabled devices, such as smartphones and tablets.

Bluetooth: Stream Wireless Music, Internet Radio, and Podcasts
Bluetooth lets you stream wireless music from an enabled mobile device, leaving you free to mingle with guests, clean the house, or do yoga—all without interrupting the music. Moreover, Bluetooth plays your favorite songs over the system’s speakers, filling the room with richer sound than most smartphones, tablets, or laptops can.

Small Size, Big Sound
While compact speakers typically sacrifice bass response for portability, the Onyx Studio is equipped with two subwoofers and two passive bass radiators. This powerful combo fills any space with rich, resonant low notes that complement the crisp highs and help reproduce your favorite songs accurately.

Listen in Any Room
Designed as an audio solution for the entire home, the Onyx Studio is easy to carry between rooms so you can listen to music while working out, making dinner, or falling asleep. A built-in five-hour battery lets you use it away from the charger for long stretches of time, so you don’t have to worry about unplugging the speaker and plugging it back in every time you want to move.

Great set. Perfect sound with great bass depth. These are such a good deal. Was hoping to be able to run them in “stereo,” but won’t run them both from the same source at once. No problem, one has plenty of oomph.
