Conclusion: JBL’s OnBeat Rumble delivered some of the deepest, most potent bass we’ve heard from a wireless speaker dock. It provides a clean and consistent Bluetooth connection, and a powerful sound that is sure to impress from the background of a party or at your next barbecue. However, we expect a lot from a $400 dock, and with the top end not delivering the goods once we turned a critical ear, it prevents the OnBeat Rumble from being classified as a slam-dunk speaker for pickier...
Pros: Rich, powerful bass, High velocity sound without distortion, Clean and clear wireless connection
Cons: Icy upper register, Lack of resolution in instrumental detail, Expensive
Excerpt: J BL’s OnBeat speaker dock may lack AirPlay audio streaming like its more advanced sibling OnAir, but it still provides plenty of ways to enjoy your tunes. There’s an iPod dock that also comfortably accommodates iPhones and iPads, plus a 3.5mm input on the back that caters for other types of audio player.
