Summary: The JBL On Tour iBT Bluetooth speaker is a solidly constructed speaker and a great fit for those that aren’t looking for a very portable option. Its four drivers allow for a strong, well-balanced sound, but it doesn’t focus heavily on the bass. The battery life is around six hours, depending on how it is used.
Pros: The large four drivers produce a well-balanced and rich sound.
Cons: The Bluetooth speaker is missing some useful additions, such as a remote and a speaker cover.
Excerpt: On Tour iBT and Zephyr 550 have a number of features in common. They both use Bluetooth to make nearly instantaneous connections with your iPhone, iPad, or iPod touch, streaming stereo audio from speakers mounted behind perforated grilles. Each has a microphone built in that allows users to make and receive phone/FaceTime calls, as well as integrated volume and phone call buttons, plus ports for power, auxiliary audio-in, and—unusually—USB.
