Excerpt: The unit offers high quality sound. You can crank up volume with no distortion - a far cry / improvement over other products found within this category.
I like the unit's high-tech functionality and ease of use - the ability to connect the OnBeat directly into my TV is a nice value add.
Summary: It's time to junk your old portable CD and MP3 Players and go Bluetooth. This JBL RUMBLE is a fantastic piece of audio technology with rich bass, clear mids and highs. There is a dedicated down firing sub woofer on this system which really adds oomph.
