The Jawbone JAMBOX is an incredible piece of engineering. It fits in your hand and has a wonderful rubber exterior that makes you feel confident that it can stand up to the rigors of life and come out unscathed. It’s sound quality is stunning and very reminiscent of the BOSE Wave sound system. The base is deep and full. If you place your hand on the surface that the JAMBOX is sitting on, you can feel the base. Mid and high tones are crisp and clear. Jawbone were very smart to keep the very loud 85 dB within a reasonable range to avoid distortion. This is one of the most exciting products we have reviewed this year. Audiophiles everywhere playing music on mobile phones and Bluetooth capable MP3 players +can enjoy phenomenal sound quality on the road without wires.
