Jawbone JAMBOX 2.0 Firmware Update Offers Better Sound, Extended Battery Life
Updates for the JAMBOX include more crisp and clear phone calls, a Silent Mode in case you need to disable voices and notification sounds, and support for the Jawbone Companion for Android.

The BIG JAMBOX also enjoys the new Silent Mode as well as better audio streaming with fewer dropouts once you put distance between the source and the speaker, improved battery life for both the speaker (up to two more hours) and paired devices, and the ability to control volume from either the paired device or the speaker.
Note that the BIG JAMBOX requires a device running iOS 6.1 or later to take advantage of the better audio features and battery life.

If you’ve been eyeing a JAMBOX, now is a great time to splurge; for what we assume is a limited time, you can save $50 on either of the two JAMBOX models and still get the new firmware update.
