Other notable features include compatibility with Bluetooth 2.1+EDR, as well as A2DP stereo audio, HFP 1.5, and HSP 1.1. The Bluetooth connection is multipoint, allowing you to connect two devices at the same time. Also included are a 3-foot stereo aux cable for connecting non-Bluetooth devices, two Micro-USB cables (1-foot and 5-foot), a form-fitted case, and a USB wall socket adapter.
The Bluetooth range of the Jambox is an expected 30 to 40 feet, depending on obstructions in the room. Sonically, the Jambox is a mixed bag. Its sound is undeniably impressive for its size, but not great overall, and certainly not for its price. Aliph uses a pair of proprietary 1.25-inch drivers on the front of the Jambox, along with a rear-facing passive radiator woofer on the back, responsible for its surprisingly present low-end punch. When you turn it on, it even gives a little subfrequency kick just to show off.
A larger Bluetooth speaker, such as the Creative D100 or D200, will easily outgun the Jambox for much less money, but lack the Jambox's speakerphone capabilities and custom features--not to mention its more compact size.
During testing, we paired the Jambox effortlessly with an iPad, iPhone 4, and iPod Touch. Once paired, the Jambox emits a little tone to signal the established connection, and you're off and running. While routing sound to the Jambox for video playback and games, we noticed no obvious audio latency.
Incoming call quality was very good using an iPhone 4 as the paired device. Outgoing voice quality using the Jambox's integrated microphone was decent when placed within arm's reach, and free from the background hiss associated with cheap speakerphone units. Name recognition during voice calling mode also worked well.
Aliph rates the battery life of the Jawbone Jambox between 8 and 10 hours, depending on volume levels. During our informal testing, we were impressed by how well the speaker maintained its charge in standby mode. It's also worth noting that Jambox uses a quick-charge technology, bringing the battery level near 80 percent after 90 minutes of charging and reaching full charge in 2.5 hours.
