Inside the airtight enclosure are proprietary neodymium drivers and two opposing passive bass radiators along with a newly designed omnidirectional microphone, which is capable of 360-degree sound input with improved echo-cancellation and full duplex communication. The speaker also has LiveAudio "three-dimensional sound" technology built-in and updates to the speaker's driver system are handled through Jawbone's online interface. Connectivity is via a Bluetooth connection, headphone jack, or audio line out. Big Jambox can also connect to multiple devices at once, and users can control volume and play sequences from their device in addition to the speaker. A 2,600mAh rechargeable battery will provide roughly 15 hours of wireless listening time and 500 hours on standby. The Big Jambox speakerphone is intended for more of a conference room setting and while the Jambox has a front-facing microphone, intended to be used facing a user, Big Jambox sports a top-mounted omni-directional microphone to pick up sound from all angles. Big Jambox is rated as class one speakerphone.
