Using AI Sound Boost, the Xtreme 4 can maximize its already impressive sonic capabilities. AI Sound Boost analyzes the incoming audio signal in real-time, while simultaneously using an AI algorithm to predict the loudspeaker movement and power response. The result is the ability to push the drivers to their maximum capability, fully exploiting dynamic range, maximizing volume and bass, while minimizing distortion.

If your phone or tablet is running low on power, you can use the massive 9444 mAh LiPo battery as a power bank to recharge your device. Simply plug it into the Xtreme 4 via the USB-C port.

If the large soundstage of the Xtreme 4's JBL Pro Sound is somehow not enough, you have the option of pairing it to a second Xtreme 4 speaker for bigger, stereo sound. You can also wirelessly connect the Xtreme 4 to other PartyBoost or Auracast-enabled speakers in order to share music across a wide array of available speakers.

The JBL Portable app lets you update the Xtreme 4's firmware, unlock new features, access product support, and the built-in EQ. Make custom EQ adjustments or select from one of the EQ presets.

With an eye on sustainability, JBL partially constructed the Xtreme 4 from recycled materials, and packaged it in FSC-certified paper that's printed with soy ink.

Q: 1. If you need to reformat the disk to use with a Mac does it still auto-backup from the SD slot (and not re-copy files copied over previously)?

A: Sorry, I have not tried that. Set mine up for Mac when I bought it. Auto backup from SD card works as advertised. I format SD cards after backing up to two devices so I don't ever see files re-copied.

A: It has at 5400 rpm drive. Its not a speed demon but great back-up drive for the price. Only drive this size that I know of with a 7200 rpm drive is the G-Force. Pricey but IMO worth the money not only for the speed but also the reliabilty.
