Lots of branded headsets do one thing very well, and that's sell the brand that makes them rather prominent on the side of your head. Jabra's Halo isn't of that breed, as the branding on this headband-style Bluetooth headset is small and inoffensive. The headband folds down on itself, and this serves a dual-purpose. Firstly, and most obviously, it serves to make the headset a lot more portable, especially as a small velcro lipped pouch is supplied with the Halo. Secondly, it's how you actually turn the Halo on. When it's clicked out in headband form, it switches on and attempts to pair with nearby compatible mobile phones and Bluetooth devices.
Inside the Halo's box is also a slim usage guide, a micro USB cable for charging and a micro USB to 3.5mm adapter for connecting the headset up to devices that lack Bluetooth compatibility. Quite why you'd buy an expensive Bluetooth headset for the purposes of not using Bluetooth eludes us slightly, but it's not as though the cable costs extra.
As few buttons as possible seems to be the mantra of recent Bluetooth devices we've tested here at CNET.com.au, and the Halo isn't bucking the trend here. There's really only one button, used for call answering duties that sits alongside a touch-sensitive panel. This is used for volume control on all paired devices, as well as play/pause and track skipping duties, but only on Bluetooth devices that support the AVRCP (Audio Video Remote Control Profile) standard. Some phones do, and some don't. iPhone users, be warned — you're in the latter category.
Charging and pairing up the Halo was, like many Bluetooth devices, a simple enough affair. The Halo can be paired with up to two Bluetooth devices, although it won't stream audio from both simultaneously. The click to open power function works smoothly and quite obviously. That's where the good news sort of ends for the Halo, however.
