Interestingly, unlike most wireless stereo headsets on the market, this one is also supplied with a cable so it can be used with non-Bluetooth enabled MP3 players. Unfortunately, when you plug in this cable all Bluetooth functionality is lost. So you can't, for example, use a wired connection to your MP3 player while still keeping the headset connected to your phone via Bluetooth. This is a real shame, but seeing as most other manufacturers do not offer any wired support at all we can't be too harsh on Jabra here.
You charge the headset via a microUSB connector that's found at the bottom of the right-hand ear piece. Jabra includes a USB wall charger in the box, or alternatively you can charge it via your PC or laptop. It takes around two hours to fully charge and while it's on charge an LED on the inside of the headphone band glows red and then turns off to show you when it's full of juice. From a full charge you'll get around eight hours of music playback from it or eight hours of talk time, or a mixture of the two. In our test, we got around seven hours use from it for mostly music listening and a bit of talking on our mobile.
There are plenty of things to like about the Halo. The folding design makes it easy to carry around, the call quality is first class and battery life isn't bad either. However, the problems with stuttering audio when used with our laptop and PC, plus the lacklustre bass response stop us from giving it wholehearted praise.
