Jabra's M5390 multi-use headset certainly couldn't be accused of coming sans peripherals. Compared to many other Bluetooth headset kits, it's practically overloaded. First there's the rather large earpiece, which can optionally be worn with a supplied overhead headband for comfort. That plugs into a base station that recharges the headset as well as acting as the communication hub for the headset's other functions. You also get a small (and arguably pretty easily lost) USB key for PC softphone use. There's little doubt that this is a headset aimed pretty squarely at the corporate market, and only peripherally at the market that wants a Bluetooth headset to wear out and about. The sheer size of the headset means that practically anybody wearing it outside will feel rather self conscious, and in our tests one of our testers commented angrily that it made them recall working in a call centre many years ago.
The Bluetooth side of the headset will pair with any Bluetooth 1.1 compliant device, but that's not all that exciting. For a whole lot less than the AU$275 asking price of the M5390 you could get that. What the M5390 does is pair with multiple communication devices within an office environment. It'll pair with up to two Bluetooth-capable mobile phones simultaneously. It'll also pair with a desk phone via standard RJ11 connection, and finally with a range of PC-based softphone clients, including Skype. The basic idea here is that it's the one headset that you use with all your phones. There's one minor omission here for those looking for a complete solution, and it's that you'll still have to lift your desk phone handset to make calls.
