Logitech has long had an eye for an attractive looking product and the Pure-Fi Mobile continues this trend. With a slim casing weighing just 460g, an attractive glossy black front fascia and silver accents surrounding its four speakers it is elegant and unfussy. That isn't to say it is simple, however, since inside the relatively small shell hides a virulent infection of technology
As the name suggests these are designed to be portable speakers. Including support for Bluetooth 2.0 EDR and its associated A2DP stereo audio profile, they can be paired with a music phone or capable MP3 player to stream music wirelessly. Most portable speakers might add a 3.5mm auxiliary jack and be done with it, but the Pure-Fi Mobile takes things a little further.
Naturally enough it does have a 3.5mm AUX jack, but it adds a mini-USB port. Using the provided cable you can connect the speakers to a PC, most likely a laptop in this instance, and they'll operate as a USB audio device. And, where many suffice with replaceable batteries, this set features integrated rechargeable Lithium-Ion batteries with a quoted continuous playback life of 12 hours.
As if this weren't enough you can also use the set as a speakerphone, as it features array microphones and call control buttons for answering calls when paired with a phone. Throw in the handy soft carry case and ability to charge over USB, a vital pre-requisite for any "mobile" device to our minds, and Logitech is already making a strong claim for the most comprehensive portable speakers available.
This belief is only enhanced when you take a closer look at the design. For example, the back is covered entirely in exceedingly grippy rubber, making the unit very easy to carry and thanks to a couple of rotating stands at either end the Pure-Fi is very stable, too. Buttons along the top of the device are logically lain out and clearly labelled and though there's a 'Source' button for selecting inputs, the device will automatically detect and switch to any newly inserted input.
Pairing is relatively straightforward, or as simple as Bluetooth allows, with no stupid finger contorting button combinations required to start the process - just hold down 'Source' for five seconds, enter the PIN number (0000) into your device and away you go. Bluetooth range will vary depending on your device, but the maximum range of 10 metres is more than enough.
