With the iPhone Bluetooth Headseat, incoming calls to the Apple iPhone can be received wirelessly. The compact device weighs only 6.5 grammes, has a body made of anodised aluminium and looks like a small black rod with a glossy surface crossed by fine lines. The rounded earpiece connects seamlessly to the body. The attractive combination of square and circle creates a dynamic effect, which remains until the earpiece is inserted in the ear, leaving only the straight part of the headset still visible. The simplicity of form is continued in the operating concept: a single button on the top of the device provides access to all functions. It is slightly convex, discreetly located and blends into the overall clear look of the device. The headset has an integrated lithium-ion battery delivering up to 5.5 hours of talk time and up to 72 hours of standby time.
