While it is not as portable as perhaps a headset, XtremeMac Tango Studio iPod Speakers weigh just over 1.5 kilograms and take up a space measuring only 16.5 centimetres in height, less than 30 centimetres in width, and under 10 centimetres in depth. Since it is not a large unit, some may find it lacking in the bass range, particularly at a distance. It is also lacking radio presets, although the next model in the line includes this feature for an additional £40 or so.
