Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. They also have more bass and clear high notes.
We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability.
The height represents the vertical dimension of the product. We consider a smaller height better because it assures easy maneuverability.
The device comes with its own special case or pouch, which is useful for safe transportation.
We consider a thinner chassis better because it makes the product more compact and portable. Thinness is a feature highlighted by many manufacturers of mobile devices, but it is essential for a wide range of products.
