Volume is the quantity of three-dimensional space enclosed by the product's chassis or, in simpler terms, the space the product occupies.
There is a control panel on the device body, so you can easily access the volume control or remote without having to interact with a cable or another device it's connected to.
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
The device is dustproof and water-resistant. Water-resistant devices can resist the penetration of water, such as powerful water jets, but not being submerged into water.
Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. They also have more bass and clear high notes.
When covered under the manufacturer’s warranty it is possible to get a replacement in the case of a malfunction.
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.
A remote control allows you to control the device remotely. The remote control can be included or optional.
The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability.
