A speaker driver is an individual transducer that converts electrical energy to sound waves. More drivers may result in better sound quality.
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 driver unit is the component that produces sound in the device. Bigger drivers are more powerful and can produce better bass.
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.
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 height represents the vertical dimension of the product. We consider a smaller height better because it assures easy maneuverability.
The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability.
