A speaker driver is an individual transducer that converts electrical energy to sound waves. More drivers may result in better sound quality.
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.
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
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.
