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 driver unit is the component that produces sound in the device. Bigger drivers are more powerful and can produce better bass.
A speaker driver is an individual transducer that converts electrical energy to sound waves. More drivers may result in better sound quality.

Devialet Silver Phantom Gold
2 x 2250W
Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
An amplifier is integrated into the device. An audio amplifier takes a small signal and makes it bigger without making any other changes in it which results in better sound, so any sound source can be connected to speakers.
A passive radiator looks like a normal driver (speaker) from the front, but on the backside all of its 'guts' are removed. Passive radiators allow woofers to produce deep tones that otherwise may not have been possible. They can have the same sonic output as larger speaker cabinets, but in a much smaller size.
This type of device allows you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise. Ideal for plane rides and morning commutes.
More microphones result in better sound quality and enable the device to filter out background noise.
