Sony SRS-XB501G review: specs and price

A speaker driver is an individual transducer that converts electrical energy to sound waves. More drivers may result in better sound quality.

Best

The driver unit is the component that produces sound in the device. Bigger drivers are more powerful and can produce better bass.

Best

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.

Best

For example

The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.

Best

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.

For example

A passive radiator is a type of driver (speaker) that doesn't have a voice coil and a magnet. The sound vibrations produced by a passive radiator depend on its mass and the size of its enclosure. It is usually used in combination with a woofer to produce deep bass tones.

For example

Devices with a subwoofer have a higher quality, deeper bass.

These microphones are designed to filter out background noise from the desired sound. Especially useful in noisy environments.

For example

The battery can be recharged and used over again.

An indicator shows you when the device has low battery.

The device's battery life (when in use) as given by the manufacturer. With a longer battery life you have to charge the device less often.

Best

How much power the device consumes when it's switched on.

Best

You can use the device with standard batteries instead of a power supply.

Best

802.11ac wireless works on the 5GHz frequency range. It offers higher transfer rates, improved reliability and improved power consumption. It provides advantages for gaming and HD video streaming.

For example

An auxiliary input allows you to play other audio sources by connecting them through a simple audio connection like a 3.5mm jack, i.e for MP3 or portable DVD/CD player.

For example
