As part of the XB series, the Japanese giant Sony produces small entry-level and mid-level portable speakers that are equally suitable for the role of a kitchen speakerphone, a camping speaker or a club speaker. Most members of this family are equipped with proprietary X-Balance speakers, a waterproof case (note: most often IP67) and a capacious battery that can provide up to 24 hours of battery life.


Support for wireless pairing allows you to combine several Sony speakers, which can be combined into one orchestra with multi-channel sound. To connect a sound source, a wireless Bluetooth receiver of the latest version is usually used. For charging - USB C port. In the Sony Music Center mobile application, the user is free to change the sound settings using the equalizer, control playback or activate the Bass Boost mode. Many speakers in this series also support speakerphone functionality for hands-free calling.

Most of the current models of the XB series are made in a tube format a la JBL Flip with X-Balanced speakers, passive radiators, reliable moisture protection and a small strap with which the speaker can be attached to a backpack or hung on a tree branch while hiking. Also, as part of this series, Sony sometimes releases tiny and lightweight speakers a la the XB100, which in design and dimensions resemble smart speakers from Google and Apple. According to the manufacturer's idea, such little ones will work best as a portable speaker for a smartphone in the kitchen, outdoors, or on a hike, when you want to listen to music or a podcast at low volume.
