Needed a convenient portable speakers to my devices; Ipad and Xperia X Performance.
Chose XB2an because of its size, battery life of 12 hours and that it had Xtra Bass.
Two additional plus get it to the IPX is rated for water and dust, and it has the Speakerphone microphone when called.
In this price range; 700-800kr I found it hard to beat.
If the size was not important, I would have chosen XB3 as it has fatter bass and 24 hours of battery life!
