The XG300 is the biggest of the bunch, measuring about 12.5-inches by 5.4-inches by 5.4-inches, and weighing in at a little over six and a half pounds. Sony says it’s the most powerful of the three, using a combo of Front Tweeter and “MEGA BASS” features for deeper basses and clearer high-frequency sounds. It’s also the longest-lasting, claiming up to 25 hours of play time on a full charge. Whereas the XE300 and XE200 are both smaller and lighter, though they focus more on evenly-distributing audio in a space rather than raw power and don’t hold a charge for quite as long. The XE200, in particular, is the smallest option at about 3.5-inches by 8-inches by 3.7 inches and a little under two pounds, with a 16-hour battery life. The XE300 sits between the two extremes at 4.1-inches by 9.4-inches by 4.7-inches, and weighing just under three pounds, with an in-use battery life of about 24 hours. All three of Sony’s new portable speakers are available for preorder today and will be shipping/available for purchase on July 12th. They’re priced at $349.99 for the XG300, $199.99 for the XE300, and $129.99 for the XE200.
