Short answer: the Xtreme 3, and the ranking gap is large. It ranks #18 of 120 large speakers at $269.95; the XG300 ranks #82 at $199.99, $69.96 less. The Sony SRS-XG300 is discontinued; its replacement is the Sony ULT Field 5.
The XG300’s own cons are unusually long for a speaker marketed on sound. Bass that doesn’t reach as deep as competitors, an upper mids peak, a hollow character, rolled-off treble, and a volume that turns itself down automatically rather than holding steady, all while our notes call it overly expensive for what it delivers.
The Xtreme 3 has real flaws of its own, boosted bass and less balance than the best in its class, but it improved on the Xtreme 2 in both treble and bass extension, and our notes call it more balanced than the Xtreme 4 that eventually replaced it.
Buy the Xtreme 3 for the meaningfully better measured sound. Buy the XG300 only if LDAC codec support or its retractable handle are worth the tradeoffs to you.
There is a real battery-life gap here: the Sony SRS-XG300 is rated for 25 hours, the JBL Xtreme 3 only 15 hours.
