These are not really the same size class, and that is the honest framing here. The JBL Partybox 310 ranks #3 of 44 party speakers at $499.95; the Sony SRS-XV900 ranks #9 of 10 large party speakers at $900.
On the JBL Partybox 310 side: Absolute deepest bass of any battery powered speaker, most balanced sound in the class, handle and wheels are convenient. The tradeoff: Very large.
The case for the Sony SRS-XV900: Can get slightly louder than a Partybox 310. Handle and wheels are convenient. Set against that: Not as deep of bass and loses more bass at high volume compared to the Partybox 310 and every other speaker on this page.
One note: the JBL Partybox 310 is discontinued, but it still ranks #3 of 44 party speakers, ahead of most of what is still sold new, so it is worth considering used.
Buy the JBL Partybox 310 at $499.95 if you want a party speaker. Buy the Sony SRS-XV900 at $900 if you want a large party speaker instead.
