Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL Partybox 310 is the better pick: it ranks #4 of 46 party speakers by sound quality (rated 4.5/5), against #43 (rated 2.2/5) for the Sony GTK-XB72. If you want one new, the JBL Partybox 330 replaces the JBL Partybox 310 and is rated 4.6/5 at $629.95.
The JBL Partybox 310 is the better-sounding, deeper-bass pick. Absolute deepest bass of any battery powered speaker, most balanced sound in the class, handle and wheels are convenient. Its bass reaches about 32Hz before falling 10dB, against 56Hz for the Sony GTK-XB72. It is rated IPX4, while the Sony GTK-XB72 has no water resistance. It has an adjustable EQ, which the Sony GTK-XB72 lacks.
The Sony GTK-XB72 is the lighter pick. Exceptional sound quality, powerful bass, vibrant multi-colored LED lights. At 26.9 lbs (12.2 kg) it weighs noticeably less than the JBL Partybox 310 at 37.5 lbs (17 kg). It supports LDAC Bluetooth, which the JBL Partybox 310 lacks. It links with other speakers (Partychain up to 100 speakers), which the JBL Partybox 310 cannot. The catch: No deep bass at all, weird midrange peak, rolled off treble and overall strange tuning.
Buy the JBL Partybox 310 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the JBL Partybox 330, which replaces the JBL Partybox 310.
