Short answer: the JBL Partybox 110 is the better current choice because it keeps the sound quality while adding app control, splash protection and a much easier form factor. It is slightly more neutral than the older Partybox 100, reaches 41Hz, includes a three-band EQ, and offers mic and guitar inputs in a 23.8 lbs (10.8 kg) cabinet. The JBL Partybox 300 is discontinued; its replacement is the JBL Partybox 330.
The Partybox 300 has crisp highs, punchy bass, an 18-hour claimed battery and more physical inputs, including RCA. But it is heavier at 35.3 lbs (16 kg), lacks an app and EQ, has no IP rating, and is discontinued. Its bass and maximum output do not provide a clear advantage over the newer option.
This is not a close call unless the 300’s RCA input or extra runtime is essential. The 110 is easier to transport, better protected and easier to tune.
Buy the JBL Partybox 110 if you want a current, splash-resistant party speaker with app EQ and mic or guitar support.
Buy the JBL Partybox 300 if you specifically need RCA inputs and find a well-priced used unit in excellent condition.
Battery life favors the JBL Partybox 300: rated for 18 hours against 12 hours for the JBL Partybox 110.
If water resistance matters to you, the JBL Partybox 110 at IPX4 (splashing) holds up far better than the JBL Partybox 300 at no water resistance.
