Functions of the 300 vs. 310
The first thing that stands out when you take a closer look at the two speakers: There are more buttons on the top of the new [url="https://www.amazon.de/dp/B08FB2PFLV?tag=sebmil-21",name="JBL Partybox 310",title=""] to control bass and other features.
Unlike the [url="https://www.amazon.de/dp/B07HJK5WCG?tag=sebmil-21 ",name="JBL PartyBox 300",title=""], the light effects on the 310 can now be controlled via an associated app. The stethoscope effects no longer flash inside the speaker but on the outside of the rim and can be turned off.
The battery life of the two models is the same; both last 18 hours according to the manufacturer. On the other hand, the JBL PartyBox 310 can be recharged much faster. Instead of 5 hours, it now only takes 3.5 hours until the battery is full again.
Sound of the 300 vs. 310
JBL has changed the sound only slightly in the jump from the 300 to the 310. The speakers for the treble have gotten slightly larger (0.25 inches), which translates into a crisper sound. In terms of maximum volume, JBL has made gains, and the 310 has three decibels more to offer. [topdeals]
Transporting the party boxes
The outwardly most impressive difference between the two party boxes is of course that the newer version has two wheels on the bottom. On the top, a handle can be extended like on a rolling suitcase. For transport, this is of course a clear advantage over the predecessor model, which could only be carried by a loop on the top.
The fact that the JBL PartyBox 310 is a bit heavier at 17.41 kg than the predecessor, which weighed 15.8 kg, is not a big issue.
Dimensions of the 300 vs. 310
Not much has changed in terms of size. The 300 measures 31 x 32 x 69 cm, the 310 variant 32.5 x 36.78 x 68.7 cm.
There is an improvement in terms of robustness when it comes to protection against water. The JBL PartyBox 300 was also protected against splashing water according to the manufacturer, but the JBL 310 now has the IPX4 seal, so it is officially safe against "all-sided splashing water".
Party box 300:
Conclusion on the comparison of the JBL Partybox 300 vs. Partybox 310
There are minimal improvements in the sound of the JBL Partybox 310 compared to its predecessor. Instead, there are more buttons on the top to regulate the sound, and the light show can be controlled via an app.
A big plus compared to the older model is the shorter charging time. Instead of after 5 hours, the box is now fully charged after 3.5 hours.
Literally the most weighty advantage of the 310 over the 300 are the wheels for better transport, which compensate for the slightly increased weight of the new box. Especially for people who are often on the road at festivals, it is therefore worth updating from the JBL Partybox 300 to the JBL Partybox 310.
