JBL Partybox 300 VS 310 (Comparison)
Our pick: The JBL PartyBox 310
While both speakers sound great and have a similar roster of specs, the 310 is the newer, more updated version of the 300 and has a better control system on its top. For about $50 bucks extra, we'll take the updated 310 and the improved controls.

We're comparing two versions of the JBL PartyBox: The 300 and the 310.
These are both a type of standalone powered speaker meant for things like playing music, watching movies, or doing karaoke, either via indoor or outdoor venues. They're fairly large, weighing in around 35-40 pounds but are also meant to be highlight mobile.
They even provide mic and guitar inputs.
This page takes the two speakers and compares them side by side, going over some specs and basic grading.

Grading
While both speakers sound incredibly good and full, covering the same frequency response, we like the control setup for the 310 a lot better than the 300. The 310 also has a better connectivity profile with 1/8" jacks instead of RCA jacks.

What's it good for?
Both the 310 and 300 are designed to be larger, portable speakers for indoor and outdoor gatherings where any kind of audio projection is required. This could include speaking, listening to music, watching movies, or even something like karaoke as we mentioned earlier.
There is no difference in the job description of the two speakers, as both are used primarily for the aforementioned purposes.
Main Spec Differences
The 310 uses two 2.5" tweeters while the 300 uses three 2.25" tweeters. The 310 mirrors the subwoofer configuration of the 300 with two 6.5" woofers, one stacked on top of the other. We also see a movement away from RCA connections in the 310, in favor of 1/8" aux ins and outs.

The JBL 300 VS the 310. What are the differences?
Summary of Comparison
While there are more subtle technical differences between these two speakers, we like the 310 better simply because it's more updated, has a better control system, and better connectivity profile.
It's also not dramatically more expensive than the 300, which makes us more okay with spending the extra money to get the more recent, more up-to-date speaker.
If you just want the cheaper option, the PartyBox 300 is certainly adequate and doesn't lack any crucial features.
But in a vacuum, the 310 is just nicer.
We'd recommend it in most scenarios.
