The JBL PartyBox 300 is a large, tall speaker with eye-catching circular RGB lights. You can place it either horizontally or vertically, as its tweeters adjust to create a stereo image based on its positioning. This speaker has a long 18.3-hour battery life and can get very loud. It's lacking a lot of low-bass, but it has a Bass Boost feature. Also, the microphone and guitar ports make it suitable for musicians.
The JBL PartyBox 300 is decent for music. It has a balanced mid-range and should reproduce vocals and lead instruments clearly.

It has a very imposing design, and it'll be noticed thanks to the circular RGB lights. This speaker can be placed either horizontally or vertically, as its tweeters adjust to stereo in both positions.
This speaker has sub-par portability. It's very tall and heavy, which may be inconvenient if you plan to move the speaker frequently or use it in multiple locations. On the upside, it has a handle to make it easier to carry, and it doesn't require a wired power source to work. If you want a more portable speaker for parties, check out the Bose S1 Pro System or the Bose S1 Pro+.
This speaker has an acceptable build quality. It's mostly made of plastic with a metal grille on the front side, and these materials make the speaker feel solid, durable, and well-built.

You can connect an external microphone and guitar to the mic and guitar inputs on the speaker's rear, and you can control their volumes using their dedicated volume knobs.
