These battery-powered bluetooth-enabled devices come with a meshed metal grille and a plastic body that is prone to scratches. You can place the speaker vertically or horizontally as per your need. This is possible due to its rubber feet on 3 sides.

You can handle and control the speaker with a power button for volume control, LCD display, play or pause music, and bass boost feature. These buttons are placed at the top of the speaker for your convenience.

There are three light buttons and music playback in this JBL Party box 300: Meter, Pulse, Party. Find your best mode and rock the party like a pro!

Coming to its build quality, its largely acceptable. You get a plastic body which is well-built, durable for long use and feels solid. However, mind you that these speakers are not waterproof so don’t plan your parties near water with this!

Audio Performance and Sound Quality

Its power input is its bass-boost outdoor mode with a frequency response range between 45Hz – 20kHz. The speaker body has a passive bass radiator so that you can adjust the EQ setting or enhance the bass.

Its audio input allows an amazing karaoke mode for all party lovers. The party speaker has instrument inputs and a microphone to help you gain control over the karaoke function.

You can play the battery-powered speaker at max volume without suffering any distortion in its balanced sound quality. Its mids and highs are clear and clean for the best quality louder sound.

So whether it is indoor mode or outdoor parties, this JBL speaker’s sonic performance never leaves you disappointed.

However, its soundstage performance is pretty mediocre. The output does not sound natural or wide as the soundstage is narrow and directional.

Connectivity Options

JBL Party box 300 has a USB input for a stable connection with your smartphone device and other JBL speakers. This USB feature enables JBL to score over Sony in this epic comparison.

You can pair up to 2 JBL speakers which works best when you want to switch between devices easily. However, due to latency issues, the performance may not be good for watching movies through your smart TV or phone.

Its connection versatility options range from analog inputs to Bluetooth-enabled devices to Aux, RCA, and 1/4-inch guitar and mic-input.

Its USB input supports WMA, MP3, and WAV music files.

You can even monitor its battery life using the lights above the power button.

But beware! This JBL speaker takes a while to charge so make sure its 100% loaded before the party begins!


This JBL Speaker is tall and heavy which makes it less portable. Better not use the speaker in multiple locations or use it frequently.

Talking about its positives, this JBL Speaker has a handle to make it easy to carry. Plus, it can work without a wired power source.

Advanced Features

Party box JBL speakers are known for their dazzling party lights to feature in their stereo mode. JBL Party box 300 has 3 in-built modes for party atmosphere: Meter, Pulse, and Party.

There is also a bass-boost button to create the chest-thumping effect and enhance bass-punch in louder sound output.

Its pairing button allows connection for up to 2 JBL karaoke speaker using the True Wireless Studio feature. JBL Music App can be used to adjust EQ settings.

This makes it worth its price range.

Who Is Partybox 300 For?

It’s ideal for musicians thanks to its guitar ports and a brilliant microphone.

Again, its balanced mid-range reproduces lead instruments and vocals clearly.

It can get very loud and with strong 18.3-hour battery life, this speaker is ideal for indoor and outdoor parties. However, it is water, dust, or impact-resistant so use it carefully outside your house.

You can use them to watch your favorite movies and youtube videos. You will not feel the deep rumble in action-packed scenes as its output lacks low bass and your real-world experience may vary when it comes to latency.

But the loud sound can seal your deal.

Along with this, you can also stream your favorite podcasts from your Bluetooth device (like phone or tablet) wirelessly to the bar, and it supports multi-device pairing.

I love listening to podcasts on the move, on the train, or as I do household chores. But this speaker is very big in size for such an experience. Again, it’s not compatible with Wi-Fi either.

Overall, you can enjoy multiple uses of these speakers but with limitations.

The extended frequency range gives the party freaks a chance to dance to the tunes of pop music!

The Bluetooth-enabled devices support mic audio input. It offers DSEE for stereo mode sound and ClearAudio+ for balanced sound quality and sonic performance.

Overall, these speakers are meant for party music and not for audiophile listening. This is mainly because the soundstage is very narrow and the instrument separation is not great at all!
