It is important to remember that JBL Charge 4 is most appropriate for indoor use as it is not omnidirectional. To get the most of it, you will need to locate the speaker in front of where you are seated. If you locate it elsewhere, the sound may not be very good.

Winner: JBL Charge 4.


Both the JBL Charge 4 and Megaboom 3 are waterproof, but you may need to let your JBL Charge 4 speaker air out if it gets wet to restore its full functionality. Both speakers are water-resistant up to three feet deep for about 30 minutes. This means that if you’re using the speaker outdoors and it starts to rain, you don’t have to interrupt the music to seek shelter.

In addition to being water-resistant, the Megaboom 3 is also dust-resistant and has a longer lifespan than the JBL Charge 4. It can also withstand harsh environmental conditions without risking damage.

If you want a portable speaker that is beautiful, long-lasting, and can withstand the elements, the Megaboom 3 is the perfect choice.

Winner: Megaboom 3

The app will also allow you to control the speaker’s power. You will enjoy the block party experience when using this amazing speaker.

When using Megaboom 3, it will be possible to connect up to 3 phones to the speaker and then, take turns playing music from each device. This will allow you to hold a block party where each person will play the music that most appeals to him.


If you are looking for a portable speaker that is light in weight and one that you can operate with one hand, Megaboom 3 will be your ideal choice. The speaker weighs 1.3 pounds and has a length of 7.2 inches.

JBL Charge 4 weighs 2.1 pounds and has an 8.7 inches length. Though it is bigger than its Megaboom 3 counterpart, you’ll be able to operate it using one hand.


The JBL Charge 4 is available in 10 different colors, including black, blue, grey, pink, teal, sand, white, and green. These colors are plain and unassuming, so if you’re looking for a speaker that will make you stand out, this may not be the best option.

In contrast, the Megaboom 3 is available in four colors: lagoon blue, sunset red, ultraviolet purple, and night black. These colors are more appealing and vibrant compared to the dull and unattractive colors offered by the JBL Charge 4. Additionally, there are indications that UE will be releasing new colors for the Megaboom 3 in the near future.

Phone Charging

One of the winning points when it comes to JBL Charge 4 speaker is the ability to charge up to 4 phones when listening to music. However, this will shorten the battery life of your speaker which will make the playtime shorter. If your phone battery is about to die and you’ll need to keep it on, the shorter play time will be worth the sacrifice.

Megaboom 3 does not have a charging feature and will not be of help if you need to remotely charge your phone. 


JBL Charge 4 is the more affordable portable speaker at $150. You will pay $200 for Megaboom 3 speaker which is $50 more. Your choice will depend on the budget you’ve set aside for your purchase and where you’ll be using the speaker. For instance, if you’ll use your speaker in outdoor places, you will need the more expensive Megaboom 3 speaker.

Whether you are alone or you are enjoying an outdoor family gathering, you will love the clarity of sound from a Megaboom 3 speaker. You’ll not have any trouble customizing the bass, treble or mid to your preferred level.

Both JBL Charge 4 and Megaboom 3 are waterproof but EU has gone a step further to make their brand dustproof as well. As you enjoy your outdoor gathering, you will not worry about the water or dust that comes into contact with your speaker.

Best Battery Life

If you are looking for a portable speaker that will allow long paly time, JBL Charge 4 will be a perfect fit. The speaker will last for 20 hours though this could be shorter depending on the volume. Charging your phone as you play will also shorten the life of your battery.

Shortest Recharging time

When looking for a portable speaker, the amount of time it takes to charge will also count especially if you travel a lot. Megaboom 3 has a shorter charging time at 2.5 hours compared to the 5.5 hours it’ll take to fully recharge JBL Charge 4.

Considering the pros and cons, and the highs and lows of these two amazing portable speakers, it is impossible to come up with a definite winner. Your budget, where and how you’ll be using your speaker, and the charging time, among other factors, will determine your choices.
