JBL Charge 4 vs. UE Boom 3: Not a Fair Fight (With One Exception)

After weeks of testing, I determined JBL Charge 4 is the best option for most people because of its superior sound quality and battery life. UE Boom 3 has crisp and omnidirectional sound with the best design on the market, but it lacks the depth and richness of Charge.

I’ll compare and contrast these two portable speakers (JBL Charge 4 vs. UE Boom 3) while evaluating five categories: sound, design, durability, power, and software.

JBL Charge 4

  • Sound: It has the best sound of any speaker this size, with better bass, volume, and richness than Boom 3.
  • Design: There are 10 colors, but they’re boring.
  • Durability: It’s waterproof but needs to be aired out if it gets wet.
  • Power: 8 hours at 60% and 6.5 hours at 85% volume. It works as a portable phone charger.
  • Software: The app isn’t good, but it’s not necessary because there’s no equalizer or other settings.

Best for you if...

You want the best sound for a small speaker and an extra two hours of battery (60% volume). It has fantastic one-directional sound, but it isn’t terrible outside either. There’s no wireless charging, but you can charge your phone with its battery.

Budget Option:

Charge 3 sounds similar to Charge 4 and is the best value of any speaker on the market.

UE Boom 3

  • Sound: The sound is crisp, clear and omnidirectional, but tinny compared to Charge 4 with relatively no bass.
  • Design: Every one of Boom 2’s flaws was fixed. It’s a brilliant design.
  • Durability: It’s waterproof and dustproof and more durable than Charge 4.
  • Power: 6 hours at 60% and 3.5 hours at 85% volume. You can charge wirelessly.
  • Software: The app lets you play with the equalizer, preload playlists, and control the power.

Best for you if...

You want an ultra-portable speaker with a crisp sound that's fit for outdoor use and don't care about bass, volume or battery life. Boom 3 is a fantastic balance of aesthetics and practically, and you can wirelessly charge with their $40 charging dock.

Upgrade Option:

Megaboom 3 is only an extra $50 and sounds exponentially better than Boom 3 (my review).

I made a deals tracker that compares today's price to Amazon's 60-day average. When you use my Amazon links, it supports my site and lets me provide free and unbiased content.


Why listen to me?

  1. I’ve been obsessed with gadgets since I was eight years old.
  2. I bought each device with MY money.
  3. I’ll update this post frequently because my opinions change.
  4. I don’t have insider access. I’m just like you, the everyman.

charge 3 vs boom 2

JBL Charge 4


Sound (A-):

  • The sound is outstanding for its size and price. Compared to UE Boom 3, it has a better bass and is much richer and louder. Charge 4’s sound is closer to Megaboom 3 than Boom 3. Overall, it’s a brilliant-sounding speaker and provides fantastic value at $150.
  • You need to be in front of the speaker for optimal listening. Although it’ll be fine outdoors, it’s not ideal because it’s not omnidirectional.
  • How does the sound compare to Charge 3?
    • Charge 4 has one driver with 30W of power, while Charge 3 had two drivers with 10W of power. I prefer two drivers, but overall you get more power with Charge 4, and you can hear this in the bass.
    • Charge 4’s treble sounds better.
    • Overall, the sound doesn’t differ much, and both offer great sound for this price and size.

Design (B-):

  • It weighs 2.1 pounds and is 8.7 inches long. It’s still small enough that it can be held in one hand.
  • It looks not the best looking, but at least it has a base to sit on (relative to Flip 4).
  • It comes in 10 different colors (Black, Blue, Forest Green, Grey, Pink, Red, Sand, Teal, and White). The amount of color options is a departure from how JBL typically operates, but the colors plain and not overly appealing.
  • The port cover is perfect. It stays latched (for waterproofing), but it’s easy to open. This is something that Flip 4 could learn from its big brother.
  • You can plug in your old school devices because there’s a 3.5mm port.

Durability (B+):

  • Like UE’s lineup, it’s entirely waterproof (IPX7 rating). It can be submerged in water for up to 30 minutes.
  • While it’s waterproof, you have to let it air out if it gets wet because the water gets in between the radiators on the sides and makes the sound muffled.
  • It’ll float just like Boom 3.

Power (A+):

  • The battery is impressive for its size and loudness delivered. It’s rated for 20 hours of playback and takes four hours to recharge. My real world tests:
    • 8.5 hours with 60% volume.
    • 6.5 hours with 85% volume.
  • It works as a portable phone charger with its 7,500-mAh battery USB port.
  • Charge 4 charges with USB-C, which is a great upgrade.

Software (D+):

  • It uses Bluetooth 4.2 and you can have two devices paired at once. While this is a  downgrade from the three devices simultaneously pair with Charge 3, it’s a good move to improve connection stability.
  • The JBL app is worthless and doesn’t provide any value (assuming you can get the app to pair with Charge 4). Charge 4 is a new product you should expect them to update fix it the pairing, but mine wouldn’t pair at the time of this review. The good news is that you don’t need to bother with the app.
  • The Bluetooth range is about 15 feet further and the connection seems more reliable.
  • You can connect it with other JBL Connect+ (Charge 3, Flip 4, Xtreme 2) speakers, but pairing can be shaky because it cuts in and out.

UE Boom 3


Sound (C-):

  • It has two drivers and two passive radiators.
  • While listening to Boom 3 alone, I don’t hate it, but when I play it side by side with Charge 4, Boom 3 sounds a bit like a tin can.
  • There’s more bass than JBL Flip 4, but there’s no match when compared to Charge 4.
  • UE Boom 3’s biggest advantage is that it delivers 360° sound, which makes it a better option for outdoor use and large gatherings.
  • There are four preset equalizer options, but you can customize the bass, mids, and treble to any level.

Design (A+):

  • It weighs 1.3 pounds and is 7.2 inches tall. It’s noticeably smaller and lighter than Charge 4, but this isn’t a dealbreaker.
  • There are four colors (Lagoon Blue, Nightblack, Sunset Red, Ultraviolet Purple), but there are more set to be released in the future. The Ultimate Ears colors with their two-toned fabric are more visually interesting than the boring colors of JBL.
  • Boom 2’s design was great, but there were three major issues which were all fixed with Boom 3:
    • The charging port was on the bottom, making it difficult to charge and listen simultaneously. Now, the port has been moved to the side or it can be charged wirelessly with the base.
    • You had to use gestures by picking up the speaker and hitting it sideways to pause and skip songs, now there’s a “Magic Button” to do play, pause and skip.
    • There was an ugly rubber strip down the middle. Now it’s gone and features a more minimalistic design. Everything about the design looks phenomenal!
  • There’s no 3.5mm port.
  • To find out the battery life, hit the “+” and “-” at the same time for a verbal callout of the volume percentage.

Durability (A+):

  • It has the same waterproof rating, but it’s also dustproof.
  • It feels more durable than Charge 4 because the radiators aren’t exposed. Either way, each brand will be able to withstand a drop.
  • It will float to the top of the water.

Power (B):

  • UE lists a playback time of 15 hours, but this is not a reasonable figure because they must’ve tested at unreasonably low volumes. My real world tests:
    • 6 hours with 60% volume.
    • 3.5 hours with 85% volume.
  • The playback time isn’t as good as Charge 4, but it’s almost worth it because of UE’s wireless charging. It’s an eye-opening experience. While UE’s charging base is an extra $40, it’s worth every penny. It’s awesome to have your speaker run off power while in the house, then when you’re ready to leave it’s at 100% battery. It takes the thinking out of power management.

Software (A-):

  • Ultimate Ears simplified things and made one app for all Megaboom and Boom speakers. It’s a brilliant app.
  • With “Block Party,” you can connect three phones to one speaker, and three people take turns playing music.
  • With “Party Up,” you can pair up to 150 UE speakers together and make them play duplicate sound or create a stereo pair. This works well sometimes, but I wouldn’t count on it. Like anything that relies on Bluetooth for multiple connections, it can be shaky.
  • Like Charge 4, it uses Bluetooth 4.2, and you can have it paired with two devices at once. The curious thing is that the Bluetooth range is listed at 150 feet, but in reality, the range is the worse than Charge 4 (30 feet listed).
  • The firmware is updated frequently. It’s great that UE is continually improving the product and didn’t call it quits after the release.
  • You can power it on and off via the app.
  • Lots of people don’t like the “power on sounds” of portable speakers. UE lets you turn those off, while JBL doesn’t.
  • There’s isn’t a button to activate your phone’s assistant (i.e., Google) because there’s no mic. This means no speakerphone either, but these are worthwhile sacrifices from last year’s version.
  • You can preload four Apple Music playlists and have them play by holding the Magic Button for two seconds. The music plays, and you don’t touch your phone.

    Hey, I am trying to pick a speaker for my family and I. We have it down to 3 options UE Boom 3, UE Megaboom 3 and the Charge 4/3. We like to host and have a pool, the music we listen too really varies from hip hop, and rock all the way to jazz and pop. We need a loudspeaker that works best for all types of music. Can you help me choose a speaker?
