JBL Xtreme 2 vs. UE Megaboom 3: Do You Want Sound or Portability?

Updated 11/18/2018

After a month of testing, I determined UE Megaboom 3 is the best of these two portable speakers because of its omnidirectional sound, portability, wireless charging and durability. JBL Xtreme 2 is louder with better sound all-around, but its design doesn’t make sense.

I’ll compare and contrast these two portable speakers (JBL Xtreme 2 vs. UE Megaboom 3) by evaluating five categories: sound, design, durability, power, and software.

UE Megaboom 3

  • Sound: It’s not as loud as Xtreme 2, but it’s loud enough with a crisp, clear sound and equalizer options.
  • Design: The two-tone mesh fabric looks fantastic. It weighs half of Xtreme 2.
  • Durability: It’s shockproof, dustproof, and waterproof for 30 minutes.
  • Power: 10 hours at 60% and 5 hours at 85% volume. It can wirelessly charge.
  • Software: The app is great. You can control the music and power the device.

Best for you if...

You want great portability and the best-looking speaker on the market. Megaboom 3 is portable, loud enough for outdoor use and parties, and you can wirelessly charge. At higher volumes, the bass gets boomy and the battery runtime is weak, but it sounds excellent when it’s not side-by-side with Xtreme 2.

JBL Xtreme 2

  • Sound: It’s louder with a better bass than Megaboom 3, but the bass sounds funky when listening from the side.
  • Design: It’s heavy and bulky, making it difficult to carry, but it comes with a strap.
  • Durability: It's waterproof but not as durable as Megaboom 3.
  • Power: 13 hours at 60% and 8 hours at 85% volume. You can charge your phone.
  • Software: The app blows and there’s no equalizer, but the Bluetooth range is better.

Best for you if...

You want deep bass and high volume and don't care about portability. It sounds better than Megaboom 3 when you're standing directly in front of it. It'd be a great stationery home speaker. But if that's what you're after, why not get a wired WiFi speaker? Speakers like Sonos One have superior sound for a lower price.

jbl xtreme vs ue megaboom

UE Megaboom 3


Sound (A-):

  • Megaboom 3 offers excellent omnidirectional sound. It’s crisp and loud from all directions (whether you’re sitting in front, behind or to the side). This makes it ideal for outdoor use or parties.
  • The sound is balanced and sharp with the solid level of bass at standard volumes. The bass gets boomy and overpowering at higher volumes.
  • It can’t get as loud as JBL Xtreme 2.
  • You can edit the sound with the app’s equalizer. There are four presets, and two are helpful. The “Voices” preset works well for podcasts and “Cramped Spaces” works well for small rooms. Usually, it’s not worth your time to toggle with their EQ.
  • Bottom Line: If you don’t hear these two speakers side by side, you’ll love Megaboom 3. It sounds fantastic, is plenty loud, and was my favorite sounding Bluetooth speaker before I tried JBL Xtreme 2. JBL Xtreme 2’s sound beats Megaboom 3 handily, but its form factor doesn’t make sense.

Design (A+):

  • It weighs two pounds, is 8.9 inches tall, and sits vertically. It’s half the weight of JBL Xtreme 2, making it more portable.
  • The two-tone color combinations and materials are more attractive than Xtreme. UE typically releases new colors a few times a year too. They currently have Lagoon Blue, Nightblack, Sunset Red, Ultraviolet Purple, and Urban Magenta. It’s the best-designed speaker on the market.
  • There were design problems with the original Megaboom:
    • There weren’t play, pause or skip buttons. To skip a song, you had to tap, which only worked with the speaker in your hands. With Megaboom 3, you can use the Magic Button located on the top for these commands.
    • The charge port was on the bottom so that you couldn’t charge and listen at the same time. Now with Megaboom 3, the charge port is on the side and if you buy the optional base, you can wirelessly charge.
  • There are two huge volume buttons on the side. You can press them simultaneously to hear how much battery is left.

Durability (A+):

  • It can take a beating and be just fine. It’s shockproof and dustproof.
  • It can be submerged in a meter of water for up to 30 minutes. And it’ll float back to the top if you drop it.

Power (A-):

  • The listed playback time for Megaboom 3 is 20 hours and takes four hours to recharge. My real world tests yielded these results:
    • 10 hours with 60% volume.
    • 5 hours with 85% volume.
  • For an additional $40, you can wirelessly charge Megaboom 3 with UE’s base. Wireless charging for a portable speaker is a game changer.

Software (A):

  • The UE app is superior to JBL’s.
  • There are four preset equalizer options.
  • You can connect eight devices, with two connected at once.
  • With “Block Party” eight different phones can control the music in the queue.
  • The app and the speaker’s firmware are updated frequently, which is always a good sign.
  • You can connect up to 150 UE speakers at once and get them to play the same music. This doesn’t work perfectly due to Bluetooth’s limitations, but it’s not terrible. You can make them a stereo pair or go in party mode.
  • If you hold the Magic Button for two seconds, it’ll play music from your pre-selected playlists on Apple Music without using your phone. This is a cool feature, and I’d like to see it expand to Spotify.
  • Megaboom 3’s Bluetooth range is listed as 150 feet, but I got more range with JBL Xtreme 2.

JBL Xtreme 2


Sound (A+):

  • JBL Xtreme 2 is the loudest portable speaker I’ve tested. The maximum volume on Megaboom 3 is the equivalent of 80% volume on Xtreme 2.
  • It sounds fantastic as high as 80% volume. Once you’re past that point, the highs get stretchy.
  • The overall sound is crisp. The bass is cleaner and more consistent than Megaboom 3.
  • As long as you’re in front of the speaker, the bass sounds fantastic, but if you’re listening off to the side, it sounds overdone and boomy. There’s no way to change the bass or other sound settings through the app.
  • You have to be in front of the speaker to get quality sound. Ideally, the speaker should be against a wall. If you’re on the side, you’ll notice distortion. Listening outside isn’t ideal.
  • It sounds like a louder version of Charge 4. I had a hard time telling the difference between the sound on Xtreme 2 and Sonos One while standing in front.
  • Bottom Line: JBL Xtreme 2 is louder and sounds better than Megaboom 3 in every way, but it’s ranked lower in this post because of its design. If you want JBL’s brilliant sound but want portability, Charge 4 is the size of Megaboom 3 and one of the best values in tech.

Design (D+):

  • It’s over five pounds and a foot long. It comes with a carrying strap, but it’s huge and not portable. The size isn’t practical for this type of speaker. It’s better for home use, but you’re better off going with a WiFi speaker, like Sonos One for $200 instead.
  • It sits horizontally with two feet.
  • The port cover is hard to open and not nearly as nice as Charge 4.
  • It only comes three ugly and boring colors: Midnight Black, Ocean Blue, and Forest Green.
  • There’s a 3.5mm port for external audio devices.
  • There are six LED lights to indicate how much battery is left.

Durability (C):

  • JBL Xtreme 1 was only splashproof, but Xtreme 2 is waterproof (IPX7) and can withstand up to 30 minutes in a meter of water.
  • It’s not as durable as UE speakers. That’s based on research rather than first-hand experience, but you can tell by looking at the side of the speaker where the bass radiators vibrate as music plays. It feels more fragile, and its extra weight means it’ll have greater impact if dropped.

Power (B):

  • JBL lists 15 hours of playback with a three-hour recharge time. They undersold their battery times compared to Ultimate Ears. Based on my real-world tests:
    • 13 hours with 60% volume.
    • 8 hours with 85% volume.
  • JBL Xtreme 2 works as a portable phone charger with its 10,000-mAh battery.
  • It doesn’t charge with USB-C, which would’ve been the logical move considering it’s the standard for new tech products. Instead, it uses a bulky 19V, old school AC adapter with a power brick. This isn’t practical for travel because it’s heavy and it’s not a standard cable (USB-C or Micro USB) that you’d be traveling with anyways.

Software (D):

  • You can keep two devices connected simultaneously.
  • JBL’s app is useless. It doesn’t even show you the battery percentage. An app isn’t necessary, so why build one if it adds nothing?
  • You can group (“Party” or “Stereo”) other JBL speakers without an app because of the dedicated “JBL Connect+” button. You hit the button on both devices, and they pair together. JBL Connect+ grouping still cuts out because Bluetooth isn’t great for these things, but it works much better than the original JBL Connect.
  • Previous generation speakers with “JBL Connect” can’t pair with new “JBL Connect+” speakers.
  • You’ll get an extra 20 feet of Bluetooth range compared to Megaboom 3.

    Hi, I was reading your review of the JBL extreme speaker and you said speaker was good for indoor use “But if that’s what you’re after, why not get a wired WiFi speaker? It’s a confusing product when speakers like, Sonos One, have superior sound for a lower price.” Can you recommend a wired speaker?

  • Yep says:

    So you’re reviewing a speaker … used for listening to music presumably… and the one with the better sound loses by a mile. What’re you getting from UE??

    • Cam Secore says:

      Where did I say it loses by a mile?

      I said if you want the best sound, go with Xtreme. I called it a great stationary home speaker.

      If you care about any design and portability to go along with good sound, Megaboom is more well-rounded. Where’d I mess up?

      • Eric says:

        You “messed up” by saying the JBL is great yet giving it 2 D scores and a C compared to the all A scores on the UE. The qualitative assessment is completely misaligned to the quantitative assessment.
        I agree entirely with Yep’s comment, I can’t understand how a speaker who’s primary function is to play music is rated second to the one that doesn’t produce as good sound. You should introduce a weighting system into your quantitative assessment.

        • Cam Secore says:

          The grades are weighted with sound being the main focus, hence why Xtreme got 3.5 stars and not 2. My problem with the speaker is that I don’t understand its purpose. While it sounds great, if you want a stationary speaker, you’ve got better options.

          Why do you guys care about an idiot blogger’s (me) grading system? My thoughts are honest and mine. Use my free information along with other research to help make the best purchase decision you can. Thanks for stopping by!

      • Abe says:

        The review helped me. I am looking for something to take on river trips and was settled on the Extreme 2. After reading this I am leaning toward the Megaboom or something else. Loudness was the number one determining factor but now I have some more perspective.

    • Johnny J says:

      And the sound is FAR superior to UE. Has twice the capability in the low ends. Deep bass not just loud.

  • Steve says:

    Great review and comparison, thanks.

    You have helped me decide on my purchase. Sound and volume are most important to me with portability, but not constantly moving and I’ll always able to access standard powerpoints, so I’ll be going the JBL. The longer battery life and ability to charge my phone off it is also important.

    Thanks for pointing out all the differences to make a personal choice. And I actually like that you state your preference and why.

  • Jason L says:

    Very helpful article, thanks. Which of these would you recommend primarily for backyard use, and maybe 1x per mo. for the beach? I have a large pool @ 36 ft from our patio. We have an outdoor speaker system, but for the past year the sound goes in and out & our rock speakers have stopped working entirely. To get new outdoor speakers & re-wire everything will cost over $3k. I might even consider buying two of whichever u recommend as it’d still be a lot cheaper than re-doing our outdoor system

    • Cam Secore says:

      You’d be good with either, but I guess I’d lean towards JBL Xtreme in your situation. It’s louder and you don’t need it to be portable.

  • Schermann says:

    Hi, I’m a senior industrial designer and I’m writing this while the JBL plays Spotify (Euge Groove) in the background. This speaker tied with ‘Wiseschematics RE Equaliser’ app allows you to maximise the deep bass response and stereo width, yes wide stereo. Megaboom is mono! The JBL is a two channel speaker allowing for rich spatial stereo separations. So if you want deep subsonics, wide spatialzed stereo with audiophile clarity at low, mid and high volumes, the xtreme2 is the pick.

    • Schermann says:

      The only negatives with the JBL is that it only has a shoulder strap and NO grab handle as such! And the passive side radiators are delicate and exposed to damage if touched!
      If it came with a clip on handle and caged end caps over the speakers to stop prying little fingers then there would be no contest here. Some things suggest that this can’t be thrown into a bag or trunk without serious damage occurring…

  • Ethan Morgan says:

    Is the megaboom loud enough to fill a large indoor room or for it to be heard outside space.

  • Schermann says:

    One thing I forgot to mention about the JBL is that on its internal battery power it is rated at 20W.
    Plug it into its AC power adaptor/charger and this doubles to 40W.

    Power 20W/40W in Stereo

    • Justin says:

      Forgive me if this is a stupid question, but does what you said mean the speaker doesn’t get as loud if I’m playing it at the beach vs. playing it in my home while it’s plugged in? If so, is this standard with JBL speakers? I just got the Charge 3, but I’m going to return it because it’s just not loud enough for a windy and choppy water day at the beach. I want something I can I leave on my beach chair, wade out into the water, and still hear it clearly.

      • Spence says:

        What Schermann said is correct. On battery power it’s 20 watts and plugged in it’s 40 watts. This means while plugged up it will be maybe 3-4 db louder than on battery. I own the Xtreme 2 and sound clarity is up there with the best like Denon and B&O speakers if you ask me. Loudness could be better but for your beach adventures I would go with the JBL Boombox. Sound signature/clarity won’t be the same but it easily gets louder than the Xtreme series and the bass is concert speaker equivalent.
