If you guys want bigger sound with heavy bass then JBL Xtreme 2 could be the best choice. Don’t make the purchase decision without our honest JBL Xtreme 2 review. So, without ado, let’s jump into JBL Xtreme 2 review.

Physical features

In simple words, these are the significant improvements from the first generation extreme that you need to know.

  • Upgrade the transducer driver
  • Audio power 250 watt
  • Much stronger base
  • JBL connect plus features
  • It is x7 waterproof
  • Two 3d passive radiators in both side
  • Carrying strap

Going over the physical features first this is a very decent size 9 inches wide, 5 inches tall, 4.8 inches deep. All while weighing in at 4.7 pounds making this slightly bigger and just slightly heavier than the other two heavyweights the UE mega boom and the Bose Soundlink 3.

Now although bigger and heavier, it’s still mobile. Just not as easy in someone’s bag. JBL does include a simple carrying strap attach this to both sides of the speaker for over the shoulder carrying. But being big and heavy isn’t such a negative trait if you’re looking for big sound.


You can see this on either side with the massive here base radiators when music is being pushed. But before getting it to sound the top features your very sturdy, very tactile Bluetooth pairing button, volume down, power on and off and to the right is what they call the JBL Connect feature.

You can change other newer JBL speakers like another extreme, the flip 3 or the soon-to-be-released pulse 2 and have those basically play at the same time from this same source offering more room-filling music or have music in different parts of the house.


Volume up is to follow with less the pause and play button. Now rest assured here everything on the extreme is rock solid from my testing. No flexing. Metal frames seams are tightly assembled and materials all around look top-notch but besides being built tough. It’s also rain and splash proof with very rugged and tough nylon braided like exterior.

Underwater submerge test

You just can’t submerge this underwater. So no dropping this into the lake or into the pool either intentionally or accidentally. Unlike the UE mega boom, I tested a few months back that however can be immersed into water up to one meter for up to 30 minutes. Of course, the Bose Soundlink 3 can’t get one at all.

Fully waterproof


Finally while the extreme west splash-proof the new extreme 2 is going to be fully waterproof. The JBL extreme 2 could handle light rain and light splashes of water but the extreme 2 can be immersed in up to 1 meter of water for 30 minutes.

However, it’s been reported that you cannot hear the music play when it’s in water because it will always turn itself in the direction to play the music downwards into the water unlike the boombox which plays the music upwards these are the other features of the extreme 2. It comes with two metal hooks just like the first generation extreme a carrying strap that uses the metal hooks it also has a bottle opener included on the strap making it convenient to open bottles at parties

Physical connections


Now I’m going to the bottom of the extreme. Just enough white rubber feet are provided to prevent the speaker from shaking off the table and behind this orange zipper here or all of your physical connections. Now I do have to admit this is a bit tight to the very first time trying to connect the wires.

But after the second or third time and then realizing, pressing the upper flap was actually key. To the left is a micro USB port for servicing only I tried charging this with a USB cable that didn’t work. A 3 and 1/2 millimeter input, 2 USB ports to charge two devices simultaneously such as your smartphone Android, Tablets just to keep the music going and playing and less to the right are the power ports for the supplied wall charger.

Battery life

Indeed this has a large charging brick for a Bluetooth speaker but inside is a massive 10,000 milliamp battery. The extreme claims it can be powered for up to 15 hours and with my personal testing the same test that I do on all my Bluetooth speakers leaving this playing at 50% volume as a middle-of-the-road standardized test. The extreme lasted me a crazy 18 hours and 16 minutes to be precise soo until it basically shut off on me.

And when compared to the UE mega boom although it’s claimed to have 20 hours my same test yielded 17 hours and 30 minutes of on time regardless. Both of these speakers does ridiculously well in battery performance compared to what’s out there.


Now in regards to recharging JBL claims three-and-a-half hours I was able to achieve from a dead battery to full in 3 hours and 20 minutes.

Missing features

So that’s everything physical wise about the extreme here. I do admit it is missing NFC or near field communication for easy pairing feature that I think is really underrated but highly convenient for Android users.

Sound quality

Overall sound quality on the JBL extreme 2 definitely is better than that. On the JBL extreme the treble on the extreme – is not as harsh as not on the JBL extreme. The meets also better get slightly better meds and then the bass is not as boosted as the dot on the JBL extreme.

Come into overall loudness it’s a different story entirely. Honestly not easy I was kind of surprised about the JBL extreme 2. It’s not as loud as the JBL extreme. If you ask me. Yes! And at max volumes, it sounded kind of very soft. the bass seems to disappear and it’s kind of very soft are well on the extreme. It loses bass at max volume.


Now one last thing before doing the sound test there is a built-in speakerphone option JBL claims to offer noise and echo canceling technology.

Transducer driver

The transducer driver has been upgraded, the audio power which was 40 watts in the JBL Xtreme has been upgraded to 50 watts. In the extreme 2 so it is said to be louder than the extreme. The passive radiators are now 3d passive radiators. Passive radiators helped produce a deeper sound from the woofers so that you get good base even from small-sized speakers.


They have shuffled around the sizes of the drivers to hear a little bit. Now we have 17-millimeter drivers in the JBL extreme 2 comparables to the 63-millimeter drivers that we had in the JBL extreme and we had 35-millimeter tweeters in the JBL extreme and they have downscaled that to 20-millimeter tweeters in the JBL extreme 2.

Frequency response rating

Now the next thing that is probably affected by the changes in the drivers is the frequency of response rating. Now we only had 70 Hertz lowest rated on the JBL extreme but now the lowest rating on the frequency curve on the JBL extreme 2 is 55 Hertz which is good. Don’t get me wrong that is really good at least when it at 70 but I honestly was hoping for something a little bit lower than that.

On something like maybe 20 Hertz or at least 40 Hertz, at least 40 Hertz I mean Sony is doing that with the x-term speed speakers the XP 40, the XP 41, the XP 31, they can all go as well as 20 Hertz not as loud like you can barely hear it. But it is there and I was hoping for something like that for the speaker this big a new wasted version.

I don’t know why JBL could not go at least lower than 55 but disappointed but I’m happy that at least they went lower than the extreme and talking about frequency response maybe this is a good time that we get a sound sample of these two speakers.

Louder stereo music experience

The new 3d design performed better and it is set to produce more bass than the extreme. The Xtreme had the JBL connect technology to link it to one other speaker. And also with JBL connect to amplify the sound and have a louder stereo music experience.

Connect plus features

The JBL extreme 2 comes with JBL connect plus which gives you the option to link it with over a hundred speakers. Note that it can only be linked to speakers also with Connect plus which includes other extreme tools boomboxes pulse threes and flip fours.

Bluetooth technology

JBL extreme two is slightly heavier than the JBL extreme by about half a pound and they updated from Bluetooth 4.1 on the JBL extreme to Bluetooth 4.2. I was hoping for something like 5.0 as far as the Bluetooth version but we’re still rocking 4.2 or more speakers. I’m not sure why because it’s been out for quite some time now but Bluetooth manufacturers or makers are still running 4.2 at the most.

JBL Xtreme 2 New Firmware Update

The JBL extreme 2 has been on the market for a little over a few months now and even though I do like the extreme overall. A lot of people complain that it just doesn’t get loud enough. But now JBL has released a new firmware update that does considerably improve the extreme choose performance.

If you’ve been on the fence about getting the extreme 2 or if you really have one, let’s see what this new firmware updates all about.

I actually didn’t hear about the new firmware update for the extreme until I actually saw comments mentioning it in another article. Unlike the plus 3, there’s really no need to even open up the JBL connect the app with the extreme but when you do open up the app. You’ll see a little notification and you can start downloading the firmware update right over-the-air.

The only thing you really need to do is just have the extreme 2 plugged in and wait for about 10 minutes or so.

Impact on the sound signature for new Firmware Update

Like I said in the in this review the extreme 2 hands-on nature sound signature that overall sounds better than the original extreme. And after the firmware update, the extreme to still has the same sound signature but I have noticed there is considerably more bass overall. There’s more bass at lower volumes and more bass at higher volumes. But the biggest changes are new from our update brings is how loud the extreme 2 actually gets.

Now, these next clips have each of the speakers playing the same section of a song and next volume. On battery power alone you will clearly see the original extreme struggles to get over the hundred db mark. But it has an easier time when it actually plugged in whereas the extreme 2 has no problem staying over the 100 db mark after the new former update.

On battery power alone the extreme 2 is now clearly louder than the original extreme even when its plugged in. And for comparison before the firmware update the extreme to perform pretty similarly to the original extreme.

It only occasionally managed to break through that hundred db mark. But even at these how our volumes the JBL extreme 2 still manages to keep distortion to a minimum when the original extreme is playing a max volume it does start to sound bright and space starts to sound muddy.

Whereas the bass on the extreme 2 is cleaner and resonates much smoother. But even though these former l theatres great at all there is some give-and-take regarding battery life.

At 80% volume the extreme 2 is now averaging 9 hours of playback time or as before it was getting 10 hours but all things considered I don’t think it’s that big of a deal even that you’re getting more bass and however volume out of the extreme 2.

Should you buy JBL Xtreme 2?

If you already have a JBL Xtreme, you don’t need to upgrade soon. Anyway, it’s up to you. It is your decision whether you want to buy it or not. But we recommend it to buy if you are using UE Wanderboom or similar. JBL Xtreme 2 has different selling point, different view. If you are a party lover, if your living place is bigger, if you want to feel Bass then JBL Xtreme 2 is for you
