[This review was collected as part of a promotion.] The JBL Xtreme 4 is a great speaker for taking to the beach or a picnic, or to just chill in the yard. The shoulder strap makes it a cinch to carry to wherever you are going. The fact that it is waterproof it makes it a great beachside companion. The sound is amazing it has great bass and highs, and on top of that you can take your phone far from it and it still be connected. Also I love the ability to have up to 3 devices connected at once, add in the fact that it has a built in phone charger makes it a very versatile device. One downside is I wish that it came with some kind of protective case.

[This review was collected as part of a promotion.] Packaging Packaging Packaging Buy it for the joy of listening, but also for the packaging. Packaging is making the world a better place! This package flows with the mind! It’s an aesthetic and engineering marvel! Nominate that packaging person for president! Whatever you’re paying them, double it! The unsung hero we all need! This speaker sounds as good as it looks on the package… bumping bass, great in an open air environment or it can fill a garage or barn with the benefit of portability via a handy shoulder strap. Slightly on the heavy side, however this thing is built to take a tumble. Don’t be shy, use it, abuse it and enjoy the 24hr charge life! So buy it, unpack it, pack it back up and unpack it again! Then your ears can do the rest.

[This review was collected as part of a promotion.] I don’t usually run around town with these kinds of speakers, but I feel with the strap this one is a win, either while riding a bicycle or just hanging out at the park or in the backyard. I was very impressed with the packaging and the folding handles built into packaging were genius. Unboxing it, I was pleasantly surprised with a full size charging block and not just a simple usb-c cable. Now onto how it sounds. Most times Bluetooth speakers over-emphasis bass, this one does not! It’s quite impressive how well composed the sound is and the ability to control and modify 5 bands of eq in the app is awesome. Flat curve was pretty good but a small bit of tweaking and you can dial it right in. Overall very happy with the smooth playback despite it being over a Bluetooth signal.

[This review was collected as part of a promotion.] I got this speaker to use whenever and wherever I need a great sounding portable speaker. I chose this one because of its looks and the claims from JBL that it’s water proof, dust proof, has a replaceable high capacity battery, and sounds amazing with AI Sound Boost. I’m not sure what AI Sound Boost is but it must work because it really does sound amazing! Smooth deep bass, clear midrange, and bright crispy treble. It really is tough too. The first day I had it it fell off the tailgate of my truck and you can’t even tell! I think my only complaint isn’t with the speaker, it’s with the JBL Portable app. I wish it allowed connecting other types of speakers on Bluetooth to play at the same time. Not that many people can afford 2 JBL Extremes. As far as the speaker goes, A+, ⭐️⭐️⭐️⭐️⭐️, 👍! Good job JBL!

[This review was collected as part of a promotion.] A portable speaker with an amazing sound! At the time of reviewing this, it’s not in the app, the sound is very clear and the bass booms! The battery is amazing and having it IP67 is a wonderful bonus for out door events! I highly recommend

[This review was collected as part of a promotion.] The Xtreme 4 speaker has been an absolutely stellar bluetooth speaker. I have been using it in my apartment and the sound quality phenomenal - particularly when it comes to hosting parties. I will defintely be taking this speaker with me out to the beach and on my boat. One characteristic about I particularly love about the speaker is that we're able to connect MULTIPLE speakers at ONCE. This was great for when I was playing music both in the living room and my bedroom and did not have to move my speakers or replay the song using another speaker. 10/10 would recommend

If you love music then this product is highly recommended. The jbl extreme 4 is a small compact sound system like nothing I have heard before . The sound and quality of the product is honestly beyond my expectations. It's waterproof easily transported from area to area or place to place. , easy to give it a quick recharge when needed and it easily connects up to your phone to play your favourite songs through. The style of the jbl extreme 4 is smart. It looks smart and has a place anywhere in the house without looking untidy. The sound is one of the best I've ever heard ,the quality , the clearness and the beats are fantastic. If you are a music fan this product will do everything you expect and more. It also has a carry strap that you can use to carry it inside or outside the house. Great for a get together , picnics , bbqs etc. Also good as you can take it around the house to use without the hassle of moving heavy equipment around. You can have good quality music wherever you go ! This product way went above and beyond what I thought it could do from the first opening of the box. What an absolute pleasure this product is.

[This review was collected as part of a promotion.] Great speaker. Clear sound. Connected easily and quickly straight out of the box. The highs and mids really came thru. The ability to personize the equailizer with the JBL portable app is a fantastic feature for those with particular tatses. Not the most bass heavy speaker, but it has plenty and did well for me. The speaker is big and feels very solid and rugged without being too heavy. The carry strap and the clips feel very sturdy and would give me confidence to carry anywhere. This speaker has plenty of sound for its size and can used inside or out.

[This review was collected as part of a promotion.] First thing first let’s appreciate the detail and build quality of this beautiful powerful speaker. Unboxing this beast is always top notch with the beautiful packaging known from JBL. It comes with a usb type C AC charging cord. Instruction manual and a pretty nice looking adjustable carrying strap. After giving this speaker a full charge which didn’t take long. Before unplugging it. I tested it plugged in to AC power for an added boost in sound. From playing hip hop to rock and more fast paced EDM the Xtreme played it nice and clear and didn’t distort when I turned it up. Bass was solid and the passive bass radiators were moving some air. This thing gets loud even when I went portable and took it out to the park. The wide carrying strap made it easy to walk around or when I saw a nice tree branch I looped it on there with no problem and did a quick workout. Also it’s IP67 so it can handle the Xtreme elements outside especially here in Texas. Another cool and I think is a first for the Xtreme is they added a removable battery to extend the life even more since all batteries lose charge over time. Just knowing I can buy a new battery and bring it back to life again is a major selling point for me. Also with the JBL portable app which I used for different types of music I play. It has 4 to choose from and a custom EQ to customize to your liking. Also has a feature to boost the battery called Playtime boost. It pretty much turns off most of the bass to extend playtime. Would be cool if the speaker had a button on it to activate it or even a button on top for the EQ. But overall I really loved the Xtreme 4 and I’m sure you will too!

[This review was collected as part of a promotion.] I received the JBL Extreme 4 a few weeks ago and so far it is performing great. The audio is top notch JBL quality we have to expect over the years. Bass notes are unbelievably deep from such a small enclosure! This thing thumps! Extreme 4 arrived will packaged as most of their products,setup was super easy and quick. My android phone was supplying the music in less than a few minutes. One bit about the JBL App... The JBL Portable App works well. I will say JBL needs to spend a little more time on the app development.JBL has a few apps and they only work with certain products they have. I wish they had one app that could control all their speakers! Its a pain to start 1 app and then find out it can't connect because its the wrong app! Something that bugs me is once you're playing a song,you cant adjust the equalizer on the fly! You can't add treble or bass while listening. One other quirk,when you increase the volume past the phone's high volume limit, the speaker cuts out for a second... Back to the Extreme... Really great sound! The bass hits hard and the highs are quite sharp. Really emphasizes the bass. The midrange voices seem to pop out of nowhere! We took the speaker out on a few walks and its form-factor is really comfortable. JBL includes a high quality shoulder strap that puts the speaker in a great position in the small of your back to comfortably carry and listen to it while walking. Although the speaker appears a little large or heavy to walk with,its really not! We were very pleased. While we were out one day,it started to drizzle and I didn't freak out as the speaker is waterproof. The rain didn't affect the audio quality at all. I have a JBL Clip,an older JBL Flip 4 and now this speaker. If there will be more than myself listening, definitely the Extreme 4 is coming along! Its great at the backyard BBQ,the tennis court, even time out on the boat or beach because its waterproof! Nothing bad I can say about the build quality or the audio of the Extreme 4,just wish the app was a little more useful.
