JBL Xtreme Portable Wireless Bluetooth Speaker – Performance

The JBL Xtreme Portable Wireless Bluetooth Speaker is created to suit the needs of consumers with regards to sound quality and bass performance.

The JBL Xtreme is a portable wireless speaker incorporated with 4 active transducers and 2 visible bass or passive radiators. From the build itself, you will already get the impression that the JBL Xtreme has great sound quality and strong bass. We tested this JBL speaker to prove whether it produces what many claims and found out that it really is!

For the sound quality, the JBL Xtreme produces clear, crisp, and full sound. Playing Ed Sheeran’s “Photograph” was really mesmerizing and satisfying due to the fact that the vocals coming from this JBL speaker is really deep and rich. The lows, mids, and highs are pretty impressive that it adds to the JBL Xtreme’s great sound quality. If the treble is already an excellent part in the JBL Xtreme’s sound quality, what’s more with its bass performance? Testing the bass performance of this portable wireless speaker made us realize that the JBL Xtreme is by far the best performing portable speaker, especially to its bass end. The bass is really strong thanks to its 2 built-in passive radiators. We would say that the JBL Xtreme has got some extreme bass performance. Even at higher volume, the bass delivers without creating any distortions. Really impressive.

How about its battery life? Another great feature for the JBL Xtreme is its battery. This JBL speaker contains a rechargeable 10,000mAh Li-ion battery that is rechargeable and powers up the JBL Xtreme Portablw Wireless Bluetooth Speaker for up to 15 hours of playtime. There is also dual USB port to charge this portable wireless speaker as well as charge other devices, such as your smartphone, just to keep the party going for a longer period of time.

JBL Xtreme Portable Wireless Bluetooth Speaker – Design

The JBL Xtreme is a portable wireless speaker that is also well-designed. I love how this cylindrical speaker looks like. It is simple yet eye-catching and very functional.

With dimensions of 4.9 x 11.1 x 4.8 inches and 4.7 pounds, this portable wireless speaker is possible to be brought outdoors or anywhere at any time. Although, we would actually say that the JBL Xtreme is somewhat heavy and that may be because of its build or contents such as its multiple transducers and radiators, but with its quality, it would be considerable and worth it. This portable wireless speaker is mainly made with metal, hard plastic, and woven fabric. It also has a strap that enables the JBL Xtreme to fasten into loops for added portability. It comes in black, blue, and red.

The build of the JBL Xtreme is outstanding. The speaker grille is made with woven fabric that not only covers the speakers but also protects them from splashes of water, thus being Splashproof, which is another feature that makes the JBL Xtreme really outstanding. Along the sides are the visible passive radiators that produce extremely strong bass. The feel of this JBL speaker is also great with it being portable (despite being somewhat a bit heavy) and easy to grip.

The JBL Xtreme has got numerous functions that add to easier control over devices. Across the top part contains the power control, volume buttons, Bluetooth pairing button, play/pause button (that also functions as track navigation for tracks and call answer/end for speakerphone), as well as JBL connect button (that serves as a function in pairing multiple JBL speakers for a single or same audio source). Meanwhile, on the back end of the JBL Xtreme is where the power adapter, 2 USB ports, and the 3.5mm aux input are found. These connections at the back are well protected from different elements by a zipper cover.


JBL Xtreme Portable Wireless Bluetooth Speaker – Connectivity

The JBL Xtreme can be connected via Bluetooth. So for as long as your device supports Bluetooth, using this JBL speaker is not a hassle at all. For non-Bluetooth devices, you can still use its 3.5mm aux input (take note only that a cable is not included here so you need to purchase one for yourself).

Pairing our devices with the JBL Xtreme was not a problem at all. It was easy and smooth process. By the way, the JBL Portable Wireless Bluetooth Speaker can pair with up to 3 devices at the same time.

As mentioned a while back, you can also make use of their dedicated app, the JBL Connect to pair up multiple JBL speakers at once to take advantage of stronger and louder sound. You can download and install it for your iOS or Android devices from the App Store or Google Play Store.

Lastly, we also mentioned about having controls for speakerphone capability. This means that the JBL Xtreme can also handle wireless, hands-free phone calls. Trying this feature was fun and not disappointing at all. The quality was great and no problems were encountered during testing it.
