[This review was collected as part of a promotion.] One of the best portable speakers that I've owned. Between the app that provides more settings to the sound quality, it's amazing. I've used this outside when working cleaning up the backyard and around the garage when working, and the bass is amazing for such a small speaker. Its the perfect size between too small/quiet and too large to take on the go, it's perfect. The app has more controls to link together speakers, change bass settings, updating software and probably more to come. The battery life is pretty awesome too, with the bonus of USB-C charging, so I can use the same power cord that my phone uses.

[This review was collected as part of a promotion.] This speaker has hit a lot of marks. It's portable, waterproof and has a clear and crisp sound quality. It sounds like a full home surround system on wheels or your shoulder (lol). Great addition for all outdoor fun yet can be used indoors too. If there was one thing I would change, I would add a carry case or bag.

Otherwise, I would definitely recommend as an owner of various portable speakers of various brands, this is hands down the best. This is sure to make the next day at the park or beach a hit.

[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.

Excellent quality, this is my 4th JBL speaker in 5 years.

[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.] the first thing I noticed was the weight. A heavy box indicting to me a solid well made speaker. I want to put this to use in the back yard while gardening or grilling with friends while playing great sounding, quality sound. the audio is perfect even from a distance. The first connection to my phone was easy. Push the on button and than the bluetooth connction and its good to go. I also connected to my pc just fine.

Solid contruction, powerful sound and a great design looks like a airbus airplane, totally recommend
