Customer Ratings & Reviews

The xtreme4 has a great powerful sound. Not too heavy so you can carry it around with you inside a backpack which was what I needed to do but I didn’t want a smaller speaker because those do not sound too great. It is the size of a radio too so it does fit inside a backpack.

Sounds great good base long battery life Well built

This speaker is a TANK. Sounds great & battery last a long time on a single charge. Love how easy it will be to replace the battery when the time comes. Well worth the money

Used it in a parade and it blasted out the other Bluetooth speakers that the floats around me had. The bass is awesome. Great sound quality.

Good sound quality. I wanted something a little rugged for outdoor parties. The speaker volume is plenty loud enough. Unfortunately there's no way to adjust the bass, so if it's a bass heavy song you'll hear that. It's not a big issue for me so I still rated it 5 stars. That would be the only thing I would change about the speaker though.

Wow nice unit for bringing to community pool or outdoor activities. We also have Charge5 which is wonderful but this is a very noticeable upgrade in highs and lows. We are fans of both and will continue to be jbl fans. Worth the extra $120 from charge5

Once I was able to connect to our home stereo system, it has provided a good outdoor listening experience for fire pits and bbq. I have not had to recharge the battery yet so I am unable to speak to the battery life on a charge.

Yes yes yes. The best bt speaker by far. Non stop play all the time. I love the strap also.

Since i have bought a jbl flip 6, i just had to buy this extreme 4. I love the bass, but they need to update the jbl app to have more settings for the equalizer part. I would for sure suggest anyone/everyone to get one of these if they have a chance too.

I got this for a great deal and the sound quality is amazing for what I paid for. One of my best Bluetooth speaker I purchased.

Amazing sound, awesome bass, extreme clarity. The app also works well to set preferences with the equalizer. Very happy with this purchase!!!!

Love this for work battery last almost all day, bring ur portable charger n ur set… n thats all day with it blasted listen to it like a normal human being n itll last 2 days

This product is Awesome. The sound quality and base are phenomenal. It is easy to use and can take it everywhere. The look and style is very sleek. I bought 2 of them one for my husband and one for my son for Christmas. They love it!

My husband was looking for a speaker to take to work with him… he now carries this everywhere, he was cleaning the floors and had it across his back. Connects easily, sounds quality is great, volume control is great. Easy to clean.

JBL has done it again, I love it!!! The the clarity of The Mids & Highs as well as the bass are off the chain. Just put this in the corner of any room and you will be able to tell the difference when it comes to the bass. I recommend this most definitely hands down!!!

One of the best portable Bluetooth speakers I own ! Great sound and excellent bass!

Great sound and range.. Bass needs tweeking on some tracks while listening. Powerful bass

I roller skate during my free time and I don’t like having my ears plugged up 24-7. This speaker is lightweight, comes with a strap, and it’s a portable charger for my phone. Best investment by far.

Awesome sounds good and the charge during a lot!!!!

This is the prefect size speaker that has a big sound. Very impressed with the sound and not big or heavy which makes it an easy carry. Better buy verses say Bose at a $100 more.
