One of the best Bluetooth speakers to have great sound the battery last time

Love this speaker! Great sound quality, clarity and bass. Would highly recommend to any music enthusiast!

Impressive sound for a Bluetooth speaker. Hita upper range subwoofer frequencies and Bluetooth compression is practically unnoticeable. Battery life is insanely good.

I love Karma Garden speakers specially JBL always has that bass and this is no surprise it's excellent droppin the bass...

It is an excellent portable speaker, I highly recommend it!

I really enjoy this speaker. I upgraded from a Sony waterproof and dustproof speaker that i had for several years. The battery life and sound quality is amongst the best in this price range.

Open box was a great buy. Product came with everything. Speaker wasn’t banged up or broken. Bass is substantial and is audible in a truck shop bay, even while working. I was looking for something I didn’t have to completely worry about ruining if oil or diesel got near it. Even after blasting at full volume for an 8hr work day, it didn’t die. I would say even at full price I’d say it’s worth it.

Look JBL is a good brand but their prices are almost criminal. This speaker i do feel deserves my money but it might not deserve yours. This speaker blows the old JBL Xtreme 3 out of the water. More bass, better instrument seperation, better details and louder by a good bit as well. Now while justyfing $379 is hard i feel the app support Aura cast and other nice features make this still the leader in its department. Good job JBL.

Best portable speaker I have used so far. Great battery life and sound

Love that i can adjust the equalizer with the Jbl app. Perfect battery life.

I used these speakers for either my on to go workout speakers, or I used them on my friends boat when we’re out fishing. Either ones, they give me the best sounds I can buy on the market! Regardless of all the winds, I can still hear it loud and clearly.

Awesome, comes in handy for that much celebrated outdoor blast. Can't stop for my next burst.

This speaker is loud and powerful. I have other JBL speakers that I connect to it. It works very well.

I looked at this a couple times. I have a charge 3 that I recently replaced the battery on for less than $20 so why spend almost $400 for a new one. But it went on sale, had a strap which I wanted and sounds good outside. I did have to turn it down on the little glass table when outside. Base was just too much and it was rattling. I’m happy with my purchase at $250 price mark.

I loved how it says JBL on it and overall it has a nice blue color

This device works very well. The linking process is easy. The sound quality is excellent.

I Love the Jbl Sounds great and has long battery life i use it in my UPS truck and it sounds great and I don't have to worry about charging everyday because of the long battery life

Great sound and well built! I take it out on the lake every weekend.

I bought this JBL extreme 4 Bluetooth speaker as an excellent open box item. I received all original accessories with the original box. I once had a JBL extreme 3, Bluetooth speaker and it sounded amazing, but the extreme 4 is a little louder and clearer, and the battery can be replaced with ease. It can be controlled with the JBL app. When you hear the extreme 4 from the distance, you'll think that a floor model speaker is playing, until you get closer and find out that it is the JBL extreme 4, which is a big little speaker.

Love the sound quality it and the base and the fact that you can connect it to another one
