I believe harran out did themselves on this speaker. Not only can it pump out impressive sound all day long it’s ideal for those who enjoy out door activities. Personally I wear the speaker like a satchel and the grooved strap keeps it from flipping over to my front side. if you own a boom box 2 and pair it up with the extreme 3 you’ll notice how beautifully they complement each other. The thing about JBL you can never have enough and I’m looking forward to reviewing the charge 5!
There are a lot of complaints about the grinding of high frequencies. It is necessary to modify the SBC codec to two-channel, with the bitpool settings. Or apply the ability to use other codecs with higher bandwidth to improve sound quality. I ask you to transfer this to the department that is engaged in the development and updating of software. There are already cases of returning the Xtreme 3 due to this flaw!
Got it to add to my JBL Xtreme and Charge 3. Does not connect to them. JBL has 3 versions of Connect, Connect + and PartyBoost. I updated firmware for the Xtreme and Charge 3, now none of them connect at all. My cheaper older Xrtreme is louder than the new Xtreme 3. If your wanted to add to your JBL collection, beware and get informed. If your buying your first JBL, than overall its a good speaker. I'll be returning mine.
I would recommend this to a friend!

Our JBL Xtreme 3 has the PartyBoost feature, it is compatible with other PartyBost enabled speakers like the Boombox 2, Flip 5, and Pulse 4. Our JBL Charge 3 on the other hand has the JBL Connect feature. When the firmware is upgraded for the Charge 3, it can be connected with Connect+ enabled speakers like the Xtreme 2, Pulse 3, Flip 4, Charge 4, and Boombox. Our JBL Xtreme has the connect feature that can wirelessly link multiple JBL Connect enabled speakers.

I checked out some other brands for comparison before making my decision to try the Extreme3. In the end it won out for me. It was close but the waterproof & dustproof features helped sway me. The sound is awesome for it’s size & you can take it anywhere. I use it indoors & out. It sounds great everywhere & the battery lasts me for days. I also thought about the boombox2 but decided it was a bit too large. After playing it though I might have to come up with an excuse to get it as well.
