JBLXtreme 3 - Portable Bluetooth Speaker, Powerful Sound and Deep Bass, IP67 Waterproof, 15 Hours of Playtime, Powerbank, PartyBoost for Multi-speaker Pairing (Black)

Was really satisfied with the purchase of this speaker.I originally bought a Sony XG-300 refurbished and the sound quality was garbage.Came in a regular box with offbrand charger etc.After less than a month the speaker blew and the sound quality started sounding like garbage.So I sent it back and got a JBL extreme 3.And i bought it refurbished.Came brand new in the box.Listen to the same music i did on the Sony and the JBL has no problems at all.I put mine on a bike and it sounds great and isn't half as heavy as the XG 300.

Awesome!!

I use this speaker at work this thing is loud we have store music playing 24/7 and this speaker makes it seem like it’s on mute! Only drawback i have is that it can’t connect to every JBL which is a little disappointing, strong battery life so don’t gotta worry about it dying on you!

Great speaker overall, battery life is 8/10 sound quality 8/10 however I wish it could get a little bit louder. I understand that this a good durable hybrid speaker so no real complaints. Durability 10/10 I beat the heck out of this thing. From throwing it into the river to sand in it from the beach it seems to be unstoppable.

Really happy with my purchase. I own a handfull of bluetooth speakers so i have some experience. I wanted a loud enough speaker to use outside at my pool. This definitely fits the bill where my others don't quite cut it.Good sound quality, very clear.The selling features for me were the high power output at 100 watts and the potential to add extra speakers using the partyboost. After hearing the volume, I doubt i ever will.I also like that it comes with an app to update software and have access to an equalizer.For the pricepoint, I feel i got my money's worth.

Overall I like these speakers. They sound good. Plenty of volume and base. I like the strap and the hooks. Feels like good quality - mostly.This is my first time trying JBL speakers, and unfortunately, I ran into a bad batch of audio jacks. My first Extreme 3 was perfect; but I also got a Boombox 3 at the same time, and I the audio jack was too loose to hold. I exchanged the Boombox 3 for another, and it had the same issue. So I returned that, and got a second Extreme 3 - and unfortunately it also has a loose audio jack. However, the jack holds just well enough that I decided to keep it. For me, the audio jack is a critical feature.One of the main reasons I got this speaker was to see if PartyBoost would work as a whole-house audio system. Unfortunately, it doesn't. It's extremely sensitive to interference. If you put the speakers in separate rooms, the sound like drops out and sounds staticy; and if you get too close to one of the speakers, it gets worse, and in some cases the sound completely stops. In fact, even in a single room, the speakers have to be pretty close without stuff or people passing in between.In fairness, I never read or heard that PartyBoost would work across rooms (and I figured it probably wouldn't); and I think all they say about it are meaningless things like "amp up your party" and "take your party to the next level". I suppose those are literally true in the sense that the volume increases. So, aside from the stereo feature, which I don't care about and didn't try, this is almost a useless feature.So, since it has two major features which I consider to be somewhat defective, I'm only giving it 4 stars, so that the reader is aware that something is probably not as expected with this speaker, as advertised.However, so far, other than the audio jack and PartyBoost, I am quite satisfied with this speaker.I haven't tried a ton of other BT speakers, but I have tried a couple of good ones, so I'll tell you how it compares.First, is my last speaker, which was the Soundcore Motion Boom. That speaker is basically like a direct competitor, and it sounds decent, but it does drop or flattens some of the sound detail. I think the Extreme 3 sounds better, but not so much better that it's obviously worth the increase in price. The Motion Boom is currently going for $85, and I think I paid like $120 when I got it, but the Xtreme 3 is currently going for $380. (Also just realized I been spelling it wrong this whole time.)But, the JBL has a few additional features. 1) Tweaters. 2) Audio Jack! 3) Anchor hooks. 4) Carrying strap. (And I guess technically PartyBoost.) But, the Xtreme 3 doesn't have a nice handle like the Motion Boom does; and I kind of think the round, rolly body of the JBL is kind of a bad thing; whereas the Motion Boom has a rectangular body that won't roll away so easily. I kind of wish they both had a handle and carrying strap, so its kind of a trade-off; but I do think the anchor points on the Xtreme 3 are a little more flexible. I can just attach a handle, if I can find/fashion one. I could also do that with the Motion Boom (and I did), but it's more awkward, since the handle is basically a wide tube.The other speaker I can kind-of compare it to is the Sony SRSX5, which is a much older speaker; and it's been a couple of years since I had it; but I remember it sounding very nice. Well, I think the Xtreme 3 is probably just as nice, except a couple of small differences. I think the Xtreme 3 is probably a little more punchy (as the Motion Boom is) and I suspect that's because of their outdoorsy, waterproofy design. Also, the SRSX5 is kind of bass heavy, and has a more mellow sound, which I kind of didn't like about it. But either way, I think some people might prefer either sound over the other; so they're about the same in my opinion.Other than that, the SRSX5 and Xtreme 3 are not really comparable, because they're different sizes, and the SRSX5 is not designed to be an outdoors speaker. They're designed for different environments. But I think the sound comparison is still relevant and valuable. In many settings, I think they'll have similar sound abilities. I would think the Xtreme 3 could get louder than the SRSX5, since it is bigger; but honestly, I don't know.I guess another thing I can compare on these 3 speakers is quality and durability; and overall they all seem like good quality, durable devices; with the exception of that one Xtreme 3 with the loose audio jack; and unfortunately, since I found 3 JBL 3-series speakers with such loose audio jacks, that casts some doubt about the quality of the JBL brand; especially in $300-$500 speakers.

Great speaker, use it working my ranch. It could be a little louder.

Just the right size and music output I wanted.
