    • Absolutely bombproof
Color: blue
Bought this after using a friend’s, was very impressed with the sound quality and volume as well as the tough woven shell and silicone (I think?) end piece diaphragms. Size is comparable to a nalgene so easy packing in a water bottle pocket. Also liked the aux port for my iPod, though I’ve since bowed down to Spotify and would just as soon get the newer charge 5. Used a lot last year at work (construction) and partying. battery life is very impressive, will charge my neglected phone and play loudly all day which is real nice. After four or five months I noticed the cover that protects the charge and aux ports was splitting a little where I had to use a bit of finger nail sometimes to pop it open, especially if my fingers were a little wet. Despite that little flaw, the water proofness is pretty perfect. I tested the buoyancy of this thing many times while floating and rafting as well as using daily as a lift attendant all winter in a wet snowy wet place. Was planning to ask for a new plug cover, it seems easily enough replaced. That was until however until the poor little thing was set too close to a bonfire late at night and, by the time I noticed the flames were licking it and grabbed it (still bumping loud tunes) the rubber ends were soft and boiling hot and the fabric weave shell kinda seared my hand. I threw it in the sand and hit the power button with a stick. Thirty minutes later I turned it back on and the speaker sounded like nothing had happened when by all rights it coulda just blown up. Bonkers. Soooo I’m not claiming that it’s fireproof or anything but I am claiming that this thing is pretty dang tough. I’ve used and abused the thing since the near meltdown and it sounds great and has great battery life. That was until however the poor thing fell unnoticed out my passenger side door and sat in the gutter for a night, then got driven over the next morning by my Chevy 1500 when I left for work. I found it that afternoon in the ditch kinda cracked up and real sad looking under a few leaves. Turned it on and bududududuh! It lit right up and connected to my phone. Sooooo I’m not claiming that it’s invincibly uncrushable or anything but I will tell you that I’m buying another one soon. My current been-around-the-block-and-under-the-wheel speaker has a little static noise issue every ten or twenty seconds and is a bit quieter after the partial crushing but still good enough to listen to podcasts in my very loud crunchy old truck. Bonkers. Definitely with yer money. Ohhhk one small add on complaint sorta thing is that the only way to check battery involves turning the speaker on which makes the startup budududuh noise which can be very loud sometimes. Wish there was a way to check battery without the noise. Still gonna buy another though. ... show more

    • They sound great and are very versatile.
Color: blue
I got two of these speakers factory renewed. They came packed in plain boxes with complete packing and the accessory recharging cables. They charged up well and worked right away. There is a bit of a learning curve to the JBL controls, and instructions are sketchy at best, even on the JBL web site. But there are many YouTube videos explaining details and operation. The sound quality is really good with ample but appropriate clean sounding bass. I've connected wired and with Bluetooth and quality is great. For music, like from SiriusXM, I can have one speaker connected wired, with the other on Bluetooth from there. I'm still experimenting and there is a setting for stereo where one speaker is Right channel only and the other Left. I'm satisfied that both of these speakers are working to full capacity and I found no flaws at all. There is no indication of previous use visible, they were both very clean and looking like new. One thing to note, when using with our outdoor TV, the Bluetooth audio is just slightly delayed so that it's not in lip synch when people are talking, and this can also happen occasionally when wired too, which I don't understand, but I did find some methods to correct online and they work. Both speakers are pretty quick to set themselves up on Bluetooth and start playing, and volume is individually controlled on the speakers for balancing. You can apparently connect a large number of these JBL speakers (over 100) to cover a large outdoor area. Two was sufficient for our deck area and I can grab on to go to the other side of the house to an outdoor seating area and the Bluetooth worked flawlessly. I haven't tested range but it's better than most I have used. I have killed soundbars using them outdoors and other wired solutions are limited and there's a lot of work to run wires. I can use by the hot tub or the outdoor shower and not be concerned about water as they are not going to be damaged by water. These JBL speakers can be placed anywhere and changed around at any time to suit your needs and particularly for the price I have no reservations in recommending them. ... show more

    • Durable & Reliable.
Color: blue
This is the second one of these I've purchased. A really great speaker. Syncs flawlessly with the JBL app as well as any bluetooth system. Sound quality is fantastic, and the thing is incredibly durable. I've dropped it from shelves, countertops, and desks onto concrete and it's only suffered some minor cosmetic damage. Battery life is pretty incredible; I run it at my archery range in the background for 7 hour program shifts and it doesn't need a recharge. Would definitely buy again in the future! ... show more

    • It's great sound
Color: blue
The first day I had it I dropped it in water and it still works it's been on our construction site for a few weeks now and there's no issues it can hold a charge for several hours

    • Good quality speaker for the $
Color: blue
Def think the charge 3 has better sound. I have both and you can def tell the diff side by side. But the charge 4 is still great quality and you can connect more than 2 compared to the charge 3. But still a great speaker for the $

    • Multiple connection choices
Color: blue
JBL Charge 4 /multiple connection possibilities. I was looking for a portable speaker with 3.5 connection, the JBL Charge 4 in addition the Bluetooth was what I wanted in my portable speaker. The sound from the 3.5 connection to my ears is more defined than Bluetooth. The size was also an important factor for deck and poolside listening, more than happy with my choice. + very rugged construction, + refurbished model lower price. A win win for me. ... show more
