Waterproof, Portable, and Rugged Outdoor Bluetooth Speakers with Loud Sound and Deep Bass, 50hr Battery Life, Dry Storage + USB Charging, 100ft Bluetooth Range. Built to Last and Fully Serviceable!

Let’s get the Price point out of the way. Yes my feeling is $299 is the right price for this Item. Having said that we are paying for its Unique qualities and performance and ruggedness. Last but not least it’s so cool in every way. Musical Performance? Very good. Solid low end well balanced natural sound. When I say Natural I mean I’m not hearing all sorts of artificial equalization like allot of odd shaped Bluetooth Speakers and I own and have tested so many. I’m a musician and an Audiophile who loves the great outdoors. This is perfect for that type of person. It’s Smooth and Warm to my ears. Battery? Blows away any speaker in its class. No worries period that you will go powerless for an entire day of use and more. Emergency charge for your phone is a nice touch. Built in Storage is just priceless. Great for cables and whatever is important to you. I purchased a small Otterbox case to put my phone in with cables and Adaptor for Demerbox. Fits quite nicely. I’ve taken it to play basketball, Frisbee, in The Woods. Water or damage is of very little concern. I’m pleased in all areas I highly reccomend this to all Adventurers. The unique Qualities of this device helps ease the pocket pain. If you have to save it’s worth the wait.

This speaker is awesome. Expensive for a Bluetooth speaker? Yes. Worth it? Yes, yes, yes!If you’re comparing the sound quality to an upper level Bose or equivalent Bluetooth speaker then you may be a little disappointed. These speakers aren’t water proof and incredibly durable like the Demerbox is though. The treble leaves some to be desired but that is characteristic of water proof rubber speakers. This isn’t a dealbreaker at all though. While it isn’t the clearest speaker in the world, it makes up for it with punchy bass and solid mids, not to mention it can get super loud. I had a Big Jambox and it gets louder than the big jambox could. When the speaker is turned all the way up it doesn’t crackle at all. The sound is perfect all the way up. We used it on a boat while tubing and were able to jam out to good tunes even with the 150hp Mercury revved all the way up.The added feature of a Bluetooth charging port is absolutely clutch. We easily can jam out all day with the super long battery life and then have the phone charging at the same time inside the speaker while maintaining waterproof status with the plug installed. I threw the speaker in the water with my phone in it and it didn’t leak a drop and sounded cool reverberating on the water.My favorite part beside the killer battery life which will easily last you a week or more on a single charge depending on how many times you charge your phone, is the ease of use. This speaker has 1 button. You turn it on and it links up with your phone instantly. You can control the volume completely from your phone and don’t have to worry about turning your phone up and then dealing with another volume on the speaker too. Literally just turn it on and start jamming. Nothing to it.One last feature I love is the long range Bluetooth. I was jamming in the backyard, went inside to do some stuff and had my phone in my pocket and my friends said it never lost connection at all. I haven’t gone to the point where it disconnected yet.Overall, you have to decide what you’re going to use the speaker for. I am on the water and outdoors all the time, fishing, wake boarding, bbqing, etc and this is perfect for that all weather rig. If you plan to use your speaker inside and don’t plan to move it then id say go get a bose. If durability and practicality aren’t a need then get a bose. If you want to jam out with all your buddies and get sweet sound quality in literally any situation you find yourself in and plan to ever listen to your tunes near water or outside.... get the Demerbox. It’s the only speaker I use now and I have a few other ones. Super sound and solid construction (I break everything) make this the one for me. You won’t be disappointed.

I wanted to love this. The style is awesome. The fact that’s it’s also a little dry box is awesome. The battery life is awesome. But the sound is just average. And I was willing to accept average sound for how cool it was until I put it next to a turtle box. The turtle box sound is so much better. High volume low volume doesn’t matter turtle box sound is just superior. So even though I wanted to keep the demerbox cuz it looks so damn cool had to return it and keep the turtle box.

Lost a star because of price. If this was $199 it would be the greatest thing of all time. At $299 it would be expensive but worth it. At $399 it is really hard to justify. There are great quality BT speakers out there with similar features for WAY less.Also, would love a way to tell how much battery is left. Can't even tell from your connected phone.That said, if you have the money and don't mind spending $100 more than it is worth then this is a great product. Everything comes as advertised. So, I am going to try my damn hardest to get my money's worth!

I ordered this because I like to camp and my current bluetooth speaker doesn't have the battery life I need for a weekend in the wild. I wanted something rugged, had good battery life, and good sound. I have not had a chance to take it camping yet but I have had a chance to run it through some tests here at the house. The speaker I am currently using is a JBL Extreme. I love the JBL, it has awesome sound but it only have about 4 hours of battery at anything over medium volume. Plus it is not as rugged as I would like it to be as I am going down a river in a boat.The Demer Box advertises 40 hour battery time which I find amazing, If it doesn't live up to that claim I will update my review. The Demer box is tough as advertised. The Pelican case is very strong and is everything I could wish for. I feel confident it could take whatever I throw at it while I am camping. It's range is as advertised also as I was able to get about 100 feet away from it before it started losing signal. It is simple and easy to use. I would like to see a battery indicator but I think that is a common complaint. The sound is good but a little less full than my JBL. It doesn't distort all the way up to my almost full volume. At full volume it does start to distort, especially with heavier rock. It is loud but not as loud as I would have hoped.All in all I am looking forward to using it for camping. In my initial opinion I am not sure it is worth the price because the sound is not what I would have hoped it would be for that price.
