W-KINGPortable Speakers Bluetooth Wireless Loud, 100W Max Waterproof Outdoor Bluetooth Speaker Big Party Large Boombox Subwoofer*2, 60W Exlarge All-Round Bass Passive Radiator/40H/PowerBank/TF/AUX/EQ

For starters, this small speaker really kicks out some sound and while it isn't as clear as a comparable Bose or Sony, it isn't far off. I waited a bit before writing this review as I wanted to see if the battery held up as long as they promised and I have to say this speaker will run nine hours at full volume before needing a recharge. I have taken it out on the golf course 9 times now and charged it 3 times during that run with no reduction on battery performance. I put it on the floorboard of the Golf Cart and the only thing you can hear is the music. You can still hear the music well from 25 yards away while on the green so it is perfect for the course. The equalizer button only has 2 settings, Bass and less Bass so don't overthink settings. The bluetooth connection is pretty good at 50', but it will start to fade at that point, not sure if this is due to my Samsung A16 or the speaker. The speaker takes calls seamlessly and the microphone is adequate as long as you don't stray to far from the speaker. The speaker also works well indoors and I will add that setting this speaker on a normal table greatly extends the sound. If you are looking for a balance on price and performance I don't think you can beat this speaker in the 80watt range.

I just played my D9, for 10 hours, no downtime, half volume power, and still have 70 percent power left. A good 60W speaker system, well designed, durable, and a water resistant cabinet to boot. The equalizer is dual settings, with the bass incremented in one setting and the other is less bass, and more of the singing, and voice overs, going out clearly. I tried to listen to it on full power, bass EQ, and it was clear, no distortion, like some others, I own(ed). I move my unit in my backpack, so I removed the plastic handle, (the screws are at the bottom of the handle, hidden by a plastic cover, on both ends), if fits in my backpack easier. The case is made of durable plastic, which would withstand a sizable fall. My only shock to the system, was from the top of the roof of my home, (15 feet), fell to the grassy yard below. It would have done damage to the handle, if it were on, I believe. The unit sustained no damage. No operational problems at all. Luckily it did not drop on the passive radiator, on the back, it would is the most vulnerable spot. I tried to get warranty, using a card, that came with the unit. The website did not work, to do that, so I wrote them, and asked how do we handle this. support.amazon@w-king.com is the email I wrote to. They replied with an email, recognizing the failure of the warranty website, and asking that I keep and retain, the email, as a registration for a two year warranty. Now then I did send them my name, day of purchase, date of delivery, who I bought it from, and the number on the front of the box, the unit came from. I could not find a serial number, on the unit. Bare in mind, what you are getting for less than a hundred dollars. This is an excellent BT speaker, and a good price point, well researched and made. In comparison to my JBL, w-king wins. Upon ordering this unit, go ahead and order a charger, made by w-king. W-KING USB Charger, at Amazon, is where I got it. It comes with an old style usb port, (type A), I believe. It will hook up your C power at the box, and the A port, in the charger. This charger is a 5v, which is the max allowed in box, and it will have the usb Type A, needed to power up. Now then there is a charge cord, well made, braided line, with a type A usb on one end, and the C on the other for the box, included with the unit, along with a line for the jack, 3.5mm, to go wired. NO CHARGER though. If you have the type A usb acceptable charger, and its at least 5v, then you wont need a charger. So, we all know that ratings, for water resistance, are internationally known. IPX6 is listed, in the w-king description. It is also followed with: waterproof....now the standard does show a water resistance for 1 minute, from a .49 inch nozzle, from many different angles, with no disruption of operation, or loss of operation. This unit is not waterproof, but very water resistant. For the price, there is no way you are going to get waterproof, (immersion). Just know that it will put up with a little splash, dripping hands, some rain, or in my case a water bottle, in my backpack, leaking most of its contents, (8 to 10 ounces), all over the case. No issues. I would also recommend you dont play this unit, on its ends. Im not sure of the principals behind it all, but the unit did not sound up to my expectations, playing on its end. So dont stand them up on the ends, (unlike the D8, this one has no speakers on the ends), it changes the quality of the sound, lay flat on its gripper surface pads, and enjoy. I will buy another D9 and pair them up, to get true stereo. Best BT speaker for the money. I will buy more for my kids, as the need arises. Very happy.

I bought 2 of these to dj with, and haven't tested them out at a venue or a house party yet, but I have used them in several environments, and I can tell you that they really are punchy and bassy. I take one everywhere with me in my SUV, I've tested it out in different rooms of the house, I've synced 2 to see how loud it gets, and I have noticed a couple of things to highlight. 1. They get loud, but not ridiculously overpowering, so that's a plus. The volume when turned to the lowest setting is still kind of loud, like for example, if you're trying to listen to music quietly, or at night. They sound great in my SUV. If you put one of these in a boxed in area, they bump so hard, for example, here, on the floorboard of my front passenger seat, yeah.... Boom boom boom boom. Thumps. So, you can get some super serious bass coming out of these if you put them in some kind of old school carpeted speaker box maybe? That's just an idea I'm thinking about doing for my gigs. They're ready to go right out the box. They take a while to charge, but with the sound these things are producing, the drawbacks (which aren't many) are heavily overpowered by the positive aspects that these speakers have. They're light, they're durable, they're easy to sync up, and they're great sounding. The price of these I would say is good, and if you order 2 of them, you definitely have a super great quality Left/Right audio mobile sound system that you can take with you on the go. You definitely need 2, but they're worth the investment. I strongly suggest that you pick these over all the other available options that are on Amazon. These really are king. Wow.

Have had this product for a year and it works well. Sound quality might be better but sound volume is acceptable and battery durability is great !. I like you can also charge your phone and keep playing music.
