Question: Is it water-PROOF? Or water-RESISTANT? Is there a cover for the mini-usb and 3.5mm audio jack on the side?
Document: It sounds the same whether its upside down or right-side up, but it's an annoying quirk.Third, there is a rubber grommet that goes in the audio jack and USB port to keep water out. It seems like this grommet could have been included in the body of the speaker. Instead, it is a separate little plug that I need to add when I leave the house.
I use this with an iPhone and the UE Boom iOS app, which is highly recommended. The app give you battery status and some equalization options, and also changes how the volume is controlled that is a little more intuitive. It also includes an online instruction manual. As an initial matter, the early production units apparently did not come with the little rubber cover that covers that 3.5mm jack and UBS charging port on the bottom, which is unfortunate.
Simply awesome! And I should know. I've owned just about every external speaker ever made. Here's the short list:1) good clear LOUD 360 sound near and far. 2) water resistant for outdoor use. 3) 15 hour battery life! And an audio battery meter! 4) easy blue tooth paring and speaker phone capability. 5) USB & headphone jack with protective rubber caps.
Nicely packed, but does not include a carrying case. This is supposedly because it is rugged enough (stain- and water-resistant) to not need one. However, in early batches, there are two ports that are uncovered - the 3.5 mm jack and the USB charging port. I'm told that this item is supposed to come with some plugs for those, but my unit did not have them.UPDATE: Logitech responded to this review and contacted me about shipping the parts.
you can buy another UE Boom and have them play together via phone app android or iphone (one as a left and other as the right speaker...or just have them play uniformed, one on each side of the surrounding area)2.) can get splashed with water (not submerged) and it's all good. Will continue to play and not damage anything.3.) Has lanyard holder. I used this and hung it up using a small carabiner under an umbrella and worked like a charm.
It's been able to handle everything I throw at it and stains easily come off by running the speaker under a flowing faucet. Battery life is great, I usually get close to the advertised 15 hours and it's always at least double what I used to get with the SoundLink Mini.All-in-all, I think this is the best $200 Bluetooth speaker on the market as it has excellent battery life, is stain and water resistant, and the audio quality is really nice.
(powers down after 15min. of no audio source input).The screw mount on the bottom works wonderfully with a Joby camera tripod, and it is clear UE is working well with consumer feedback as they have now posted a form on their support page that I filled out to get a rubberized USB/Aux protective cover so the unit is fully watertight.The support folks also answered my questions very quickly via e-mail about warranty (full 2 years) and replacement battery.
I will mention a buddy bought one and it did not come with the rubber protector gasket thingy (official terminology I'm sure) that goes on the bottom that plugs up the 3.5 mm jack and USB charging port, so make sure your has one. Important to keep that "gasket" piece installed if around a pool or a very dusty enviornment. All in all feel very good about purchasing this unit, you should have no regrets.
The last important aspect of it that made me choose it over other competitors is the user-friendlyness, and what I mean by this is that it charges by mini-usb (unlike the bose mini soundlink) and it also has a small d-ring which allows you to hook it to things like a bag.
The wired audio connection, charger slot, and the D clip to hang the speaker are all on one side. The power button and Bluetooth button on the other. It will stand either way and there is a slight recession so putting the power button and Bluetooth on the bottom will not cause the buttons to be pressed and you only use those buttons once so no big deal if they are on the bottom.I only purchased one of these. I may need to get a second someday.
Answer: I have not submerged it completely...but I have put it through everything short of that: 1) In the shower - mostly soaked the entire unit countless times.2) By the pool (with my kids) - it got splashed, bumped, fell off of benches onto concrete.3) Can of soda exploded onto it (overheated in a truck cab) - I was able to wash it off under a weak stream of water, no marks left.4) BURNING MAN - this thing survived a week in the Black Rock Desert and managed to bump out very high-quality tunes all day long in the playa dust.Overall, I'm a VERY happy customer.
