iPhone 7 8 X Splitter Dual Lightning Adapter (White)

I use this speaker a lot, and have been extremely satisfied with it. I have had this on my kayak out in the gulf, out at the beach, dangling from my bike on long rides, and every night I link it to a tablet and play white noise (rain) in my kid's room. The battery lasts as advertised or better, and the sound is great for the size. I will probably be buying another as we keep finding more and more uses for it. I have two other Bluetooth speakers in use around the house, but this one was the best deal for the cost.I would not recommend if you are looking for a loud speaker to cover open spaces for great distances. This device excels at short range outdoors and small rooms inside.Only other thing I have noticed as a negative is that it will disconnect from Bluetooth devices while plugged in and charging. It works perfect though, when I have already charged it and it is not plugged in to a power source.

First one wouldn't charge, sent it back for a refund. Ordered another and it turns off by itself about every ten minutes. Contacted the manufacturer directly and the website said they would get back to you in 12 hours, been a week and nothing. The speaker was nice design and sounded good but just didn't work either time. Amazon was great with processing the refund but buyer beware with Youmoon!!

Out Of The Box: The speaker had a really nice look and feel to it. Fully rubber coated giving a non-slip grip as well as a climbers clip to secure it. The sound was crisp and clean up until full volume, but with the power this little unit can produce I do not see us ever putting it to its max. The side cover is somewhat flimsy which covers the SD card, charging port, and 3.5mm input. It connected quickly to blue tooth and didn't appear to have any interference with other devises in the room.Usage: We took this speaker on vacation with us were we took it on a long walk synced to my phone and placing the speaker in my pocket. (It is just small enough for it to not be uncomfortable while wearing mesh shorts) We did have phone calls come in while walking and were able to use the built in microphone phone call setting. Although this feature I thought was kinda a joke when i saw it came with the speaker, i have to admit it is a pretty decent feature. The call was clear on both ends and it was easier to use the speaker in my pocket than take my phone out of my running sleeve. The next day we used it with an 8 gig SD card filled with music. We found that anytime you turn the unit off using SD card it starts back to beginning of the card. If there was an option to play random or resume would have been much more convenient instead of having to fast forward and try to relocate where you left off. If i was just going to use the speaker and let it run all day this would have been fine, but I choose to turn it off when we stopped from time to time. Although I am usually tethered to my phone I went with the Youmoon mostly because it did offer the SD card feature as especially on vacation there are time I want music but don't want people calling me while I am trying to relax.Why Only 2 Stars: We used the unit for two good days (which the battery lasted through) but on the third day after a night on the charger the speaker would no longer play from the SD card. A red blinking light would flash when the card was slide into the device. I do not know if the speaker we received was a dud or if this is what can be expected under normal use. We did put it to good testing on the first two days and it was humid, but an item that claims to be water resistant should not be subdued from humidity (if that is what killed it)Long Story Short: The device itself was excellent in sound quality, blue tooth connectability, battery life, and design. The fact that is you plan to use the SD card be aware that it does not resume where you left off (a big thing in my book). Life expectancy of the device (I might have gotten a factory defect) only lasted a couple of days.Would I Purchase Again: I am torn, although the sound quality was really good (especially for the price) I think at this time I may look at other devices before making a decision on a replacement speaker.

For the price this speaker sounds good and is easy to use. Not perfect since we dropped it and the speaker cover popped off. It appeared it was glued on, so we just pushed it back on and it appears to be holding okay.

My gf loves it but it only plays for 4 hours then it turns off the she has to recharge it

Bought this for my teenaged son. He loves it. It pairs easily and has pretty decent sound in a small form factor. It's definitely waterproof and rugged and I never worry about him taking it outside or carting it around. He's had it now for over four months and haven't had a problem with it. The battery life is as long as advertised and the fact that you can pair multiple devices ended up with me borrowing it over the holidays since my speaker isn't wireless.

This is a shame because it should be a perfect 5. Everything is exactly what I wanted. Except that when paired to my phone on bluetooth, the speaker will turn itself off every ten minutes or so. It is highly annoying and a huge pain to have to turn it back on and re-pair it every couple of minutes. I bought this to use in my car and it completely defeats the purpose when you still have to reach around and turn the speaker back on every 10 minutes.

Nice sound (not perfect, but nice enough), beautiful packing box, excellent product so far. I'm thinking in buy another one.---Updated two months after buying it:Using it at shower, the charging compartment does not close very fit, so water started to enter into the speaker. Obviously, it stopped working and after that I bought an Arespark AS200 B00WE48SN6 Arespark AS200 Outdoor Bluetooth 4.0 Speaker (Black) The Arespark AS200 has two better features for me:1) Better water proof compartments2) When using TF Card, the AS200 remembers last song played, so it does not play from the 1st song every time (the Youmoon did that, so I got bored of listening the same song and song order, every time I used it )
