Durable and Quality sound
Midrange sound quality but the Bluetooth speaker itself is tough as nails. Able to be thrown in a pool and is waterproof.

Great little speaker
Completely portable. The battery lasts forever! Good sound but could be louder (I am an ‘80s Hi Fi music nut, This thing is probably just fine for regular people). We use it in our side by side since it came without a radio. Have even taken it hiking playing Christmas music while Christmas 🎄 tree hunting. Bluetooth hooks up quickly and easily to every device we have tried. 30 to 40 yards is about its limit. ... show more

Pro: Get VERY loud. Con: distort when too loud
These certainly get LOUD. Which is their main selling point. They also can get quite bass-y but once you go too high up in volume, they will certainly start to distort. In terms of audio clarity, they could certainly be clearer. this speaker is very mid-heavy. Comparing these to the Bose Soundlink II, these are muddier and bass is a lot looser. I found myself increasing the treble EQ in the UE app almost all the way to get clearer audio. But I found myself picking these over the bose because I would mainly use these in gatherings, which certainly excel because of their loudness. ... show more

Great speaker!!
The best purchase I have made in a while! Great speaker! A+++ Bluetooth connectivity works great, and the app makes it even better. Great sound quality! You can clearly hear all parts of the music no matter what you like to play. From soft rock, to pop, and yes, even Cardi B sounds good on this speaker. One great thing is that it does not distort at high volume. It is extremely durable and it really is waterproof ( it even FLOATS for those who might use it by the pool or at the beach). The battery life is great. I used it on maximum volume for an entire 8-hour day at the lake. After, I checked the app and it still had 34% battery left! The bass is smooth, punchy, and does not overpower the other frequencies. The design is beautiful, and the shape is ingenious (where my 32oz Hydroflask fits, so will the speaker). Bottom line: This is a perfect speaker to buy if you want durability, portability, great sound, cool style, and all-day battery life! ... show more

Faulty Product delivered twice in a row
The vendor sent me a faulty product. I have every intention to purchase this same product again, but there was a reason this was being sold for so cheap. Beware the deals that look too good to be true. To provide further insight, the product was shipped outside of its normal packaging. I applied power, and as soon as I turned it on, the speakers power button would periodically flash red and would not stop. Upon researching, this is an indicator of a fault. Factory resetting the unit did not help. Update: A replacement unit was sent by the vendor for no charge. Replacement was also delivered without manufacturers packaging, and was missing its charging block. Replacement was showing the same fault error when turned on (red flashing light), but went away after factory resetting two times. I'll use this for the day to see if the failure returns before deciding whether or not to return it. The replacement unit has some cosmetic signs of wear. I wouldn't make so much of a fuss over this if the unit had been sold as used, but Amazon/the vendor (I don't know who is to blame) is marketing this as new, and it is not. ... show more
