RICH SOUND & WATERPROOF
Was looking for a portable speaker that could take being used while gardening and this is the ONE!. Bought one for my husband (black) and he tucks it into his golf bag plus one for me (hot pink so I can find it in the yard easily). Like that it is waterproof, so if I forget to bring it in and it gets wet- still works. Very rich sound even at high volume. Its a little bubble of a speaker with long battery life, light weight for how much sound it puts out. Charges quickly. Took it out of box and started using right away with no problems pairing with both of our phones. Easy instructions. Comes with a charging cord. It was on sale. Much less expensive than my Bose which I have had for several years and a better sound and longer battery life. Built like a tank. Has held up to being dropped, left outside overnight.

Great purchase. Full stop.
I own lots of blue tooth speakers of all sizes…for travel purposes this speaker is completely on point. Lightweight, however punches well above average for its size. Connectivity is solid, instant and hassle free. This is the third ultimate ears speaker i own. Bravo, well done!

Great speaker for those with hearing issues!
I have only been using this speaker for a few days but am so impressed with the quality of the sound. I have a hearing disability and yet find the clarity and ease of hearing to be phenomenal. Also, the ease of use is excellent-set up and navigation.

Love it!
This is my second purchase, the first one still works great after approximately 5 years, I needed a second one for another location. The sound is great, it works well, great value, charges quickly, easy to use, and it's a convenient size.

Great portable speaker
I use this to play audiobooks while I golf and this is perfect for it. The sound quality is great. The handle is a spandex material, so it can be looped around one of the hooks on my bag and it's very secure. Very happy overall.

Where is the strap??
The sound is great, the bass is strong for such a small speaker and I guess that’s all I should be rating it on, but it’s impossible to ignore the poor ergonomic shape of this speaker and the fact that they didn’t include a strap to attach to the pathetic loop on the top. The lop is not even big enough to fit your finger into so carrying this softball sized speaker requires the undivided attention of one of your two hands. Had this had an included strap so that I could loop it around my wrist or finger and free up my hand I would have given it five stars.

Amazing
Best speakers I've owned. I heard them first from a coworker in person and was immediately sold. Listening outside I didn't realize my co worker had only had 2 speakers going. It sounded like the music was all around me, impressive for just 2 stereo speakers.

Great buy
The sound on this bad boy is amazing. For the price, it’s a steal. Pairs easily and looks cool too.
