Ultimate EarsBoom 4 Portable Waterproof Bluetooth Speaker with 360-Degree Immersive Sound, Outdoor Floating Speaker, 15-Hour Battery, 147ft Range - Black

Ultimate Ears portable speakers are the best on the market.My original one from 10 years ago still works perfectly, sounds amazing, and the battery still powers the thing for like 8 to 10 hours on a full charge. I use it 2-3 times a week for many hours at a time.I’ve even taken it on multiple inner tube float trips (in a ziplock bag). I’m the most popular guy on the river. I’ve gotten enough free beer to pay for the damn thing.I clean it a few times a year with a damp rag and a shop vac and it still looks brand new, except for some minor polishing on the rubber over power button.I bought the UE Boom 4 to pair with the old one for stereo sound.It’s incredible. The sound is amazing!If this thing holds up like the original, I’ll probably never need another portable speaker.Except, I’m probably going to buy 2 more to have surround sound stereo wherever I go and whenever I want it.Can’t say enough good things about this company and their products.Buy one. You’ll love it.

Excellent sound quality, battery last longer than many other brands I've used and it's pretty resistant.

Excellent deal for a powerful speaker ! Love it !

Purchased for Father's Day. My dad loved it. It provides decent volume for its size and crisp, high quality sound. The only thing to note is that it comes with charging cable but not box to connect to outlet.

It's a great speaker if you're a podcast listener. Sound and quality are top notch. However it fails when it comes to music. There is absolutely no bass. If you're like me when it comes to music, buy a bose.

Great sound from a small footprint. Charge lasted most of the day.

This is by far honestly probably one of the worst speakers, and worst investment into a speaker, that I’ve ever made. I understand if maybe I got a faulty speaker, maybe the internals are just not properly set up and I just can’t see it. I will say though, total waste of money. I spent $150 on a “high quality” speaker, that’s got choppy connection to the device playing music, and it has YET to last me longer than 3 1/2 hours even being charged for 8-10 hours at a time. Wouldn’t recommend to anybody honestly, again, unless my speaker is just malfunctioning. I do not like leaving bad reviews, I love to support the companies I support by buying their product, I’m just absolutely as dissatisfied as I could be in full honesty. Expected so much more. Not sure I trust to buy anything from this company at this point. Used to be good, everything collectively seems to be going downhill.

The speaker works great. I love the smaller size especially for traveling. The color also pops. Great sound quality.
