Small but powerful. Buy it if you are a music fan.
Color: Blue
Bought it for my husband. He has about 7 speakers. I bought this one because of the size and the water resistance feature, we were going to a cruise. To my surprise it is small but powerful. He loves it. It is a great brand. The sound is great. He carry with it all the time. Is the only speaker that he uses and always tells his friends to buy one. He says he is going to buy another one because you can link them and do a surround sound experience. The battery life is out standing. The speaker color is joyful and overall is a great buy. ... show more

No Subscription needed for app, Decent sound if you place right. Great portable speaker!
Color: Black
This is exactly what you'd expect from a palm sized speaker system! It's lightweight, portable, has great battery life, an app that gives you access to battery life and even equalizers! It sounds decent enough for it's size due to it having two dedicated speakers to output different frequencies. Bass is lacking, but that's to be expected, this isn't a sound system, it's a portable speaker. Note: If you place it in a corner, or an open container, the sound will magnify. I tend to place mine on the package of toilet paper rolls when I take a shower, because it makes the whole room reverberate. Quality build, with a polyester type mesh surrounding the entire unit (added water retention / speaker protection) and matte rubber bumpers on the base and the side, for face up or side facing speaker orientation. Easy to use button system, quick Bluetooth pairing. No subscriptions for the app, free to use. Type C charging, and has a heavy duty mesh loop on one corner of the unit for hanging it places, around your neck, from a ceiling hook, anywhere you can attach it to! This speaker is supported by JBL Aura Cast, which allows you to pair multiple speakers at once and simultaneously play audio through the system you've created, so you can buy multiple speakers or even other speakers sold by JBL and pair them, have this one in the bathroom or kitchen playing the same audio as in the office or living space! ... show more

Amazing speaker for yourself or as a gift!
Color: White
I got this as a gift for my girlfriend to match my own JBL go flip 4 and she loves it! After having it for a year there are no sound quality changes, it connects to phones/laptops very easily and is super small. I personally have the black one but my girlfriend loves the white one so you can’t go wrong! The controls on the top are nice to have the volume adjusters but I don’t find myself using them all that often. This JBL speaker was one of the cheaper ones on Amazon that I found and it did not disappoint at all for portability, sound quality, and price. ... show more

A Sound Choice… get it? lol
Color: Purple
I use this speaker often. While I cook, clean, shower, and when my kids and I go out in the yard for fresh air. Connected easily with my iPhone. Doesn’t shake the windows but loud enough. I think it was a good price. I like the purple color. Battery lasts pretty long. I can go a few days of frequent use without charging but probably couldn’t last all day. Came with a guide for the buttons but it’s simple. Small enough to throw in my purse for when we go to the beach. ... show more

Decent for rain sounds
Color: Black
I was looking for a speaker for rain sounds to drown out noisy neighbors. The audio randomly gets kinda muffled sometimes and there's no way to see how much battery it has so it sometimes it will just die cause I hadn't charged it recently enough, but it's small, portable, and otherwise reliable, so I'm happy. The bass sounds good on the thunder and the rain sounds real enough to put me to sleep (I selected specific videos to test this). ... show more

Big sound in a small box
Rugged and great-sounding speaker that just works. Simple to configure and control for big sound anywhere. It's also a good-looking little unit with a lot of color choices to fit most tastes. USB-C connection makes charging simple, and the battery really does last as advertised. The controls are easy to access as well, with large clearly-visible buttons. The ease of pairing for stereo is a big plus, and I'm planning to get a second unit for that purpose. ... show more
