Unlike a couple of others who posted positive experience with this item, my experience was pretty bad. It worked fine for a few weeks. Then, inexplicably, it started making a repetitive droning sound, sort of like an engine hiccuping (dzhuh, dzhuh, dzhuh, dzhuh, dzhuh, etc.). It would not turn off and the volume buttons didn't work. I could find no reset pin (nor any reset instructions in the very sparse "documentation" included with the speaker). So, I returned it. For a day and a half, until I could get a chance to return it, it constantly made this annoying sound - I repackaged it and had to put it in the oven in order to minimize the sound!

This is my speaker of choice. Waterproof is a bonus. It's not enough for a full outdoor party environment, but it is definitely able to fill a room with quality sound while being the size of a softball. It has long battery life.

I personally would never buy anything from Uline, but when I'm doing the ordering for the company that does need supplies, well then, it's free for me.

Free is a stretch considering you had to spend $1,500 or more to get it

I have three of these. They're easy enough for my wife and kids to figure out without having to set them up. Not to brag, but I got all of them for free (Uline freebies)
So I have a WonderBoom 2, do you know if these would pair up, or do you need the same version?

I have connected the 2 with the 4 and they worked together. The only difference I found between the two models is the USB connection. Micro vs usb-c.

Quote from CheapskateNate :
I found the WB4 to be pretty mediocre and returned it. At this price, I'd recommend either the Tribit Stormbox Micro 2 or the Earfun Uboom L, both of which can be had for ~$50. www.speakerranking.com has the Wonderbooms ranked around 80th for medium sized BT speakers.
Lol careful now. Any time you go into a popular Bluetooth speaker brand post and suggest other great options, you are rolling the dice with whether or not you will catch some retaliation from the loyal lol.
I will 2nd the recommendation for the Tribit Stormbox Micro 2. I have was too many Bluetooth speakers (according to my wife) but the ones that have been grabbed most frequently for a variety of scenarios over the years have been the Micro 2 and the Soundcore Motion+. A lot of speakers have entered my rotations but those two have stuck around
