    Doesn't use app like previous versions. Great sound quality a little tricky to use in stereo pair.

    These little speakers are amazing!! Easy to hook up and they sound like a much larger than they look. Saved hundreds, if not thousands by going with these instead of permanent speakers

    It’s super portable, battery lasts, and it says it’s waterproof. I haven’t tried submersion, but it’s been splashed a little, hahah. At this price point, it sounds great. No regrets.

    I use my WONDERBOOM 4 in the backyard when I garden. It has a nice smooth sound and when I turn it up, the neighbors across the arroyo can hear it. I play jazz, classical, and salsa. For the size and money, it is great.
