This tiny powerhouse fits in the palm of your hand, but can get as loud as a larger speaker without losing much clarity. The fourth-generation speaker has less muddiness than the previous one, especially at higher volumes, as well as an Outdoor Boost Mode and Podcast Mode. Plus, it has a new USB-C port for easy charging. Otherwise, it's pretty much identical to the Wonderboom 3 (which we also loved). Like its predecessor, the Wonderboom 4 can survive drops from up to five feet and plunges into water for up to 30 minutes (thanks to an IP67 rating). It also packs a healthy battery life of 14 hours.
