Our Verdict
Ultimate Ears WONDERBOOM 4
Sony LinkBuds Speaker
Though similarly sized, portable speakers, the Sony LinkBuds Speaker and the Ultimate Ears WONDERBOOM 4 are meant for different purposes. The Ultimate Ears is a great choice for the outdoors. Its 360-degree design means audio sounds very similar from whichever angle you're listening, and it's rated IP67, so you can drop it in a puddle without damage. It also gets a bit louder than the Sony. On the other hand, the Sony has a great built-in mic that you can use with your phone's Siri, Alexa, or Google Assistant, and it also comes with a companion app that you can use to tweak its sound to your liking,
