I’ve been testing the $269 Bose SoundLink Plus, which is the company’s latest portable Bluetooth speaker. The Plus is also about $100 cheaper than slightly larger options with more expansive features, like stereo speakers, Wi-Fi, or smart assistant integration. The SoundLink Plus is a mono speaker with a tweeter, four passive radiators, and a rear-facing subwoofer, which is expected for its price. The SoundLink Plus is approximately the same size as a 20-oz water bottle and falls between the SoundLink Max and SoundLink Flex (second-generation). The shortcut button can be assigned to either link two Bose Bluetooth speakers together or open Spotify.
