Bose SoundLink Flex (2nd Gen) vs SoundLink Plus

The Bose SoundLink Flex (2nd Gen) is a smaller, more portable option compared to the Bose SoundLink Plus. The two speakers perform similarly when it comes to sound, shaving off some bass but maintaining balanced mid and treble responses. You can adjust their sound profiles via the graphic EQ and presets in the app, though both speakers are limited to mono-only playback. The SoundLink Plus has a longer, almost 20-hour battery life. While the SoundLink Flex's battery life is only a third of this, you're faced with a less daunting 2.4-hour charge time (as opposed to 4.6 with the larger speaker). If you're a voice assistant user, you'll likely favor the SoundLink Flex, though, which can work with compatible voice assistants on your phone and has an excellent microphone.
