Our Verdict
The Bose S1 Pro Plus is fair for music. This speaker is designed with musicians in mind, offering many connectivity options for microphones, guitars, and more. The three-channel mixer and other features let you adjust the sound of these instruments accordingly, which is a cool touch. If you just want to listen, you can always pair up a smartphone to stream audio wirelessly. With a balanced sound out-of-the-box, voices and lead instruments clearly and accurately reproduce. Its Auto EQ tool ensures you get the best sound no matter how you position the speaker. It can't bring the deep rumble in the low-bass like other premium speakers.

The Bose S1 Pro Plus isn't designed for watching movies, but if you want to watch a video from a paired smartphone, it can get the job done. There's relatively low latency with iOS and Android devices, so there aren't any lip-synching issues with dialogue-heavy videos. Voices are reproduced with clarity, too, so it's easy to follow along with the conversation. This speaker doesn't bring as much thump and rumble in the low-bass as other models, so you don't get a very cinematic feel with action-packed content.
