Our Verdict
The Bose S1 Pro Plus is decent 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 a smartphone to stream audio wirelessly. It has a warm sound, with some extra high-bass that adds fullness to guitars but can also make voices sound a bit muddy. Still, its balanced mid-range ensures you sound intelligible. That said, it doesn't produce much low bass, so it's not the best speaker for dance music events.
- Lots of connectivity options for instruments.
- Gets loud.
- Some compression at max volume.
- Lacks some low-bass.
The Bose S1 Pro Plus is acceptable for videos and movies. 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 much thump and rumble in the low bass, though, so you don't get a very cinematic feel with action-packed content.

- Auto EQ feature to optimize sound.
- Some compression at max volume.
- Lacks some low-bass.
The Bose S1 Pro Plus is very good for podcasts. You can easily stream audio from your mobile devices to the speaker via Bluetooth or connect your phone over an AUX input. Its balanced mid-range ensures voices reproduce clearly, so you can follow along with the conversation in your favorite shows. Since it gets remarkably loud, too, you can crank up the volume when you listen in larger rooms. Plus, the Auto EQ feature automatically optimizes the speaker's sound based on its position in your room, which is a cool touch.

The Bose S1 Pro Plus is a decent choice for playing music outdoors. While it isn't rated for dust or water resistance, it boasts a sturdy build with a built-in handle for easy transport.
