Product Information

Made for everyday - and everyone. The new Bose Smart Soundbar 300 delivers spacious sound, clear dialogue, and rich bass for your movies, music, and games. The acoustic architecture is specially designed to keep this soundbar sleek and elegant. With built-in voice assistants and exclusive Bose Voice4Video™ technology, what typically takes several steps can now be done with one simple voice command. It’s fast, simple, and easy enough for everyone to enjoy. 

Spacious sound

With four full-range drivers, a center dome tweeter, and two ports, this smart soundbar is built to deliver spacious, clear dialogue and rich bass to get you completely absorbed in your favorite movies, shows, music, or games.

Clear dialogue

By analyzing what you’re watching, elevating center vocals, and boosting the treble, the Bose Smart Soundbar 300 lets you hear and understand every word clearer than before.

Say it. Watch it.

Bose Voice4Video™ technology lets you expand your Alexa voice capabilities like no other soundbar can. In addition to controlling your Bose Smart Soundbar 300, you can control your TV and cable or satellite box with just your voice. Turn on your TV and jump to your favorite station all with one simple ask of Alexa. Just say, “Alexa, watch the NFL Network,” to start watching instantly.

At your command

With Alexa and Google Assistant built-in, you can control all your entertainment, manage your day, and get information — without lifting a finger. The noise-rejecting microphones of Smart Soundbar 300 work together to listen in every direction for your command, even when the music’s playing loudly. And for extra privacy, you can disable the microphones anytime with the mic-off button.

The soundbar for music

Wirelessly stream whatever you want, however you want. You can connect directly with a device via Bluetooth®, or through your home network with Wi-Fi®, Apple AirPlay 2, or Spotify Connect. Play your favorite music services, like Spotify®, Amazon Music, or Apple Music, or anything from your phone or tablet.

Listen, however you like.

Bose SimpleSync™ technology allows you to connect your Bose Smart Soundbar 300 with other Bose products. Want to watch TV but not disturb anyone else? Connect your soundbar with a pair of Bose Headphones 700, Bose QuietComfort Earbuds, or Bose Sport Earbuds for a personal TV listening experience. Want to listen to the same music in two rooms? Connect your soundbar with a Bose Bluetooth speaker for more sound in your home.

Music in more rooms

The Bose Smart Soundbar 300 is part of a family of speakers and soundbars that is designed to grow with you, so you can enjoy more music in more rooms.

Control your experience

With the Bose Music app, you can easily browse through all your music in one place and seamlessly jump between stations, playlists, and services. Plus, it’s another simple way to control the Bose Smart Soundbar 300, allowing you to group products, set up presets, and get a personalized experience for multiple users.

Easy to set up. Easy to use.

The Bose Smart Soundbar 300 uses a single connection to your TV via an optical audio cable (included) or an HDMI™ cable (sold separately), so you can go from unboxing to watching in minutes. The soundbar will detect a signal from your TV when turned on and automatically turn on, too. And when connected with HDMI, you can keep using your current TV remote to control the volume.

Compact size

This elegant and compact soundbar stands at just 2.25″ (6 cm) tall and is designed to fit perfectly under any TV. The top surface has a sleek black matte top, complemented by a perforated wraparound metal grille.

Want to kick it up a notch? Add more.

You won’t believe what the Bose Smart Soundbar 300 is engineered to do on its own, but we have more whenever you’re ready for a boost. Add a Bose Bass Module for room-rocking bass. Or combine it with Bose Surround Speakers for full-on surround sound that puts you at the heart of the action.

The soundbar for sports

You don’t just want to watch the game. You want to hear it — loud and clear. The playcalling, the commentary, the touchdown celebrations. As the Official Soundbar of the NFL, the Smart Soundbar 300 is the next best thing to being there in person. Ready. Set. Game time.

Great sound quality
After a lot of research and deliberation, I settled on the Bose 300 Soundbar. I'm very happy with this choice as you can't go wrong with any Bose speaker. The sound is crisp and clear. The only complaint I have is that I cannot make it work with Alexa the way I wanted to. Alexa doesn't seem to recognize it as a speaker and puts it in the TV category so you can't use it as part of a "group" to play music from. Instead, it works independently. Meaning you can play music out of it using Alexa, only if you use it separate from your other Alexa devices.

Good product
I bought the soundbar last month. It’s very good but I was surprised that in a way to connect the bass I need to buy additional cable. This was a little disappoint.

Great Sound but continues to disconnect from TV
Received as a gift and set it up with HDMI ARC. I have. A 2year old Sony 65” TV and every once in a while the unit disconnects from the TV sound and I have to unplug and replug in the power to get it back. ALEXA works fine except when it disconnects. Once that happens the Bose remote no longer works and the Bose app doesn’t connect either

Pretty basic. Like, having an on and off switch. Guess I expected more clarity on dialog and a “Bose” sound. Will probably send this back.
