Hear the sound come alive

You’re watching TV in 4K high definition resolution—so why listen in black-and-white? Flat TVs only offer flat sound. The JBL Bar 300MK2 delivers immersive, cinematic sound worthy of our almost century-long Hollywood heritage. Whether you're watching or gaming, enjoy crystal-clear dialogue, Dolby Atmos® surround effects, and a wide soundstage that elevates your entertainment experience. Plus, easy access to hundreds of streaming services, so you can groove to your favorite music with best-in-class sound all night long. All from a smartly designed soundbar that's perfect for cozy rooms and works with every brand of TV. Hear the sound come alive.

Get a truly immersive sound experience from your music, movies, and games with 450 watts of max output power. Feel the thrilling energy of your favorite music and movies from built-in bass ports that pack a powerful punch.
Hear a plane soar overhead. Feel a crowd swarming past you. Or get carried away by the energy of your go-to dance playlist. Hear extraordinary cinematic sound from all directions with the 3D audio experience of Dolby Atmos®.
Wherever you're sitting, you'll be in the middle of the action. Our MultiBeam™ 3.0 delivers a wide, cinema-like soundstage that makes every high-speed chase or epic fight scene come alive. The sound beams perfectly fill your room, delivering truly immersive, lifelike, and realistic sound reproduction.
Never miss a softly spoken line or a whispered plot twist. JBL's own PureVoice 2.0 automatically raises or optimizes the dialogue, based on both ambient sound in the scene and your soundbar's volume. So you'll always hear every word, clearly and consistently, in cinema-quality sound.
Hear all the subtleties in a film's sound mix, just like you would in the theater. From a creaking door to a faraway shout, experience every detail the way the filmmakers intended in a clear, balanced sound field, thanks to JBL's own advanced sound enhancement technology.
Enjoy all your favorite music and podcasts in stunning high-definition sound. Choose from hundreds of online music streaming services through AirPlay, Google Cast, Spotify Connect, Tidal Connect, and Roon Ready.
Every room is different. Your soundbar discovers how sound reflects off your walls and furniture. So it'll deliver the best 3D surround effects, tuned specifically for your space and with any TV.
Set up the soundbar using the JBL ONE app, then make it yours. Customize the sound your way with a precise equalizer, browse your favorite music apps, and get software upgrades for all the latest features, right from your couch.
No matter what brand your TV is, enjoy uncompressed Dolby Atmos surround sound through a single HDMI cable thanks to the HDMI eARC connection. The HDMI input connection also offers 4K video quality from a compatible video player or gaming console.
Play that song you're craving, even when you've got your hands full. Just link the soundbar to your device with built-in voice capabilities and control your music hands-free using Google Assistant or Siri.
When you're asleep, so is your soundbar. It uses less than 1 watt of power while in standby mode. That's about the same as your TV's remote control.
