Additional Features
PureVoice 2.0
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.
Works with all ecosystems and music streaming services
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.
JBL ONE App
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.
Works with voice assistant-enabled speakers
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.
Made in part with recycled materials
The JBL Bar 300MK2 incorporates post-consumer recycled plastic and recycled aluminum. It is also packaged in FSC-certified paper printed with soy ink.
SmartDetails
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.
Easy sound calibration
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.
HDMI eARC with 4K Dolby Vision passthrough
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.
Deep sleep
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.
