About this item

  • Superb sound and performance: Fill any room in your house with stereo sound. A pair of 25mm tweeters bring out the details in your music, while the full-range 5.25-inch woofer and down-firing 6.5-inch passive radiator deliver deep bass. These top-grade components ensure you'll get the perfect audio balance, no matter what kind of music you're listening to.
  • Inspired by retro design: The JBL Authentics 300 delivers iconic style inspired by classic JBL retro designs, in a portable home speaker that looks great in any decor. It will easily fill any space, big or small, with superior JBL sound. And the speaker's convenient cast-aluminum handle, custom leather-like enclosure, and reimagined Quadrex grille really show the attention we paid to each visual detail, right down to the special JBL signature pattern on the down-firing passive radiator.
  • Built-in battery: Keep the music going with 8 hours of playtime from a built-in battery and an integrated carrying handle that makes it easy to take your audio anywhere.
  • Music streaming services via built-in Wi-Fi: Experience everything from podcasts to internet radio in stunning high definition. Or stream music through AirPlay, Alexa Multi-Room Music (MRM), Chromecast built-in, and Spotify Connect and leave the room or take a call without the music being interrupted. The Wi-Fi connection ensures your speaker gets automatic software and feature updates.
  • Voice assistants*, simultaneously on one device: Google Assistant and Amazon Alexa are available simultaneously*. This gives customers the most freedom and convenience to control more smart home devices, play from more music streaming services, and get the most hands-free help from either voice assistant at any given time.

jadedreviewerJune 21, 2025

It requires a ton of fine tuning and still can't get it to sound accurate. It's so base heavy and boomy. The only reason I bought it is because it works with Google chromecast. If I had time I would return it and find something different Read more
