JBL Authentics 300 delivers superb sound and performance, filling any room with rich stereo audio. It features a pair of 1-inch tweeters that highlight the finer details in your music, while a full-range 5.25-inch woofer and a down-firing 6.5-inch passive radiator provide deep, balanced bass. These premium components ensure a perfectly tuned sound experience, no matter the genre. Inspired by classic JBL retro designs, the Authentics 300 blends vintage charm with modern functionality. Its custom leather-like enclosure, reimagined Quadrex grille, cast-aluminum handle, and subtle JBL signature pattern on the passive radiator all reflect meticulous attention to design, making it a stylish addition to any space—large or small.

This portable speaker is equipped with a built-in battery that offers up to 8 hours of playtime, so you can enjoy music on the move. With built-in Wi-Fi, you can stream everything from high-definition podcasts to internet radio without interruptions—even if you leave the room or take a call. It supports AirPlay, Alexa Multi-Room Music (MRM), Chromecast built-in™, and Spotify Connect, and receives automatic software and feature updates to stay current. The Authentics 300 also supports both Google Assistant and Amazon Alexa simultaneously, giving you hands-free control over smart home devices, music streaming, and more—using the voice assistant of your choice.

Bluetooth pairing is seamless, allowing you to easily share playlists from any device. On-speaker controls let you adjust volume, bass, and treble, while the JBL One app offers further customization options, including EQ settings and integrated music services for discovery. For whole-home audio, you can place multiple Authentics speakers throughout your space and use the Google Home or Amazon Alexa app to sync them to a single playlist for multi-room playback. Wherever you take it, the speaker automatically calibrates and optimizes its audio output to match its surroundings, ensuring great sound every time it’s powered on.
