Retro Soul. Modern Intelligence. Wireless Freedom.
If you’ve ever wanted the warmth of vintage audio design with the intelligence of modern streaming, the JBL Authentics 300 hits that perfect sweet spot.
It’s not just a Bluetooth speaker — it’s a piece of art that sounds as rich as it looks. Wrapped in classic black and gold with JBL’s signature grill pattern, this speaker brings old-school charm and new-age power into perfect harmony.
Powered by a 4800 mAh battery, dual voice assistant integration (Alexa + Google Assistant), Wi-Fi and Bluetooth streaming, and the unmistakable JBL Pro Sound, this is a speaker that travels from your living room to your terrace without missing a beat.
- Superb sound and performance: Fill any room in your house with stereo sound. The 25mm tweeters bring out the details in your music, while the full-range 5.25” woofer & 6.5” passive radiator deliver deep bass, ensuring you’ll get the perfect audio balance.
First Impressions – Retro Done Right
The moment you unbox the Authentics 300, the nostalgia hits.
The design feels inspired by JBL’s iconic heritage — the metal frame, the textured grill, the gold-accented knobs — but there’s nothing outdated about it. Every surface feels premium, tactile, and thoughtfully finished.
Pick it up and you’ll notice the satisfying heft. It’s solid, beautifully balanced, and reassuringly durable — exactly what you expect from JBL’s premium range.
Once powered on, the front LED softly glows, and that first sound check delivers deep, confident tones that instantly fill the room.
This isn’t a speaker trying to be flashy — it’s effortlessly classy.
Sound Quality – Authentic JBL Warmth, Elevated
Underneath the timeless exterior lies serious acoustic engineering.
The Authentics 300 houses high-performance JBL Pro Sound drivers, engineered for clarity, precision, and room-filling depth.
Bass hits warm and full — not boomy, not artificial. The midrange is beautifully balanced, and the highs sparkle without ever feeling sharp. Vocals sit right in the sweet spot, giving you that “live performance” realism that JBL fans love.
You can easily adjust the EQ via the JBL One app to fine-tune the output to your taste — whether that’s cinematic depth, crisp podcast clarity, or an intimate acoustic soundstage.
It doesn’t just play music — it performs it.
Wireless Freedom – Wi-Fi, Bluetooth, and Beyond
The built-in dual connectivity makes this speaker as flexible as it is beautiful.
Connect over Bluetooth when you’re on the go, or use Wi-Fi streaming when you’re at home for lossless, uninterrupted sound.
Thanks to AirPlay 2, Chromecast, and Spotify Connect, you can stream directly from your favorite music platforms without even touching your phone.
And because it supports multi-room audio, you can sync it with other JBL Authentics speakers or compatible devices to create a house-wide sound experience that feels cinematic.
No drops, no lag — just seamless, immersive sound everywhere you go.
Smart Features – Alexa and Google Assistant, Built In
This is where the Authentics 300 pulls ahead of most wireless speakers.
It’s the first JBL speaker that lets Alexa and Google Assistant work side-by-side — no switching accounts, no toggling modes.
You can ask Alexa to start a playlist, then ask Google to check your calendar — all without lifting a finger.
Voice control works flawlessly even with music playing, thanks to the far-field microphones built into the top.
And with built-in Wi-Fi, voice commands feel faster and more responsive than Bluetooth-only assistants.
It’s as smart as it is stylish.
Portability & Battery Life – True Wireless Freedom
The 4800 mAh built-in battery gives you around 8 hours of wireless playback — enough for a full day’s music, movie night, or backyard party.
The built-in leather-style handle makes carrying it effortless, and because the power supply is universal, it’s just as comfortable being a travel companion as a permanent home fixture.
It’s a rare speaker that feels equally natural on a kitchen counter, garden table, or road trip trunk.
Everyday Experience – The Blend of Form and Function
After a few days with the JBL Authentics 300, it stops feeling like a speaker and starts feeling like a companion.
Mornings begin with smooth jazz in the kitchen via Wi-Fi streaming.
Afternoons become soundtracked by playlists as you carry it out to the patio.
Evenings wind down with low-volume podcasts and soft ambient tracks — still rich, still warm, still JBL.
It never demands your attention; it just delivers consistent, soul-pleasing sound.
Pairing is instant, the JBL One app offers granular control, and switching between voice commands or devices feels effortless.
Everything just works — which is exactly how premium should feel.
