JBL Authentics 500
Ranked #4 in Best Waterproof Bluetooth Speakers
JBL Authentics 500
$559

The JBL Authentics 500 blends retro aesthetics with modern streaming capabilities, featuring a 3.1-way speaker system with a 6.5-inch subwoofer. Hifi Pig praised its ease of setup and feature-rich app, while Sound Advice reviewer Carrie-Ann Skinner noted the speaker's premium feel and nostalgic design elements. However, some reviewers found the bass response to be overly prominent without adjustment. This speaker targets casual listeners seeking a stylish, versatile home audio solution rather than audiophiles.

Strengths
  • — Retro design with textured leather-like vinyl wrap and signature Quadrex grille
  • — 3.1-way driver configuration with 6.5-inch down-firing subwoofer for deep bass response
  • — Supports dual-band WiFi, Bluetooth 5.3, and multiple streaming protocols including Spotify Connect and AirPlay
Watch-outs
  • — Bass can be overbearing without proper placement or EQ adjustment
  • — The Quadrex grille may be polarizing due to its distinctive angular design

How they stack up

Bose SoundLink Flex (2nd Gen)

The Bose SoundLink Flex offers a rugged IP67 build and improved control strip, but lacks the EQ customization of the JBL Charge 6 and the advanced features of the JBL Boombox 4. Compared to the Soundcore Boom 3, it provides better sound quality and durability, though it has minimal upgrades from its predecessor. Unlike the Bose SoundLink Max, it's more affordable but lacks powerful bass and call functionality.

JBL Authentics 500

The JBL Authentics 500 brings premium streaming features and a retro design that sets it apart from the JBL Charge 6 and JBL Boombox 4, which lack Wi-Fi and Spotify Connect. While the Bose SoundLink Flex and Soundcore Boom 3 offer simpler designs, the Authentics 500's 3.1-way driver configuration and physical controls make it better suited for audiophiles seeking a stylish home speaker. It's less portable than the portable models but more feature-rich for home use.
