Ranked #4 in Best Waterproof Bluetooth Speakers

2 sources$129as of Aug 1

The Bose SoundLink Flex (2nd Gen) keeps the durable, waterproof design of its predecessor and makes minor improvements to the control interface. SoundGuys praised the rugged build and IP67 rating and called it a good match for outdoor use, while noting lackluster EQ options and minimal hardware upgrades from the original. A TechRadar user pointed to its day-to-day reliability and portability. It's a solid choice for anyone who wants a dependable portable speaker for travel or outdoor activities.

Strengths
  • IP67 rugged build for dust and water resistance
  • Durable rubberized finish with metal speaker grill
  • Improved control strip with dedicated Play/Pause button
Watch-outs
  • Lackluster EQ options
  • Minimal upgrades from 1st Gen

The JBL Authentics 500 wraps a Wi-Fi streaming platform and a 3.1-way driver array in a retro wood cabinet, and it plays loud and deep enough to fill a living room from a single box. TechHive rated it 4 out of 5, praising the sound while flagging the bulk and the price; 7Review, at 9 out of 10, was far less convinced by the midrange and found the bass compressing at higher volumes. It is a stylish, feature-complete home speaker rather than a reference listening device, and it will not pair into stereo.

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.
