The JBL Flip 6 is a noticeable improvement over the Flip 5. The rubber accents on the edges of the speaker have been toned down, and the passive bass radiators now feel cool, textured and metallic. The layout of the power and Bluetooth buttons next to the USB-C port remains unchanged, but they are on a smaller rubber plate that no longer spans the entire length of the speaker. ..

The Flip 6’s stability has been improved with the addition of a small rubber foot under the panel to prevent it from tipping off the desk. Previously, the speaker’s fabric jacket connection point was hidden by the larger rubber plate, but now it is fully visible. The Flip 6 also has an advantage over other JBL Portable speakers thanks to Partyboost buttons on the app which allow you to find and pair other JBL Partyboost-enabled speakers in “party” mode or stereo. ..

The Flip 5’s stereo sound is good, but not great. The three-band equalizer on the in-app dashboard makes it better, but it still isn’t perfect.

The JBL Xtreme Portable Bluetooth Speaker is a great option for bass lovers who want to increase the bass output without sacrificing other frequencies. The speaker is roughly the size of a hotdog and has three sliders to adjust the bass, mid, and treble frequencies. ..
