Interesting. Since Sony, whose Bluetooth speakers I'd been using for most of a decade, discontinued most of their higher-end stuff, I tried out the JBL Charge 4 earlier this year and was astounded at how bad the sound quality was. There was a very ugly rumble in the low mids that was grating. I'd wondered if I'd gotten a defective unit since the sound quality was so bad, but was disenchanted enough to look elsewhere. From what you're saying, it sounds like they may have been another victim of the bass wars. I ended up going for the Anker SoundCore Boost, which I genuinely thought sounded better and is a third the cost.
