I'm Geezer First Class (80) and would like a bluetooth portable speaker but many I've seen online and heard in person all tout their special bass kick, etc. I need the opposite. I have always had trouble hearing high frequencies and now it's worse than ever. Most stuff sounds to me like it's coming through a couple of pillows. Would dearly like to hear less bass, more treble. I chatted online with the robot at one dealer and it suggested that I use the Equalizer on my phone but that only gives you preset choices, like: Lounge, Latin, Pop and such. Sure, it has "Treble Booster" but I hear no difference. I need treble blaster. And you can choose "Treble Booster" or "Bass Reducer" but not both. Is there any way to get an actual EQ panel with sliders or a speaker without bass?
