Soundcore Boost

For the money, the Soundcore Boost is the loudest and bassiest speaker available, easily contends with speakers in the +£100 market. IPX7 so perfect for the beach/pool side. Typically around £60 but often on sale for £40: [https://www.amazon.co.uk/Anker-Soundcore-Well-Balanced-Waterproof-Customizable/dp/B01N4V4X5M](https://www.amazon.co.uk/Anker-Soundcore-Well-Balanced-Waterproof-Customizable/dp/B01N4V4X5M)

Anker Soundcore Boost. Will fill a small room with mind boggling bass. Around 40 dollars on Amazon.

As you say your aging ears probably prefer a bright sound and more balanced speakers sound muddy for the same reason. Id pickup my soundcore boost before the flip 6 but its so warm you would find it unlistenable. Given your ears i wonder if you tried the motion plus?

I have two bluetooth speakers, both from Anker: a SoundCore Boost that I mainly use in my kitchen and living room with my laptop as a soundbar (Laptop speakers are tinny); and a SoundCore 2 in the bedroom and upstairs bathroom / shower, connected to my phone.

Not sure on US pricing however the Soundcore Boost may fit your needs, or the Motion 300 depending on how much that will cost you. 

I purchased JBL flip 6 and returned it after 2 days. It sounded a bit dull and mono. I had anker soundcore boost which sounded much better to me with deeper bass and smoother highs.

Dont know about others maybe they love that sound signature. But my anker soundcore boost sounded better to me and i have sound samples recorded earlier. Jbl does great in party speakers and boombox, but no so much in compact speakers.

Depends what music you listen to probably, I like the Soundcore Boost. Normally I listen to psydub, ambient, edm. It’s great imho for that genre.

I have an Anker Soundcore Boost bluetooth speaker. It comes with an app that allows you to adjust the eq AND turn off the annoying start up sound. It was under $50 us but seems to meet your basic requirements. I use it to listen to music at my office.
