I've got 3 - a clip on my small disc golf go-bag, a flip (canister) on my main disc golf bag, and (not quite what is pictured here but) a Harman/Kardon Onyx 4 for home listening

my Harman Kardon Onyx Studio 4 is my baby. got it for like what.. $52 due to it having some paint marks on it (assuming doing remodeling and white paint dripped on it) plus missing charger.. got one for $10. so altogether $62 for an absolute gem, regardless of the weight or size, it is what it is. have yet to find a speaker that competes with it unless someone wheels in a fkn pa system lol.

The Onyx Studio series is in a class of its own. It’s the loudest most clear sounding bass portable Bluetooth speaker you can get at that price. I sold all my other “boombox” speakers and kept the Onyx. The Luna is nice, but it’s not in the same category. You’d need like 4 of them to match the Onyx.

My Onyx Studio is the best sounding speaker I have. Guarantee it blows away the JBL. You won’t find a better speaker than the Onyx unless you get something in the $600+ range.

I constantly see the HK G+P recommended here and after using one, I understand why. It’s a beast. Only matched by their Onyx Studio series. I hardly ever see any Sony recommendations.
