Loud, bassy beast; needs EQ, no aux.

I actually had Onyx 3 and Go Play.
I love my HK Onyx 3
Harman kardons onyx studio series are made exactly for that
Harmon Kardon Onyx Studio the original one. Bought mine 2013 refurbished on eBay and it’s still going. Bought a replacement battery and it was super easy to replace.
HK Onyx Studio, thank me l8r.
Yeah, both the HK Go+Play and Onyx Studio series would blow away the Max. They are my go-to speakers when I want the music to really shine through. Incredibly deep bass and crystal clear mids and highs. None of my other 5 portable Bluetooth speakers come close. Edit - Just saw someone post the HK Go+Play 3 is selling on ebay for $132 right now. At that price, it's a no brainer.
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.
If you're "upgrading", go to the next level.. not the same speaker in a different housing. Look for a used HK Studio Onyx. Pick the style you like the look of and hear your music in a truly upgraded fashion. Even the 10-15 year old ones still sound awesome. The HK Go+Play series is just as good too. Either one will blow you away over what you had.
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.
