That's good to know. Can't wait to hear it. Ive had like 5 onyx 2s all over my house for like 10 years and they are still flawless.

Have you considered the Onyx Studio 9? I’ve had a Studio 2 for years and it still sounds great. The Go+3 is a great choice too - poor battery life though. If you’re leaving it plugged in, it shouldn’t be a problem. My Studio 2 has no battery left but it still works fine as long as it’s powered.

Soundcore motion boom is really good value, sounds decent and has a big battery. I wouldn't leave anything permanently on charge though. Onyx series of speakers can run either plugged in to their adapter or just of their (tiny) battery - at least the 2nd gen one which is what I have. I find it a bit too bass heavy fatiguing sound though, more so plugged in as the bass is boosted more running from the adapter. I have an IKEA bt speaker from a few years ago that either runs off the mains or battery pack, they may have a more modern equivalent. It sounded decent but not outstanding, although probably most of what you get of a decent size these days is probably going to be night and day compared to what he's got now.

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.
