Sony - SRS-XG500

I have a Sony ult 7, JBL bb3, Sony xv900, soundcore rave3s, Sony xg500 Sony xg300 Sony ult 5 Both ult1 for stereo  Soundcore boom 2 PRO (haters on that) Also boom3i  This motion x600 Drops bass low easily to 40 hz  My sonys drop to 20hz And JBL hits 35hz when plugged in  The x600 is super clean HIFI LIKE MY BIG SONY XV900 and SOUNDCORE IS NOT LACKING BASS. Seriously hifi sound with bass Real bass though  If the track doesn't have it It's not there  Great speaker  Seriously 💯 

I've had most of the lineup from JBL. The Go, Clip, flip, charge, extreme, and boombox. The only one I wasn't really happy with was the clip...it was being sold in a two pack and yet lacked the capability of virtually every JBL speaker which is to be able to link up to other JBLs and play in stereo. They're all good for their size/price. Obviously the Go doesn't thump like the boombox does but it's a fraction of the price and size. I think any of them up through the Charge can be charged with a USB cable then the bigger ones like the extreme/boombox have a proprietary charging cord. They're all at least somewhat water resistant and rugged all the way up to the Boombox and the Extreme being submersible. I remember when I first got the Boombox, being at a pool and my brother asked if I was worried about the speaker being so close to said pool. I said it's supposed to be waterproof and I then proceeded to throw it in the pool. It was totally fine. Battery life on them are all respectable, and at least personally, I haven't had a battery fail yet. The extreme and even more so the Boombox, seem to last forever. More recently I bought a Sony xg500 (Boombox equivalent) when it was on sale. Not a bad speaker, has good mids and highs, but the bass was a little lackluster and overall it couldn't get quite as loud as my 5 year old Boombox. It has an inferior IP rating compared to the Boombox as well. The only thing it really has over the Boombox, that I didn't even realize for a while, and it may or may not be a positive depending on the person, is it has some lighting effects on the side that strobe with music. Overall the Boombox is really the better buy for sure. The only other speakers I've heard that were as good or better were some bose ones, but they didn't have much bass, and the ones I saw didn't seem too rugged. The UE speakers I've heard were fine but not as good as JBLs

I have x600 and Sony xg500 , xg will be a good alternative and has unreal battery life .
