That explains it I have mine at work and don't always use it and thought my coworkers were using it because I would find it around 50% sometimes lol
I have The SoundLink max its amazing but lmao there's so many other better speakers out there than on your list
Personally i find the x600 awful. Charge 5 comes to mind given your requirements or even soundlink max.
I suggest the bose soundlink max. I love the sound and its perfect for outside aswell. But thats just my opinion.
Your closest bet is Bose Soundlink Max. It adds 150 bucks to the bill with a sound comparable to the Go+Play 3. Some argue its better, but it just depends on your taste.
Name 5 things Bose is better than HK?
I know people who will go for Bose anytime. I hate the boxy sound plus it doesn't come cheap. HK price range and sound, nothing comes close.
I would suggest spend extra bucks and buy Bose sound link Max. You would enjoy the crisp and deep sounds.
I found myself the Bose Soundlink Max the best in terms of sound quality. If too expensive, then a Bose Flex Soundlink, the small one sounds powerfull and amazing, even outdoors for small parties and its only about 100 bucks and the beauty of it is that they can be paired in twos so it gives an wide stereo effect, still cheaper then a Max.
I think you'd be happy with either a sony ult field 5 or bose soundlink max.
I have a bose and while it is expensive: I find it to have the most clear sound and also the most portable of any speaker i own. Everything about it just feels premium
If it's in your budget, I say get all three, if you're planning to build a multi speaker system, then an Auracast setup would lean towards JBL. As far as the most authentic sound reproduction go with the Sony, if you like drums, and deeper Bass, that most certainly goes to the Bose. This is why it such a hard choice, but if you only needed one speaker, and you plan to use it a lot, the Sony checks all the boxes! I hope this helps since I own all three.
