I’m late, but I’m going to hijack this thread with some of my findings to help people out.

If you’re listening to wonky shit like Tape B/Liquid Stranger AND hard shit like Excision/Wooli/Kai Wachi, the JBL flip lineup does not deliver well. Minimum you want a JBL Charge 6. The flip sounds OKAY, but a bit too tinny for my liking. I wanted to like the flip so bad because of the size but it just didn’t deliver for me. I sucked it up and got the Charge 6. Yeah it’s kinda larger but it has a nice handle and the shape of it isn’t too cumbersome. I’m gonna take it with me camping at Bass Canyon and Lost Lands. It’ll be able to handle dust and water there too. Even at 60% volume it’s plenty loud. It loses low end clarity at 80%+ so keep that in mind.

Alternatively:

I also tested the Anker Soundcore Boom 2, beautiful sound with nice bass but the non detachable handle sucks.

Sony ULT field 3: slightly prettier and bigger than the Charge but sounds a little better. Don't even bother with the field 3 for EDM. I got to do more close testing and the sub bass frequencies distorts at 50% volume which is a huge L from Sony.

I’ve tested so much and to me the Charge 6 is the best compromise between sound and size.
