Boom 2
Loud, bassy beast; needs EQ, no aux.

Harman kardon go + play 3 Its similar to the boombox but more for indoor use, HK and JBL are sister companies too.
Almost the same experience, but a colleague bought it. After some research, I got the Harman Kardon Go Play 3, and it's just perfect. I also have the original Boom Plus for outside use.
Earfun Uboom X in Oluv's custom 048 firmware from his patreon indoor mode. I have that and the Copenhagen 2.0, Vifa needs late night or party mode with desktop placment to sound good. With these settings, both are similar sounding - natural with tons of detail but Earfun sounds slightly better in almost every way, it has more detail, slightly more correct balance, noticeably deeper bass, slight stereo enhancement effect (soundcore calls it surround on x600 for example but this is correctly tuned unlike those). Copenhagen has slightly better dispersion and still slightly smoother transition from mids to treble, power is quite comparable which is incredibly impressive considering how thin the Vifa is... Heard Go+Play 3, bass comparable to earfun but too boosted and simply not as refined as the other two. I'm waiting to hear something that is better for indoor listening than the Uboom X.
Go play 3 is the only answer but get the max for beach and travel
It can put out some decent bass also on the go play 3 when you use the eq that most miss but its in the manual. How you liking the blast? I dont think its overhyped to be fair at that price but yeah, question marks over reliability. But even then they had no issues returning it. I agree on the Helsinki. I think once people mention immersion though they really need a pair of something. Maybe a pai of boom 2s might just be in budget.
You speaker recommendations are pretty flawed, the harman kardon go play 3 is not a out door speaker at all because of its exposed subwoofer, and no ip ratings. The motion x600 lacks deep bass, and its high-end can become fatiguing. The soundcore flare 2 and wonder boom are small and a downgrade in soundquality to the soundcore motion +. The UE wonder boom is the best speaker youve mentioned
I have an acton 3 and a Hk Go Play 3, Go play 3 is far better specially at higher volume and its portable too, portable Hk gp3 runs at 90W (plugged in 160W) which still outperforms acton 3 at 60W (plugged in obviously) Hk gp3 goes on sale a few times yearly, I got mine for $130 on Black Friday or Christmas I can’t remember.
