soundcore - Flare 2 (A3165Z11)

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

You could get anker soundcore flare 2 and pair it with the app to play white noise.

Got mine for $43 ha! Still waiting for it though. Cant wait to try it out! My last BTS is Soundcore Flare 2

It was on sale when i bought it online, plus using the discount voucher. Using the shopee app (ph). Im using it right now and and i like it very much especially getting it at a cheap price. Doesn't hurt my ears listening to it even at 90% volume, the bass is superb. I could say its perfect for me. What i regret about it is not buying another 1 for tws sound.

A lot of Bluetooth speakers have narrow/directional/on-axis soundstages, where the listening experience really drops off drastically unless you are situated right in front of the speaker.  So for a group of people listening it would be better to get something 360°/omnidirectional.  Ultimate Ears has speakers designed for that, like the Wonderboom or Megaboom depending on your price range.  There are also spatial audio speakers also like soundcore motion x600 and Harmon Kardon go + play 3. I love the Soundcore Flare 2, a 360° stereo speaker that you might only be able to find used.  It's permanently in my work bag for music in the office, although it's an outdoor speaker.  It's in the same class as the UE Wonderboom I guess but with lower frequency extension.

My cheap Amazon Anker Sound core is still going strong! Great little speaker for the money!
