Short answer: the Harman Kardon Luna 2 for out-of-the-box balance, the Soundcore Motion 300 for portable flexibility. The Motion 300 is pocket size, can face you in stereo or lie flat for omnidirectional sound, and holds a custom EQ per orientation, but without that EQ its treble is very rolled off. The Luna 2 has the tighter, better-controlled bass from its 62mm x 82mm woofer and passive radiator, at $199.95 against $79.99.
Buy the Soundcore Motion 300. It is rated higher for sound quality than the Harman Kardon Luna 2 and costs less, which makes it the one to get unless you need something the other one does better.
