Short answer: the JBL Go 4. It ranks #27 of 49 at $49.95, $40.05 less than the Harman Kardon Neo at #45. The Go 4 gained a little more bass over the Go 3 and fixed the strange mids peak, but still has not much bass past about 50% volume; the Neo is IPX7 waterproof with a huge lack of bass.
Buy the JBL Go 4. It is rated higher for sound quality; the Harman Kardon Neo is no longer sold new.
If water resistance matters to you, the JBL Go 4 at IP67 (brief submersion) holds up far better than the Harman Kardon Neo at no water resistance.

JBL Go 4: $49.95 Amazon B&H Photo Video eBay
Newer model: the JBL Go 5, ranked higher, rated 3.2/5.
Pros: A little more bass than the Go 3 and they fixed the strange mids peak. Measured bass extension of ~82Hz (-10dB).
Cons: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume. Midrange can sound grainy and treble a bit sizzly; loses clarity at higher volumes.
