Short answer: the Klipsch Austin for bass, the JBL Go 4 on price. The Austin ranks #15 of 62 with dual passive radiators that give more low-end presence than most mini speakers, though its bass is not as deep as the higher ranked speakers. The Go 4 costs $49.95, $5 less but still has not much bass past about 50% volume.
Buy the Klipsch Austin. It is rated higher for sound quality, and the $5 you would save on the JBL Go 4 does not close the gap.
If battery life is a priority, the Klipsch Austin is rated for 12 hours versus 7 hours for the JBL Go 4.
