Short answer: the Teufel Boomster Go for sound, the JBL Go 3 for pocket size. The Boomster Go ranks #7 of 54 with pretty deep bass and a quite balanced sound for its size, though distortion becomes audible above roughly 75% volume and it gets unclear and tinny at max volume up close. The Go 3 is pocket-sized at 0.5 lbs (209 g) with not much bass and a strange mids peak.
Buy the JBL Go 3 if you want one new; the Teufel Boomster Go is discontinued, so only look for it used.
