Short answer: the JBL Clip 4, if you are buying new. The Teufel Boomster Go ranks higher than it (#7 vs #22 of 50 small speakers, 4.2/5 vs 3.4/5) but is discontinued, so only consider it used; the JBL Clip 4 is still sold new at $49.95.
Buy the JBL Clip 4 new; the Teufel Boomster Go is no longer sold new, so it only makes sense as a used find.
