Short answer: the Teufel Rockster XS. It ranks #31 of 136 medium speakers by sound quality; the JBL Charge 4 ranks #50.
What the JBL Charge 4 offers: Doubles as a power bank for charging phones/tablets. Set against that: Not stereo. 1 Oval driver.
The case for the Teufel Rockster XS: A good sounding speaker. The catch: Not quite as deep of bass as others.
One note: the JBL Charge 4 is discontinued, but it still ranks #50 of 136 medium speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the JBL Charge 4 if the price matters more than sound quality. Buy the Teufel Rockster XS if sound quality matters more than the price.
