Short answer: the Teufel Boomster Go. It ranks #7 of 47 small speakers by sound quality; the JBL Clip 4 ranks #22.
On the Teufel Boomster Go side: Pretty deep bass and quite balanced overall for the size. The tradeoff: Distortion becomes audible above roughly 75% volume; at max volume up close it gets unclear and tinny.
What the JBL Clip 4 offers: Very light (0.4 lb) with a sturdy spring clip that attaches to bags/belts. Watch for: Quite a lack of bass. Not very loud.
Buy the Teufel Boomster Go if sound quality matters more than the price. Buy the JBL Clip 4 if the price matters more than sound quality.
