Short answer: the JBL Charge 6 for measured bass reach, the Rockster Go 2 for lighter, tougher portability. The Charge 6 is IP68, claims 24 hours and 45W, and its measured -10dB point is 53Hz, with a more neutral response than a Charge 5 once EQ is applied. The Go 2 is lighter at 1.6 lbs (0.74 kg) and claims 28 hours in Eco Mode, but it loses definition at maximum volume and its battery claim is optimistic for loud playback.
Buy the JBL Charge 6. It is rated higher for sound quality, and saving $19.96 with the Teufel Rockster Go 2 does not make up for the sound-quality gap.
If battery life is a priority, the JBL Charge 6 is rated for 24 hours versus 15 hours for the Teufel Rockster Go 2.
