Short answer: the JBL Flip 7 for the smallest neutral speaker, the Teufel Rockster Go 2 for stereo and battery. The Flip 7 is very neutral in a 1.2 lbs (560 g) body with IP68 protection and slightly deeper bass than the Flip 6 (59Hz at -10dB), though a 4kHz bump hurts it. The Rockster Go 2 uses two 50mm drivers and a passive radiator for stereo, claims 28 hours in Eco Mode, but has no app or 3.5 mm input and loses definition at maximum volume.
Buy the JBL Flip 7. It is rated higher for sound quality, and the $49.96 saving on the Teufel Rockster Go 2 is not enough to make up the difference.
