Short answer: the Tribit Stormbox Micro 2. It ranks #1 of 62 small speakers by sound quality (rated 4.5/5) at $35.39 and is still sold new; the Vifa City ranks #10 (rated 4.0/5) and is discontinued, so it is only an option used.
The Tribit Stormbox Micro 2 is the better-sounding, deeper-bass choice. An excellent sounding small speaker, with surprisingly deep bass for its size and a strap that holds it on a bike or backpack. Its bass reaches about 65Hz before falling 10dB, against 73Hz for the Vifa City. It is rated IP67 against IPX4 for the Vifa City. It has an adjustable EQ, which the Vifa City lacks. The catch: Finicky phone charging, which doesn’t usually work.
What the Vifa City does well: A small, stylish speaker with detailed, balanced sound and clear vocals even at low volume, and stereo pairing. The tradeoff: Dip at 1200Hz.
Buy the Tribit Stormbox Micro 2. It is rated higher for sound quality, and the Vifa City is discontinued, so it is only available used.
