Short answer: the Soundcore Boom Go 3i. It ranks #2 of 62 small speakers by sound quality (rated 4.4/5) at $59.98 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 Soundcore Boom Go 3i is the better-sounding, longer-running option. A tough, floating mini speaker with full waterproofing, a long battery and a detachable strap, built for travel and the outdoors. It is rated for 24 hours of battery against 12 for the Vifa City. It is rated IP68 against IPX4 for the Vifa City. It links with other speakers (Auracast), which the Vifa City cannot. The tradeoff: This is still a 15W mono speaker: bass impact and stereo width are limited, and critical listeners may find the upper treble piercing or metallic.
The Vifa City is the lighter pick. A small, stylish speaker with detailed, balanced sound and clear vocals even at low volume, and stereo pairing. At 0.7 lbs (300 g) it weighs noticeably less than the Soundcore Boom Go 3i at 0.8 lbs (380 g). The tradeoff: Dip at 1200Hz.
Buy the Soundcore Boom Go 3i. It is rated higher for sound quality and still sold new, while the Vifa City is discontinued.
