Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The EarFun Uboom L ranks #2 of 179 medium speakers by sound quality at $49.79; the Soundcore Select 4 Go ranks #25 of 62 small speakers by sound quality at $22.99.
Why pick the EarFun Uboom L: A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. It supports AAC Bluetooth, which the Soundcore Select 4 Go lacks. It keeps a wired aux input, which the Soundcore Select 4 Go lacks. It plays in stereo from a single unit, unlike the Soundcore Select 4 Go. Watch for: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
The Soundcore Select 4 Go is the lighter choice. A very inexpensive waterproof mini speaker with a strap, a long battery, app EQ, and stereo pairing. At 0.6 lbs (265 g) it weighs much less than the EarFun Uboom L at 1.4 lbs (650 g). Watch for: Not as deep of bass as higher ranked speakers.
Buy the EarFun Uboom L ($49.79) for a medium speaker; the Soundcore Select 4 Go ($22.99) suits a small speaker instead.
