Short answer: the Bogasing M4 for sound, the JBL Go 5 for IP68 durability. At $54.95 against the M4’s $45.99, the Go 5 brings an IP68 rating, up from the Go 4’s IP67, and AirTouch tap-to-pair stereo linking, but it is still overpriced and not very different from the Go 4 besides the lights. The M4 sounds most balanced in super bass mode but is a bit harsh and thin. The Bogasing M4 is discontinued; its replacement is the Bogasing M5.
Buy the Bogasing M4 at $45.99 if you want a medium speaker. Buy the JBL Go 5 at $54.95 if you want a small speaker instead.
Battery life favors the Bogasing M4: rated for 24 hours against 8 hours for the JBL Go 5.
