Short answer: the Ultimate Ears Wonderboom 4 for a small USB-C speaker, the Tribit Xsound Surf for its rugged frame. The Wonderboom 4 is small but its bass is not as deep as the top-ranked speakers and sounds a little thuddy, and it is not much of an improvement over the Wonderboom 3 besides the USB-C port. The Surf is about 20% louder than the XSound Go, yet its bass does not go as deep as others and it has strange midrange peaks.
Buy the Ultimate Ears Wonderboom 4 if you want one new; the Tribit Xsound Surf is discontinued, so only look for it used.
