Short answer: the KEF Muo gen2 for tonal balance, the Tribit Xsound Surf if you need more volume. The Xsound Surf has a rugged rubberized frame and metal grille and runs about 20% louder than the XSound Go at the same volume, but its bass does not go as deep as others and it shows strange midrange peaks. The Muo gen2 fixes the rolled off treble and overall balance, though its bass is very thuddy.
Buy the KEF Muo gen2. It is rated higher for sound quality, and the Tribit Xsound Surf is discontinued, so it is only available used.
If battery life is a priority, the KEF Muo gen2 is rated for 24 hours versus 10 hours for the Tribit Xsound Surf.

The Two Speakers In Full
KEF Muo gen2: $249.99 Amazon eBay
Pros: KEF seemed to have fixed the rolled off treble and overall balance
Cons: Lacking deeper bass. Very thuddy bass. Appears to be the exact same hardware but with updated tuning. Bass distorts as volume increases, and the claimed 43Hz extension is really only audible at low listening volumes, with a few seconds of lag after volume changes. Loses most of its bass off-axis. Customer reviews are mixed, ranging from praise for detail at low volume to complaints of a boxy, hollow sound.
